Product advantages:
1. Precision casting valve body, fine appearance, no trachoma.
2. Valve wedge is burnished smoothly 3 times and polished 5 times to ensure the sealing porformance.
3. Valve stem is equipped with bearing to reduce friction.
4. Rubber coated PTFE packing seal, which can increase the elasticity and reduce the leakage of upper seal.
5. U-shaped sealing ring of the seat to ensure the strong conbation between valve seat and body.
6. Each valve will be tested shell and sealing pressure before leaving factory.
7. 250 μm epoxy coating, it can effectively prevent corrosion and rust.
8. The protection level of pneumatic actuator is IP67.
