Product Features

1. This valve is a new type of throttling, cut-off and venting products. The valve adopts cage shaped fan throttling, which has the characteristics of multi-stage throttling effect, obvious throttling effect, reliable sealing and convenient operation and maintenance.
2. The valve adopts double seal (hard and soft seal) to make the seal reliable. The hard alloy cover can be more resistant to air flow erosion and wear resistance. The double seal can achieve zero leakage under the condition of high pressure gas medium. The valve has a long service life.
3. The sealing surface of the valve seat adopts taper sealing, which is conducive to cleaning the dirt attached to the sealing surface.
