ARI-REYCO R SERIES ANSI-Full Nozzle-Safety Relief Valve with flanges - closed bonnet -closed lifting device - acc. to API 526
Accurate response, flip-over plug, optimal plug guiding – up to 6000 psi (414 bar)!
Powerful: suitable for oil and gas processing (REYCO®).
Flexible: optionally available in Monel, Duplex, Super Duplex or Hastelloy.
Simple handling: easy to service due to the flip-over plug (double sided sealing system).
Durable: increased service life due to the corrosionresistant bellows seals made of Inconel 625; the bellows also provides backpressure compensation as standard.
Reliable and resistant: precise repeatability of the set pressure and increased service life due to the accurately guided nozzle (nozzle thread close to the seat).
Reliable: high level of reliability due to the optimal guiding of the plug on the seat (two-piece stem).
Flexible: multifunctional conversion in a few simple steps thanks to the modular system (standardised trim).
Identical trim irrespective of the medium (steam, gases, liquids).
Flexible / simple handling: broad array of applications due to the standardised O-ring soft sealing plug.
Simple handling: identical nozzle ring for each orifice size (code letters).
REYCO®: certified safety due to EC type examination (module B), quality assurance system (module D) and declaration of conformity acc. to PED 2014/68/EU.
Now up to DN 250 in stainless steel also with stainless steel bellows
