1. Characteristics of top-mounted ball valves.
Integral valve body design, top-mounted pivot fixed support, flange structure, integral pivot fixed club design, double blocking and venting function, high-strength integral club structure.
To ensure the precise positioning of the ball, the pivot adopts an anti-blowout protection structure, 2 sets of O-rings, plus a fireproof packing structure on the valve stem.
Effectively preventing leakage and corrosion, the low coefficient of friction bearing makes the nylon sealed metal seat move towards the ball due to the nickel corrugated spring.
Standard nylon and PEEK seats with inlet and outlet bi-directional sealing performance ensure effective sealant inlet design at low pressure, sealant can be inserted in emergency conditions, and unique seat retractable technology is used to seal the stem or seat.
*Replaceable clubs. The torque of the metal seat and corrugated spring of the valve stem sealing ring is reduced to a minimum, which is convenient for the valve to operate the ball rod and the valve body in effective contact, and the anti-static grounding equipment with superior performance presets the drive device platform and screw hole, and can be equipped with the fire protection function of the drive device at any time; When the seat burns out or is damaged, the metal seat automatically adheres to the ball, and there is a smaller leakage between the seat and the ball.
