Venn RP-9A type pressure reducing valve for air / gas
Manufacturer: Venn Co., Ltd.
Model: RP-9A type
Features
- This is a pilot-type pressure reducing valve for high-pressure air and gas.
- In addition, it is a sister model of the RP-9, RP-10, and RP-11 steam pressure reducing valves.
- Moreover, the face-to-face dimensions match the former RP-2HA pressure reducing valve.
- At the same time, the weight is reduced by about 40%.
- For nominal diameter selection, please refer to pages 21 and 22 of the catalog.
