1.Labor-saving operation as the ball is supported by dual bearings to reduce friction;

2.PTFE unisexual material sealing ring is embedded in the stainless steel valve seat, and the end of the metal valve seat is equipped with a spring to ensure sufficient pre-tightening force of the sealing ring;

3.Fireproof sealing ring is set between the ball and the valve seat to form a metal-to-metal seal in case of fire according to API6FA and API607 standards;

4.Drain holes are set up and down the valve body to check whether the valve seat is leaking;

5.Scotch yoke pneumatic actuators are engineered for reliable on/off, direct acting, and spring return valve control.
