1. The bidirectional flow double flange hard seal BUTTERFLY VALVE is a newly designed patented product. It is the first application in China.
2. With the advance of Short length, small size, simple structure, high precision seal.
3. Double curve designed sealing surface. Once valve opened, sealing surface serperated, once valve closed, valve sealed. Low opening torque, easy to open and close.
4. This valve can withstand high back pressure, to avoid medium back-flow, play a role of Check Valve. Suitable to be installed at the exit of pump.
5. The sealing surface adopts alloy steel, stainless steel, hard alloy, with the capacity of anti abrasive. Long Service life.
6. Resistant to high temperature and pressure, anti-corrosion
7. Manual, Pneumatic, Electric and hydraulic actuator available.
