Rexroth Type 'S' Relay Valves

Check up to five results to perform an action.


Features
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.
