Description
Technical Specifications
SPECS Trunnion mounted Ball Valve is used to cut off or connect the media in various pipelines of Class150 to Class2500. The valves made of different materials are suitable for various media such as water, steam, oil, liquefied gas, natural gas,coal gas, nitric acid, oxidizer, urea and etc. The driving modes include manual operation, worm and worm gear transmission,pneumatic operation and electric operation. The connection ends can be flange or butt welding.
Cast Steel Trunnion mounted Ball Valves allow easy and smooth operation at high line pressure. Carefully aligned bearings assist low torque operation. The ball is fixed in position but free to turn. All Casted Trunnion Ball Valves are with reliable high quality castings and fire safe design certified according to BS 6755, API607 & API 6FA. Meet all applicable ASME standards.
