RP-9A - VAN GIẢM ÁP DÙNG CHO KHÍ AIR VENN NHẬT
RP-9A type pressure reducing valve (for air / gas)

It is a pilot type pressure reducing valve used for high pressure air and gas, and is a sister model of the RP-9, 10, 11 type steam pressure reducing valve.
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.
