Trunnion ball valves

Two-axis ball belongs to the high-pressure Trunnion ball valve  series, the compact features of the structure of the Instrument needle valves, appearance, maximum flow rate, low operating torque, enabling 2-way and 3-way path, enabling the panel installation, enabling pneumatic and electric actuators, important about seeking law instructions, ball unused for some time may have a higher initial torque to open all series ball valves are bi-directional test using nitrogen at the factory. The maximum allowable leakage test pressure the ball for the simple task can not be detected leaks.
