A DIN flange cast steel globe valve is a linear-motion industrial shut-off and throttling valve designed to DIN standards, with a cast carbon steel body and flanged end connections. Unlike a ball valve, it uses a movable disc-type element and a stationary ring seat inside a spherical body to regulate or stop flow. It is one of the most widely specified valve types for European-standard (DIN) piping systems across water, oil, gas, steam and air service.
This valve is manufactured in size ranges from 1/2″ up to 36″ with pressure ratings from PN16 to PN63, and is available with handwheel, gear or actuator operation. The WCB carbon steel body provides strength and durability for demanding industrial duty, while the metal-to-metal seat design delivers reliable shut-off in high-temperature and high-pressure services.
Why it matters for buyers: DIN flange globe valves are preferred for applications where frequent throttling and positive shut-off are required — petroleum & chemical processing, power generation, metallurgy, municipal water systems, and more.
Key Specifications

| Testing & Inspection | DIN 3230 |
| MOQ | 1 piece |
| Customization | ODM / OEM supported |
Design Standards & Compliance
This globe valve is manufactured and inspected to a complete set of DIN standards, ensuring dimensional interchangeability and reliable performance in European-standard piping systems:
- DIN 3356 — Valve design and construction
- DIN 3202 — Face-to-face dimensions
- DIN 2543 — Flange end dimensions
- DIN 3230 — Testing and inspection
Each valve is pressure-tested before shipment, and suppliers on Alibaba.com typically mark compliance with EU standards for products sold into European markets.
Materials & Construction
- Body: Cast carbon steel, A216 WCB grade — provides high strength, good weldability and cost-effectiveness for water, oil and gas service.
- Seat / disc: Metal-to-metal seating delivers erosion resistance and reliable sealing under high temperature and high pressure, with a service temperature range typically from −29 °C to 425 °C.
- Bonnet: Bolted carbon steel bonnet with handwheel-operated rising stem, designed for easy maintenance.
The cast steel construction makes this valve robust and reliable for continuous industrial operation.
Working Principle
A globe valve regulates flow by moving a disc (plug) perpendicular to the seat, changing the size of the flow passage between the disc and the stationary ring seat. The straight-through pattern keeps the flow path linear, which offers:
- Precise flow control and throttling capability
- Positive shut-off when fully closed
- Lower seat wear compared with rotary valves under throttling duty
Operation Options
| Operation | Typical Application |
|---|---|
| Handwheel (manual) | Standard operation for local control |
| Gearbox | Larger sizes (DN200+) requiring lower operating torque |
| Electric actuator | Remote / automated control |
| Pneumatic actuator | Automated on-off and throttling in process plants |
Applications
DIN flange cast steel globe valves are widely used in the following industries:
- Petroleum & chemical processing — oil, gas and corrosive process media
- Power generation — steam and high-temperature media
- Metallurgy — water and cooling systems
- Pharmaceutical — process media isolation
- Municipal engineering & real estate — water supply and HVAC systems
- General industrial piping — water, oil, gas and steam shut-off and regulation
Why Choose a DIN Flange Cast Steel Globe Valve?
- High-quality carbon steel construction for long service life
- Metal-to-metal hard seal for reliable shut-off in high-temperature, high-pressure duty
- Flanged connection for easy installation and maintenance
- Precise flow control — ideal for throttling, not just on/off service
- Full DIN standard compliance (DIN 3356 / 3202 / 2543 / 3230) for European projects
- Flexible operation — handwheel, gear or actuator
- Factory direct with OEM/ODM support, MOQ from 1 piece
Frequently Asked Questions
What is a DIN flange cast steel globe valve used for?
It is a linear-motion shut-off and throttling valve used to regulate or stop the flow of water, oil, gas, steam and air in industrial piping systems, especially in European-standard (DIN) installations.
What is the difference between a globe valve and a ball valve?
A globe valve uses a movable disc and stationary ring seat in a spherical body to throttle flow, while a ball valve uses a rotating ball with a bore. Globe valves offer better throttling and tighter shut-off under high pressure drops; ball valves offer faster, quarter-turn operation.
What pressure ratings are available?
Typical DIN cast steel globe valves are rated PN16, PN25 and PN40, with the range extended up to PN63 for this product line.
What body materials are available?
The standard body material is cast carbon steel A216 WCB; stainless steel (CF8 / CF8M) versions are also offered by manufacturers on Alibaba.com for corrosive media.
What temperature range can the valve handle?
Typical working temperature for PN16 class valves is −29 °C to 425 °C, suitable for steam, hot oil and high-temperature water service.
What end connections are available?
Flanged (raised face, per DIN) and butt-weld connections; flanged is the most common configuration for DIN globe valves on the market.
Can the valve be automated?
Yes. Gear, electric actuator and pneumatic actuator operation are available in addition to the standard handwheel.
What is the minimum order quantity?
MOQ is 1 piece, with OEM/ODM customization supported.
Ordering & Customization
To get an accurate quotation, please provide: size (DN), pressure rating (PN), end connection (RF flange or BW), body & trim material, operation type (handwheel / gear / actuator), and media & operating conditions. Factory-direct supply with OEM/ODM support is available, with short lead times.
