Reliability
Automatically sustains pressure directed by the pilot line on a 1 to 1 ratio (optional ratios shown below). The balanced internal valve functions to relieve excess pressure, or to maintain pressure against demand. Rubber seated valves provide zero leakage.
Installation Versatility
Operates in any position. May be supported by piping alone or by a mounting bracket. The IN and OUT ports are plainly marked on the body.
Ease of Maintenance
The valve may be serviced without disturbing line connections. All parts are accessible by removing top cover. No special tools are required.
Large Capacity
Designed with minimum valving to provide maximum flow (see graph).
Modern Construction
All materials are corrosion resistant. The sturdy die cast body contains wrench flats for ease of installation. Ports have dry seal pipe threads (suitable with standard pipe thread).
Positive Seals
Packing rings are located at all critical points in the assembly to eliminate internal and external leakage.
Application
The "S" Relay Valve is a pilot-operated, 3-way, pneumatic pressure control valve with open exhaust. The large capacity of this valve makes it an ideal volume booster. It receives pressure signals from a remote control valve and repeats this pressure with a greater rate of flow to the component being controlled. The valve serves to speed response time between sending and receiving stations in a pneumatic circuit which involves long piping runs or branch circuits. Where the controlled component is not in a readily accessible location, remote piloting provides a solution.
