REDUCED FLOW - Series RPV-R
2- and 3-Way, Normally Open, with threaded ports, 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 180°C) The valves can be mounted in any position without affecting operation |
