Please refer to page 14 of the catalog for the nominal diameter selection chart.
- Where to use
- Building equipmentFactory equipment
Major features
- Stable control is achieved by adopting a piston guide structure and a special seal ring.
- It can be used for a wide range of pressure and flow rates.
- The RP-6 type has an automatic lock mechanism (nominal diameter 15 to 80), and the pressure can be easily adjusted by manually operating the handle.
- 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.
