Pressure reducing valve (for steam, for air / gas) RP-9A type pressure reducing valve (for air / gas)
The face-to-face dimensions are the same as the old RP-2HA type pressure reducing valve, and the weight is reduced by about 40%.
Please refer to pages 21 and 22 of the catalog for the nominal diameter selection chart.

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.
