Pressure reducing valve (for steam, for air / gas) RP-7 type pressure reducing valve (for steam)
It is compact and lightweight (MAX.50%, compared to our company) and can be incorporated into equipment.
- Where to use
- Food equipmentDisinfection equipmentCleaning equipment
Major features
- By adopting a piston guide structure and a special seal ring, stable control is performed from a small flow rate to a rated flow rate.
- Pressure adjustment is easy by operating the manual handle with an automatic lock mechanism.
- It is a compact design.

Frequently Asked Questions and Explanations
Is there a leak in the steam pressure reducing valve?
The allowable leakage amount is stated in the specifications of each product.
Does the fluid flow without pressure adjustment?
It doesn't flow. It will flow normally only after adjusting the pressure.
How should I perform maintenance and inspection of the steam pressure reducing valve?
We perform regular maintenance once a year as a guide. Please refer to the instruction manual for details.
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.
