DESCRIPTION:
The trunnion ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and harsh environment resistance have been specially considered during design, and are suitable for various corrosive and non-corrosive media.
DESIGN FEATURES:
Trunnion mounted ball valves meet all the requirements of API 6D as well as the other design codes; Minimum wall thickness comply with ASME B16.34. Valves are usually supplied with lever, gear,actuator or bare shaft as per customers’ request.
ISO5211 platform design is adopted for the convenience of installing the actuator
Double block and bleed function
Anti-blow-out stem design
The pressure balancing hole is provided on the steel ball
The body is provided with a device for cleaning the valve cavity
Automatic pressure relief function
Fireproof and anti static design
Sealant injection system for emergency seal
Multiple driving modes facilitate the realization of automatic control
Reliable stem seal and low operating torque, Metal hard seal seat is also available.
