RP-11 type pressure reducing valve (for steam)
A pilot type pressure reducing valve is used to reduce the pressure of high-pressure steam.
With a maximum decompression ratio of 20: 1, stable operation is achieved even at high differential pressures.
The face-to-face dimensions are the same as the old RP-2H pressure reducing valve, and the weight is reduced by about 40%.
