High Pressure Trunnion Ball Valve

Introducing our High Pressure Forged Steel Trunnion Ball Valve, sourced from a
reliable supplier. This valve is designed to meet API 6D, ASME B16.34, and DIN
3357 standards, making it suitable for high-pressure applications. Available in
sizes ranging from 2 to 48 inches, it is engineered for Class 1500 LB and PN250
pressure ratings. The valve is crafted from durable materials, including Carbon
Steel, Stainless Steel, and Alloy Steel, ensuring resilience in various
environments.

High-pressure forged steel ball valve is mainly used for long distance pipeline
transportation of oil and natural gas and urban gas pipeline system. Due to the
unique characteristics of the long distance pipeline valve, the design has fully
taken into account its ability to withstand pipeline stress, as well as safety,
weather resistance, long-term use of reliable sealing.

Forged Steel Trunnion Ball Valve is usually built by 3-piece body, suitable for
various kinds of pipelines, Class 150-4500 LB, PN16-PN720, JIS 5K-JIS 40K, is used
to cut off or turn on the pipeline medium, can be operated by worm gear, manual,
pneumatic actuator, electric driver, the connection type includes RF Flange, RTJ
Flange, Butt welding, Grayloc, etc.
