Cast Steel Trunnion Mounted Ball Valve

Description

The Cast Steel Fixed (Trunnion Mounted) Ball Valve has a ball supported by upper and lower trunnions, so line pressure is carried by the bearings instead of the seats. This keeps operating torque low in large sizes and high pressures, while spring-loaded seats give reliable sealing for oil and gas pipelines.

Technical Specifications:

• Pressure Class: PN16 – PN100
• Size Range: DN50 – DN600
• Applicable Medium: Oil, natural gas, water, petroleum products
• Operating Temperature: -29°C to 180°C (seat dependent)

Main Parts and Materials:

Key Product Features:

1. Trunnion Support: Low torque even at high pressure and large size.
2. Spring-Loaded Seats: Tight seal at low and high pressure.
3. Double Block & Bleed: Seals on both sides with body cavity relief.
4. Fire-Safe & Anti-Static: Safety design for hydrocarbon service.
5. Emergency Sealant Injection: Seat sealing can be restored in service.

Applications:

Ideal for Oil & Gas Pipelines, Gas Stations, Petrochemical Plants, and City Gas Networks. Specifically suited for large, high-pressure isolation duties.
