Product Overview

Longyao Woyu Valve Co., Ltd. has been building valves since 2012 and works from a 12,000 m² plant in Shangli Industrial Park, Longyao County, Hebei, in the Beijing–Tianjin–Bohai economic belt. The team's valve-making record runs past 15 years, and it shows in a catalogue built around four duties — isolation, throttling, filtration and quarter-turn control — through gate, globe and ball valves, butterfly valves, check valves, strainers, pressure-reducing valves and plug valves. The depth is deliberate: a plant schedule that needs eight different valve types can be filled from one production floor instead of four.

The range is multi-standard by design. A single works holds the national patterns that different export markets write into their specifications, so an importer restocking one standard series and a utility specifying another are served from the same factory. Mixed-standard orders are where this pays off. Flange drilling, face-to-face length and pressure class each have to agree with a different national practice at once, and doing that under one roof removes the guesswork of pairing parts from two or three suppliers.

Buyers reach us from four directions. Importers and regional distributors restock a standard series and need the sizes they sell to stay available between orders. Water supply, wastewater and irrigation projects need valves that match a specification schedule and arrive with the paperwork the engineer asked for. Shipyards and marine spare suppliers are usually replacing a valve already in service, which is where marine cast steel globe valves and the gate and check valves around them come in, ordered against the number stamped on the existing valve. Plant maintenance teams need one size that fits a line installed years ago, often with little headroom above the handwheel.

Our management systems are certified to ISO 9001:2015 for quality and ISO 14001:2015 for environment, and the company also holds occupational health and safety management system certification. Material certificates, pressure-test records and third-party inspection reports are agreed at quotation stage, so the documents your engineer needs are settled before production begins rather than chased afterwards.

Globe Valves and Marine Series

Globe valves are the throttling valve in most of the schedules we quote. The disc lifts off its seat to regulate flow rather than only opening or closing, which is why a globe valve holds a set point on water, steam and chemical lines where a gate valve gives you full bore or nothing at all. Globe valve manufacturers are expected to hold the national pattern the buyer's specification was written to, and we keep DIN, GOST and JIS bodies in production side by side. The DIN cast steel range runs from DN15 to DN1200 for throttling duty in water, steam and chemical service. The Russian series is a forged steel body with GOST threaded ends, built for throttling and shut-off in Russian and Central Asian pipelines where a flanged joint is not wanted; threaded ends also make a line easier to break for maintenance. Both are quoted to the pressure class and body material on your line list. Shipboard work is where the standard number carries the most weight. Between the two, the JIS F7319 globe valve is the cast steel choice for throttling and shut-off positions, while the cast iron F7307 pattern covers the lighter services. A marine globe valve order usually starts with the number cast on the old body, which is the part of the job a marine globe valve manufacturer is judged on: match the number, the flange drilling and the size, and the spare drops in without rework. If a drawing calls for a marine bronze globe valve, send the JIS F number and the size and we will confirm which body material we can offer against it before the order is placed. Forged and cast steel line-class globe valves are quoted to your line class, so the pressure and temperature rating on your enquiry is the one we build to.

Applications & Industries

Petroleum and petrochemical — Gate valves for isolation and globe valves for throttling on process and utility lines, where the pressure class and body material come straight off the line list.
Chemical processing — Globe and ball valves for flow regulation on feed, dosing and utility lines where the medium attacks cast iron and carbon steel.
Electric power — Cast steel gate and globe valves for steam and water circuits, built to the temperature rating the plant writes into its specification.
Metallurgical and steel plant — Cast iron and cast steel gate, globe and butterfly valves for the water and process circuits around furnaces, casters and rolling lines.
Municipal engineering — Flanged gate valves and butterfly valves for distribution mains, pump stations and reservoir connections, matched to the pressure class of the network.
Sewage disposal — Non-rising stem gate valves and check valves on effluent and sludge lines, where a shallow chamber decides the stem type.
Irrigation works — Gate and butterfly valves for canal, pump station and field distribution work, in sizes matched to the buried main.
Pharmaceutical manufacturing — CF8 stainless valves for clean water, purified water and utility circuits where the process demands a stainless wetted path.
Shipbuilding and dry-dock repair — Ballast, bilge, cooling and fuel-oil circuits take most of the marine valve volume. Throttling positions usually go to a JIS F7319 globe valve from a marine globe valve manufacturer, with JIS marine gate and check valves for isolation around it, ordered to the flange drilling of the ship's piping.

Ordering, Documentation & Project Support

Send the line data. Standard number, valve type, size, pressure class, body material and end connection, plus the medium and working temperature. A photo of the nameplate or a marked-up drawing of the valve being replaced is usually faster than a written description. For marine items, the F number, the size and the flange pattern are enough to start — a marine globe valve manufacturer reads those three details faster than a description. 2. We confirm the pattern and the material. Which series the item falls under, which body material we can offer, and the production slot. Anything outside the catalogue is handled the same way. The same applies to marine cast steel globe valves, JIS F7319 10K, in a size we do not hold, or a body grade beyond HT200, QT450, WCB and CF8. 3. Agree the documents. Material certificates, pressure-test records and third-party inspection are fixed here, so the file that ships matches what your engineer expects. If an inspector needs to witness testing, say so at this stage so the visit lines up with the production slot rather than the packing date. 4. Agree the packing. Valves travel with flange faces, stems and trim protected through handling and sea freight. Confirm the packing standard and the case marking your site or warehouse needs before the cases are closed. 5. Confirm the commercial terms. Price, quantity, payment terms, delivery date and shipping terms are confirmed on the quotation for each order. Ask your sales contact for the current lead time and terms before you schedule installation. 6. Send it to the works. WOYU-VALVE@outlook.com, by phone or WhatsApp on +86 150 1136 6950 or +86 150 1131 2311, or to No. 6 Shangli Village Industrial Zone, Longyao County, Xingtai City, Hebei, China. - Clean the body pad before anything else. The standard number, nominal size and pressure class are cast or stamped into the body, usually on a flat pad opposite the bonnet or beside one flange, and paint, scale or marine growth will hide them until the pad is wire-brushed. - Measure the flange in four numbers: outside diameter, bolt circle diameter, bolt hole diameter and bolt count. JIS B2220, ANSI class and DIN PN flanges do not share a bolt pattern, so these four settle which standard the line was built to. Note as well whether the face is raised or flat, because that decides the gasket the joint takes and a replacement with the wrong face will not seal. - Take the face-to-face length between flange faces. Short-pattern and long-pattern bodies of the same size differ here, and this is the dimension that decides whether a replacement drops into the gap in the line. - Record the end connection and the bonnet style. Threaded ends indicate GOST pipework, socket weld indicates small-bore industrial lines, flanged ends cover most JIS and ANSI/AWWA work, and a bolted bonnet with a rising stem belongs to a different pattern family from a non-rising stem body. - Rough-test the body material on site. A magnet and a spark test taken from a cleaned spot separate cast iron from cast steel and stainless in most workshops; the medium, working temperature and pressure class then confirm which grade is acceptable for that duty. - Match the F number where one survives. Aboard ship that casting number is the shortest route to the right item, and JIS F7319 10K fixes a bolted-bonnet body with JIS B2220 flanges, 0.98 MPa nominal pressure and sizes DN50 to DN300. - Send the set when the number is gone: a photograph of the body pad, one of the flange face with a rule laid across it, one of the bonnet and stem, plus the medium, working temperature and line pressure. Globe valve manufacturers read a replacement from those details rather than from a written description. - From the same details we will name the item, confirm whether a marine globe valve or an industrial pattern belongs in the line, and quote it in writing before production starts.

FAQ

Which body material should I specify — HT200, QT450, WCB or CF8?

HT200 is grey cast iron and suits lower-pressure water and utility duty. QT450 is ductile iron, chosen where the line sees shock, vibration or a working pressure that grey iron does not handle comfortably. WCB is carbon steel for higher pressure and temperature service, and CF8 is the cast stainless grade for corrosive media or where the process requires a stainless wetted path. The medium, working temperature and pressure class on your line list decide which of the four is acceptable; send the service conditions and we will confirm the material against them.

How do I match a valve that is already installed in the line?

Start with the marking on the body — standard number, size and pressure class are usually cast or stamped into it. Then measure the face-to-face length, the flange outside diameter, the bolt circle and the number of bolts, and note whether the flange face is raised or flat. Globe valve manufacturers build to those dimensions, so the measurements identify a replacement faster than any description. A photo of the nameplate and one of the flange with a rule in shot is enough for us to confirm.

What is the difference between a rising stem and a non-rising stem gate valve?

A rising stem valve lifts the stem as it opens, so the height of the handwheel tells you how far open the valve is from a distance — useful on a plant walk-round and simple to automate. A non-rising stem keeps the stem inside the bonnet and the handwheel in one place, which holds the overall height down, and that is why the non-rising version appears in shallow chambers, under decks and against walls where a rising stem would foul. Both give the same isolation; the difference is the space above the valve.

How are the valves tested before shipment?

Pressure testing is carried out to the class the valve was built to, and the records travel with the shipment. Where a project or inspection requirement calls for witnessed testing or third-party inspection, it is written into the quotation so the visit is scheduled against the production slot rather than after the valves are packed. Tell us at enquiry stage which records your engineer needs and they are agreed with the price.

Can you supply a marine globe valve in bronze instead of cast steel?

A marine bronze globe valve is a different casting from our cast steel and cast iron patterns, so it is quoted case by case. Send the F number, the size and the pressure class and we will confirm what can be offered for that item before you commit. Where bronze is not available for the position, the JIS F7319 globe valve in cast steel covers the same duty and the cast iron F7307 pattern handles the lighter services.
