Venn RHU-1 Door-to-door Reducing Valve Unit (for water and hot water)
Manufacturer: Venn Co., Ltd.
Model: RHU-1
Features
- It supports labor-saving installation by combining door-to-door pressure reducing valves into a single unit.
- In addition, the rubber parts make of FKM for improved durability.
- Moreover, it operates reliably from low to high differential pressure.
- As a result, water pressure testing is possible with the pressure reducing valve installed.
