REDUCED FLOW - Series RPV-R

2- and 3-Way, Normally Closed, with flanges, PN32, DN 8 - 40

 

FEATURES

Valves with reduced flow rate. More compact and cheaper than the standard valves series RPV.

Ruggedly built valve, particularly recommended for use with steam, oil, superheated water, corrosive fluids and non-flammable gas

Seat rings, packing and piston seals can be easily exchanged.

Replacing a piston seal is considerably easier and quicker then exchanging a diaphragm on conventional diaphragm valves

Enclosed pistons, seals and springs are protected from dirt

High-performance, self-adjusting, spring-loaded, maintenance-free packing, resistant to thermal shock

Vacuum operation

Stainless steel body

Allowable backpressure: up to 32 bar

Valve for use at high ambient temperatures (up to 180C)

The valves can be mounted in any position without affecting operation
