Product features

Optimized lip seat design, automatic compensation for temperature and pressure changes, with safe and reliable sealing performance.
Onsite emergency repair remove the platen and replace the standard seat, without removing the platen and valve shaft, greatly reducing downtime, maintenance and replacement costs.
Two-way air tight seal, zero leakage, regardless of the medium flow direction, the valve to ensure sealing performance.
Bearing optimization extension design, surface hardening treatment,the valve shaft to provide maximum support, better high temperature resistance,corrosion and resistance to mechanical load deformation performance.
Standard with v-type PTFE valve shaft sealing system, ensure the valve opening and closing travel torque is lower, reduce the wear of various parts, and meet the international standards and specifications for emissions.
Valve shaft packing part does not need to be removed,easy to adjust, internal travel limit set, prevent clearance, reduce seat wear, prolong life.
Double stem design to increase valve flow capacity.
The company's high-performance butterfly valve has excellent performance, part of the working conditions can meet millions of switch operation.
