Side Entry Flanged Forging Ball Valve Trunnion Type With Electric Actuator
Key features
Soft, metal or composite seated
Two or three piece body
Bi-directional tight shut-off
Double block & bleed
Fire safe and fire tested
Bolted or fully welded construction
Low operating torque design
Wide range of materials and sizes
Trunnion mounted with spring energized seats
Anti-blowout stem design
Suitable for above ground or below ground installation
Benefits
The use of forgings and the independent spring or bellows loaded floating seats which are always in contact with the ball, make these valves the preferred solution for various demanding applications like Cryogenic, High Temperature, Low Emission and ESD / HIPPS.
Suitable for use in the most severe services such as scraper launcher and receiver and hot tapping
Valves can be equipped with bellow seals, steam flushing ports and protected bearings, to cope with medium/high amounts of solids like tar sands or catalysts
Approved by the major end users, licensors and contractors and are designed to meet SIL3 requirements according to IEC 61508
The double or triple stem seal design (with lip seals or o-rings or optionally with leak off chambers for predictive maintenance) mean that the valves meet and exceed the most stringent Low Fugitive Emissions Norms (ISO 15848) making our valves suitable to handle toxic or lethal fluid services
Spring or floating seats which are always in contact with the ball provide an effective tight seal even at low differential pressure
