Venn RD-8 type pressure reducing valve for air / gas

Manufacturer: Venn Co., Ltd.
Model: RD-8 type
Features
- Because it is a direct-acting type, it provides stable control from small to large flow rates.
- As a result, it is used to reduce pressure in various air lines and high-pressure gas lines.
- In addition, the valve body has a balanced structure.
- Therefore, changes in primary pressure have only a small effect on the secondary pressure.
