Product characteristics
1. Adopting special moulding technology to make the sealing surface dense and good, plus V-PTFE packing combination, the valve achieves zero leakage.
2. The sphere and the valve stem are cast as a whole, which eliminates the possibility of the valve stem rushing out of the pressure parts due to the pressure change, and guarantees the safety in use fundamentally.
3. All-plastic lining technology is adopted, which is resistant to strong corrosion of medium.
