TECHNICAL SPECIFICATIONS

TRUNNION BALL VALVES

TV SERIES

MAIN TECHNICAL CHARACTERISTICS

The trunnion hinged ball side entry design that we use, gives more facility to handle, allowing to reduce the torque and the worn out of seats. Is available soft and metal seated valves. Double o-rings to improve sealing. Anti-static (steel spring or ball) in according to API6D, guarantees electrical continuity between the parts (ball-stem or stem-gland flange). Stem extension or Gland Flange extension on request. Operation available with lever, gear or available with Actuator pneumatic or electric.
