Specification:ASME B 16.34
Semi-ball valve is a high performance valve we have developed with advanced technology.It is designed on the base of O type ball valve,which solves the difficulties of conveyance of "solid-liquid" and "solid-gas" two phase medium.
1.With straight through type valve body ,this valve can keep the fluid flow by linear when the valve fully opened,so it reduced less energy loss compared with other valves.
2.Easy to operate: As the valve disc moved away from valve seat without any contact,so it has smaller starting torque compared with O type ball valve and easy to operate.
3.Because of double eccentric structure design ,the semi-ball valve is perfectly sealed and can be closed tightly .
4.When the valve is closed ,the wedding force is able to remove the foreign materials ,therefore it has anti-scaling performance.
