RD-31N, 32N Type Pressure-Reducing Valve, Heisei

RD-31N, 32N Type Pressure-Reducing Valve, Heisei

Direct-acting general-purpose products (made of bronze, medium capacity) for use in construction equipment, factory equipment, etc.

[Features]
- Serves as a bronze water-pressure reducing valve meeting rust-water prevention needs.
- We combine our pressure-reduction technology with high controllability, reliability and user-friendliness, eliminating rust generation from pipe joints and across the flow path.
- Heisei provides reliable countermeasures for rusty water, used in building facilities, house facilities, plant facilities, boiler water supply, etc.
- Measures to prevent rusty water in normal state: Bronze body + pipe-end core to prevent rusty water.
- Low-noise design.
- Water does not leak outside if the diaphragm is damaged.
- Built-in strainer.
- (Nominal diameter of 50 or less 40 mesh equivalent) Smaller approximately 50% later than FC-made conventional parts.
