Product Introduction: Manual ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as no friction on the switch, less wear on the seal, and small opening and closing torque. This can reduce the specifications of the equipped actuator. Equipped with a multi turn electric actuator, it can achie1

Sealing characteristics of valve seats: The valve seats of floating ball valves are mostly made of polymer materials such as polytetrafluoroethylene and para polystyrene, which have good sealing performance, but the materials are relatively soft. Due to the softness of the material but the need to achieve a certain sealing pressure ratio, it is nec1
