Features
Mosaic valve seat prevents seal ring from blowing out.
Installing ball into valve body by the upper for repairing Conveniently.
Integral valve body design, top mounted stem makes fixed support, flange structure.
Integral pivot fixed stem design,Double blocking discharging function.
High strength integral stem structure, ensure the accurate sphere location .Valve stem uses Blowout proof protection structure.
2 groups orings, with fireproof packing structure on the valve stem and low friction bearings, these can prevent leakage and corrosion effectively.

Because the corrugated nickel spring make nylon-sealed metal valve seat move to the ball, which makes valves have two-way sealing function at inlet and outlet.The superior performance standard nylon and PEEK seats ensure effective sealing in low-pressure condition.


Sealant injector design can inject sealant into the valve body in order to seal valve stem and seat in the state of emergency.Using the unique seat retractable technology , it can replace stem,seal ring, metal seat and corrugated spring without disassembly by reducing torque to the minimum so can operate easily.


The stem and body contact effectively with superior performance of anti-static electrical grounding device.Pre-set driving device platform and screw hole, it can install actuators at any time. when the seat burns or damages, the metal valve seat will compact sphere automatically, that will make minimum leakage between seat and body.
