Downstream pressure reducer-stabilizer for high pressure, pn64
The direct acting pressure reducing valve Mod. RDA reduces and stabilizes the downstream pressure to a
constant value, regardless of flow rate variations. It can be used for water, air and fluids in general up to a
temperature of 70° C and a maximum pressure of 64 bar.
Technical features and benefits
Flanged version DN 50-150 PN 64 rated.
Ductile cast iron cap and body in electro-welded steel, piston and mobile block in stainless steel.
Upstream and downstream pressure balanced, to stabilize the downstream pressure to a pre-set (and adjustable) value regardless of upstream pressure variations without creating unwanted upsurges.
Innovative self cleaning piston technology (patent pending) to improve performances reducing maintenance operations.
Mobile block composed of three components in gun metal/stainless steel obtained by CNC to ensure the maximum accuracy and sliding precision, this is to avoid friction and unexpected leakage.
Upstream and downstream pressure outlets for gauges.
Large expansion chamber and materials providing an excellent resistance to cavitation and long lasting performances.
Epoxy powder applied using FBT technology.
Water distribution systems for high pressure ratio.
Industry and cooling systems.
Dams and power plants.
