Product Overview

Flow through this valve is set by a disc that travels down onto a seat rather than by a gate sliding across the bore. That single design choice is why a DIN globe valve is the pattern plants reach for when a line has to run at part load: the disc can be stopped anywhere between shut and wide open and it holds that position while the pump curve, the header pressure or the process temperature stays steady. The body is cast in a spherical form, the bonnet is bolted down over the top, the stem rises as the valve opens, and the handwheel sits clear above the assembly where insulation and pipework will not foul it. Importers and regional globe valve suppliers stock it for catalogue replenishment, project teams use it on pressure-reducing branches and bypasses, and OEM buyers take the same body cast, machined and marked to their own specification. Matching an existing installation is usually harder than choosing a size, which is why the grade, nominal size and pressure class are cast into the body of every unit and stay readable long after delivery. On networks that mix standards, a project can be sourced from one plant with one set of documents. - Throttling that holds a setting. The disc moves square onto the seat instead of sliding across the bore, so a part-open valve keeps a steady flow; that is why globe valves are used on pressure-reducing branches, bypasses and dosing lines rather than for isolation only. - DIN dimensional compatibility. Flange drilling and face-to-face dimensions follow German DIN practice, so the valve lines up with the pipework, gaskets and bolt sets already specified on a DIN project. - A rising stem you can read at a glance. The threaded stem climbs out of the bonnet as the valve opens and drops back as it shuts, giving a mechanical position check with no gauge and no actuator feedback to wire in. - Handwheel operation with no power supply. Manual control keeps the valve usable on unpowered skids and remote stations, and the multi-spoke handwheel gives enough leverage to seat the disc firmly by hand. - Cast markings for goods-in checks. Grade, size and pressure class are cast into the body, so a storeman or inspector can check the unit against the line list without opening the paperwork. - Sealing faces cut to match the disc. The seat is machined so the disc lands flat across the full face, which is what keeps a closed valve tight on water, steam and chemical duty.

Construction and Service Access

The body is a single cast form with the seat cut into the internal passage and the bonnet bolted down over the top. Because that joint is bolted rather than welded, the disc and the seating faces sit directly under the bonnet: undo the nuts, lift it clear, and the working parts are in front of you without cutting the valve out of the line. On a plant with hundreds of valves, that is the difference between a planned job during a shutdown and a hot-work permit.

Above the bonnet, the stem carries the handwheel and rises through the packing as the valve opens. The exposed thread is a diagnostic as much as an indicator: a stem that will not climb smoothly usually means the seat or the disc needs attention, not that the handwheel is stiff.

Flange faces on this flanged globe valve are machined flat to take a standard gasket, so the joint pulls up evenly instead of a soft gasket compensating for a rough face. The exterior is painted to protect the casting through storage and service, and the paint stops short of the machined flange faces so nothing has to be scraped off before bolting up.

Where a valve is worked hard, keep a bonnet gasket and a disc on the shelf rather than a complete spare valve. The body and flanges rarely fail; the parts that wear are the ones under the bonnet, and they come out with hand tools.

Sizing and Pressure Class

Read the line size first. Take the DN from the pipe schedule or from the markings on the valve being replaced, and check that the new valve leaves the same space in the run, because a flange that matches but a body that fouls an adjacent fitting is still a return.
Set the pressure class from the worst case, not the normal one. A pump dead-head, a closed outlet or a surge can push a line well above its working pressure; the series is built up to 42 MPa and we confirm the class against your own figure.
Give the temperature at the same time.
Match the flange before the order is finalised. Send the mating flange standard, nominal size, pressure rating and gasket type so the drilling and the face finish meet the pipework already welded in.
Agree the documentation with the valve. Ask the globe valve manufacturer to list material certificates, pressure-test records and any third-party inspection with the quotation, so nothing has to be added after approval.
Confirm the standard pattern the drawing follows. A GOST line takes the Russian standard threaded globe valve rather than this DIN pattern, and mixing the two on one line is the usual cause of a flange that will not marry up. 7.

Operating Environments

Municipal water supply and distribution. On treatment-plant pipework and distribution mains, the throttling range is used to hold pressure and soften the surges that split pipe; the corrosion-resistant body grades stand up to treated water over long service intervals. - Steam, boiler-house and power lines. A cast steel globe valve with a bolted bonnet suits steam headers and boiler-house branches, where the valve is worked through the day and the stem position has to be readable from the walkway. - Chemical and process dosing. Stainless bodies take aggressive media, and the fine throttling range lets an operator trim a dosing line without changing orifice plates or adding a control valve. - Distributor and importer stock. Buyers holding a DIN series for a regional market order a size ladder on one purchase order, so the shelf carries more than the one DN that always sells out. - Retrofit and replacement work. When a valve in an existing DIN line fails, the cast markings on the old body give the size and class, and the new flanged globe valve bolts straight onto the flanges already in the line.

Ordering & Delivery

Send the line data with the inquiry: nominal size, pressure class, working temperature, medium, flange standard and the quantity you expect to run. As a globe valve manufacturer we quote from those figures rather than from a stock list.
Check that the quotation names the pattern and the class, not only the size. An American line class is raised as an ANSI globe valve to the class on your drawing, so the flange drilling and the documents match the pipe it goes into.
Agree the documents and the pattern together. Where the drawing names a compact forged valve, the order is raised as an API 602 globe valve rather than this cast body, and the certificates follow the pattern quoted. Quality management is certified to ISO9001, with ISO14001 and ISO45001 covering environmental management and occupational safety, and those certificates go out with the order papers.
Fix the commercial terms on the quotation: quantity, price basis, lead time, payment terms and shipping terms are confirmed there for your order rather than assumed from a catalogue entry.
Confirm packing and shipping when the order is placed, including export packing, container loading and the port of departure, so the goods leave on the schedule your forwarder is working to.
Place the order against a revision-controlled drawing. Distributors and globe valve suppliers running a repeat programme get the same drawing, the same marks and the same documentation on every release.
GOST items, including the Russian standard threaded globe valve, can go on the same order and are quoted alongside this DIN series.

FAQ

What materials are used in your DIN globe valve production?

Bodies are supplied in HT200 grey iron and QT450 ductile iron for water and drainage duty, WCB carbon steel for steam and higher-temperature service, and CF8 stainless steel for chemical and corrosive media, with forged and cast steel options where the line class calls for them. The grade is chosen against the medium before the valve is quoted, because the same DN can need a different body depending on what runs through it.

Can you customize DIN globe valves for special pressure or size requirements?

Sizes run from DN15 to DN1200 and pressure ratings go up to 42 MPa, all built to German DIN practice, so most special requirements fall inside the standard span. Send the size, class, medium and flange standard with the inquiry and we will confirm the pattern, the body grade and the documents that go with it.

How do you ensure ease of maintenance and long service life for your valves?

The bonnet is bolted, so the disc and seating faces come out through the top of the body without disturbing the pipework, which is the single biggest factor in how long a valve stays in service. Sealing faces are machined square to the disc so the valve closes tight, and body grades such as WCB and CF8 hold their strength in high-temperature and corrosive duty. Keep a bonnet gasket and a disc on the shelf and most repairs are done with hand tools.

When should I choose a globe valve instead of a gate valve?

A globe valve is the right choice when the line is throttled, whether for pressure reduction, a bypass, dosing or a branch that is adjusted through the day, because the disc holds any position between shut and wide open. A gate valve belongs on lines that are either fully open or fully shut. If the duty is mainly isolation with only occasional adjustment, say so with the inquiry and we will tell you whether the globe pattern is the better fit for that line.

Do you supply globe valves to standards other than DIN?

German DIN is the standard this series is built to. The same plant also works as a Russian standard globe valve manufacturer, and the Russian standard threaded globe valve covers GOST drawings where the connection is threaded rather than flanged. Tell us the standard number and the connection type and we will quote the matching pattern rather than a near equivalent.

Can you quote an ANSI globe valve or an API 602 globe valve for a different line class?

Yes. American line classes are quoted as an ANSI globe valve to the class on your drawing, and where a compact forged pattern is specified the API 602 globe valve is quoted instead of this cast body. Send the class, size and medium together so both patterns are not confused on the same order.

What should I check when the valve arrives?

Match the cast markings against the packing list, size, grade and pressure class first, then run the handwheel through its full travel to confirm the stem rises and returns without catching. Look over the flange faces for transit damage, leave the blanking covers on until the valve goes up, and file the material and test records with the order. Anything out of place is far easier to settle before the valve is bolted into the line.
