Check Valve Angle Type

Check Valve series products are mainly used in the pipeline which only allows the medium to flow in one direction and prevents the reverse flow. Under the action of the fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the valve disc acts on the valve seat by the fluid pressure and the self weight of the valve disc, thus cutting off the flow. It can be used to prevent the back flow of medium on various pipelines of refrigeration system. The products are mainly divided into straight check valve and angle check valve.

Applicable medium: CO2,R12, R22, R502, R134a, R404A, r507, R717, etc
