Pressure reducing valve (for water / liquid / door-to-door water supply), constant flow valve, water hammer preventer RD-36F type pressure reducing valve (for water / hot water / air)
With improved controllability, reliability, and corrosion resistance, it can be used in plants.
Major features
- It can also be used for expulsion of red water and stainless steel piping with the main body SCS.
- 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.
- The pressure gauge can be attached directly to the main body. (Secondary side only)

- We also manufacture a pressure gauge attachment only on the secondary side. (The maximum scale of the pressure gauge is the secondary adjustment pressure range L (0.6MPa) and H (1.6MPa).)
- We also manufacture waterworks law performance standard compliant products (RD-35N, 35FN, 36N, 36FN types). (Certification registration number: E-442)
- We also manufacture RoHS compliant products.
- For the RD-35,35F type, we also manufacture the RD-35T, 35FT type, which is compatible with temporary cleaning steam (maximum operating temperature of 130 ° C) in beer and drinking water factories.

Frequently Asked Questions and Explanations
Please tell me how to adjust the pressure. (There is a video in the answer details)
Please see the video of the pressure adjustment method from the answer details.
What is the useful life (the number of years recommended for replacement)?
The useful life of the main unit is about 8 years, but it depends on the usage conditions and environment.
Is it possible to reduce the hydrostatic pressure (without flowing water)?
When no water is flowing (flow rate 0), the valve is closed and the secondary side holds the set pressure.
What happens if the minimum flow rate or minimum differential pressure is exceeded?
If the conditions are outside the specified range, control will be lost and operation will become unstable.
