Product - Side Entry Ball Valves

​​​​​​​​​​​​​​​Trunnion Mounted Ball valves

Our trunnion mounted side entry high performance ball valves, have a robust design and are engineered to meet International standards like API 6A, API 6D, ASME B16.34, ISO 17292 and others on request. The range contains both soft, metal or composite seats that can be configured with single or double piston effect to provide an effective double block and bleed (DB&B) in both closed and, on request, in open position.

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


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​​
