O-RING SEAT SEALS
LIFTING MECHANISMS


 




O-ring Seat Seals are available in the RO, RB, and all RL series valves. These Seals can be used up to the set pressure limit of the individual valve.


O-ring seat seals are the effective seat-leak stoppers, even in the severest application, saving valuable product and maintenance costs. Reyco offers a complete series of safety relief valves with resilient seats designed to meet the increasing demands for maximum tightness.

The Reyco O-ring Seat Seat assures maximum tightness at pressures closer to the critical set
pressure than is possible in a standard metal-to-metat seat valve.

Reyco's unique O-Ring Seat Seal design features spring loading on the disc seat, not on either the O-ring, itself, or on the O-ring retaining plate. This feature limits seal distortion --chiefly under heavy spring load or reclosure impact -- which occurs in a valve using the O-ring retainer as a seat. This patented Reyco design locates the O-ring seat on the inside of the seat diameter, thus barring the fluid media from the metal-to-metal
seat surfaces and minimizing corrosion. It also permits O-ring seat seals to be used up to the maximum pressure limit of each valve series. In the event of O-ring damage, the optically smooth, lapped seats provide the required commercial tightness standard of metal-to-metal seats until replacement is possible.

Consider selecting an O-ring seat seal to resolve the following problems where metal-to metal seated valves can involve leakage:


1) LEAKAGE DUE TO CORROSION

Corrosive fluids may erode sealing surfaces and cause damaging leakage. Reyco O-ring Seat Seal Safety Relief Valves resist such corrosive action, thanks to the proper use of O-ring materials which seal against leakage and shield and protect the valve's finely machine lapped, metal-to-metal surfaces.
