Venn RD-20F Pressure Reducing Valve (for Water, Liquid, Air, and Gas)
Manufacturer: Venn Co., Ltd.
Model: RD-20F
Features
- The wetted part and spring case make of stainless steel and synthetic rubber, so they have excellent corrosion resistance.
- By adopting flow path studies and square springs, it is significantly smaller and lighter.
- The mounting position is free.
- Easy to maintain.
- It is liquid-gas and can used with a primary side pressure of 2.0 MPa.
