2 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 valve. The anti-static device is composed of the metal ball and the spring. Fire Safe Design The valve is designed to have double-sealing. The first seal is the soft seal and the second seal is the metal seal. In case of fire, the soft seal is burnt and the metal seal will play its role in reducing medium leakage. The fire resistance design of valves is qualified by fire testing in accordance with API 607, API 6FA and ISO 10497, and meets the fire-safe requirements in API 607 and API 6FA. One Piece Body Type Ball Valve Summery The one-piece body ball valve is designed as reduced bore & floating ball structures. The body is overall casted without bonnet so that there's no leakege point on the body.
