VENN – RD-31N Pressure Reducing Valve
Calm is a bronze water pressure reducing valve that meets the demands of the times as a [trump card for measures against red water]. [Quiet], which combines the technologies of our water pressure reducing valve, which has already received high praise, and pursues controllability, reliability, and ease of use, is a source of rust, especially from the flow path including the pipe joint. Is lost. [Quiet], which is becoming more and more popular as a countermeasure against red water, is used for building equipment, housing equipment, factory equipment, boiler water supply, etc.
Major features
- Calm flow red water countermeasures: Main body bronze + pipe end core prevents red water.
- It is a low noise design.
- It is about 50% smaller and lighter than the conventional FC product.
- Even if the diaphragm is damaged, water will not leak to the outside.
- It has a built-in strainer. (Nominal diameter 50 or less)
