Venn RD-20FN type pressure reducing valve (for water / liquid, air / gas)

Manufacturer: Venn Co., Ltd.
Model: RD-20FN
Specifications
- 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.
