Venn Co.
Venn RD-20 Type Pressure Reducing valve
Manufacturer: Venn Co., Ltd.
Model: RD-20
Features
Stainless steel and synthetic rubber use for the wetted parts and spring case, so they have excellent corrosion resistance.
By examining the flow path and adopting square springs, etc., the size and weight have significantly reduced.
The mounting posture is free.
Easy to maintain.
It can use for both liquid and gas at a primary pressure of 2.0 MPa.
