Check Valve
Dual Plate Flange Type Check Valve
Advantages
1. Close quickly before pump stop, eliminate the water hammer of the backflow medium, prevent the damage of the system shock.
2. Can be installed both vertical and horizontal.
3. Valve seat can be resilient material or metal material. It´s optional according to the medium.
4. Small Volume, light weight, need less space.
5. This valve should be install to the outlet side of the pump to prevent the backflow of the medium. This valve is one way flow direction.
6.This valve is tighly sealed, without leakage under the water pressure test. Safe and reliable in operation, High interference-resistance.
