Sealant injection at stem position Sealant injection at seat position (injection valve + check valve) Anti-Blowout Design For the sake of safety, the stem must be designed with a blow-out proof device to prevent the stem from being blown out by the internal pressure when the packing gland or actuator yoke is removed. Anti-static Device In order to avoid accidents arising from static accumulation, all metal ball valves are provided with an anti-static device at the body, the ball and the stem, so that the static electricity produced by the valve itself can be smoothly discharged out of the...
