Cast Steel Fixed Ball Valve
Introduction
The Cast Steel Fixed Ball Valve is a high-pressure shut-off valve made of cast steel, containing a fixed (trunnion-mounted) ball. The ball is supported at both ends, preventing it from moving with pipeline pressure.
Parameters
- Size: 2"-40"
- Class: 150-900LB
- Two&Three Pieces Cast Steel Body
- Anti-static Device
- Blow-out Proof Stem
- Fire Safe Design
- Emergency Sealant Injector
Advantages
Fixed Ball Structure
The ball is supported by trunnions (top and bottom) and will not move under pressure.
Lower Operating Torque
Because the ball is fixed, the force on the seat is less, thus reducing the operating torque and making the valve easier to turn.
Reliable Sealing Performance Under High Pressure
The fixed ball design provides good sealing performance even under high pressure, reducing seat wear and extending service life.
Suitable for Large-Diameter Pipelines
The Cast Steel Fixed Ball Valve is suitable for large-diameter pipelines where floating ball valves may experience sealing stability issues.
Wide Media Compatibility
PTFE, R-PTFE, PPL, and metal seats are suitable for media such as water, oil, gas, steam, and chemical fluids.
