Venn RD-37 Pressure Reducing Valve (for Water, Hot Water, Air, and Liquid)
Manufacturer: Venn Co., Ltd.
Model: RD-37
Features
- The spring and spring case also make of SUS, which offers excellent corrosion resistance.
- In addition, it features a low-noise design.
- Moreover, even if the diaphragm damages, water will not leak outside.
- Furthermore, the mounting position is flexible.
- As a result, installation is easy.
- You can also install a pressure gauge directly on the body.
- This applies to the secondary side only.
