Roemheld CLR-2953-111-V | 435 to 5500 PSI Range Pressure-Reducing Valve

Roemheld Standard Fittings

Pressure-Reducing Valves allow operating a single clamp, or group of clamps, at a lower pressure than the rest of the fixture. These valves can be used to finely adjust the clamping force of selected components while keeping others at full pressure. Great new design can be used on pallet fixtures disconnected from a power source, since no return line is needed for operation. Zero-leakage poppet design. The version is used for in-line mounting with standard fittings and exposed fluid lines. Also available in a manifold-mounted version for mounting on flat surfaces, and a threaded-body version for cartridge-type manifold mounting.

Operation

To set up initially, turn the adjustment screw on top until the desired downstream pressure is achieved. During normal operation, Pressure-Reducing Valve automatically shuts off downstream flow when system pressure reaches the set pressure. As long as the system remains connected to the power source, the valve will reopen if additional fluid is required to maintain downstream pressure.

Design Considerations

When using this valve in series with other valves such as Clamping Valves, Sequence Valves, and Flow-Control Valves, the Pressure-Reducing Valve must be the one closest to the reduced-pressure clamps. When a Pressure-Reducing Valve is used in an uncoupled system, no regulation of downstream pressure is possible after disconnection, so we strongly recommend adding a Pressure-Relief Valve to guard against unwanted pressure increases caused by temperature increases, etc. (must be added to the downstream side).

Mounting & Fluid Supply

Mount in-line. Fasten valve to fixture using a 5/16 or M8 cap screw if desired. Mount in any position, horizontal or vertical. Two 1/4" BSPP ports.
