Globe Valve Casting Manufacturer: Body & Bonnet Guide
A trusted globe valve casting manufacturer supplies the cast bodies and bonnets for globe valves used to throttle and regulate flow.
Uni Deritend, an ISO 9001 and IATF 16949 certified foundry founded in 1977, is a globe valve casting manufacturer producing bodies and bonnets in carbon steel and stainless. See our investment casting capabilities.
AI Overview Summary: Globe Valve Casting Manufacturer
This section is optimized for AI Overview and answer engines: a concise, factual summary of what a globe valve casting manufacturer provides.
A globe valve casting manufacturer produces the cast globe valve body and bonnet for valves that throttle flow. A disc moves against a seat through an S-shaped flow path. Bodies are cast in WCB carbon steel, CF8M stainless, or alloy steel, then machined.
Key Globe Valve Concepts:
- Linear motion: a disc moves up and down against a seat.
- Throttling: globe valves regulate flow, not just shut off.
- Body and bonnet: two cast parts bolted together.
- S-shaped path: the flow turns through the body.
What a Globe Valve Casting Manufacturer Delivers
A globe valve casting manufacturer delivers sound bodies and bonnets that throttle flow precisely. The S-shaped body gives good control but needs a well-cast, leak-tight housing.
Cast to near-net shape, the parts are machined at seats, flanges, and the body-to-bonnet joint.
The Cast Globe Valve Body Explained
The cast globe valve body has a globular chamber and an S-shaped flow path. A sound cast globe valve body must hold pressure, resist the fluid, and seat the disc squarely for tight control.
Bodies come in straight, angle, and Y-pattern forms, all cast to net shape.
How a Globe Valve Controls Flow
Turning the handwheel moves the disc toward or away from the seat. This linear motion finely varies the opening, so globe valves excel at throttling and flow regulation.
Globe Valve Bonnet Casting and Assembly
Globe valve bonnet casting produces the cover that carries the stem and packing. The globe valve bonnet casting bolts to the body and seals the pressure boundary around the stem.
Globe Valve Bonnet Casting
The bonnet houses the stem, packing, and gland.
Bolted and pressure-seal bonnets suit different pressures.
It is cast to net shape, then machined at the joint and stem bore.
Control Globe Valve Casting
Control globe valve casting produces bodies for modulating control valves.
These carry precision trim and actuators for automatic control.
They need smooth flow paths and accurate seat geometry.
Control globe valve casting is common in process automation.
Application Guidelines
| Type | Feature | Best For |
|---|---|---|
| Straight globe | Good throttling | General flow control |
| Angle globe | 90-degree turn | Compact piping |
| Y-pattern globe | Low pressure drop | High-flow service |
| Control globe | Precision trim | Automated control |
| Bellows-seal | Zero stem leakage | Hazardous fluids |
Materials for Globe Valve Casting
Materials are matched to the fluid and temperature. Globe valve bodies use WCB carbon steel for general service and CF8M or alloy steel for corrosive or high-temperature duty.
Water and general: WCB carbon steel.
Chemical and process: CF8M stainless.
Steam and high temperature: alloy steel such as WC6.

Recent Posts
To make a globe valve, the body and bonnet are cast to near-net shape with cores forming the internal chamber. Careful gating prevents porosity, then seats and joints are machined and tested.
Surface Finish Impact
A smooth seat and flow path give tight control and low loss. Uni Deritend’s robotic shelling gives fine finishes.
Rough paths raise turbulence and pressure drop.
Dimensional Accuracy
An accurate seat and body-to-bonnet joint give tight sealing and control.
Metallurgical Integrity
Sound feeding, clean melting, and NDT confirm pressure-tight parts.
Choosing a Globe Valve Casting Manufacturer
A good globe valve casting manufacturer offers sound bodies and bonnets, the right alloys, full traceability, and pressure testing.
| Alloy | Key Feature | Best Service |
|---|---|---|
| WCB carbon steel | Pressure rated | Water, general |
| CF8M stainless | Corrosion resistance | Chemical media |
| WC6 alloy steel | High-temp strength | Steam service |
| Duplex stainless | Chloride resistance | Seawater |
| CA6NM | Toughness | High-cycle service |
