Roemheld CLR-420-V | 150 to 2200 PSI Range Low Sequence Valve

Sequence Valves

7250 psi maxUse to automatically sequence positioning, clamping, and supporting functions as system pressure increases. Sequence Valves prevent fluid flow to a portion of the fixture until a predetermined trigger pressure is achieved (easily adjustable). Use in multiples for multi-stage sequencing. The version shown here is used for in-line mounting with standard fittings and exposed fluid lines.

Operation

To set up initially, turn the adjustment screw on top until the desired trigger pressure is achieved. During normal operation, Sequence Valve opens automatically when system pressure reaches the set trigger pressure. After the valve opens, system pressure rises uniformly on both upstream and downstream sides (no pressure drop upstream when the valve opens).

Design Considerations

To set up initially, turn the adjustment screw on top until the desired trigger pressure is achieved. During normal operation, Sequence Valve opens automatically when system pressure reaches the set trigger pressure. After the valve opens, system pressure rises uniformly on both upstream and downstream sides (no pressure drop upstream when the valve opens).

Mounting & Fluid Supply

Mount in-line. Fasten valve to fixture using two #10 or M5 cap screws if desired. Mount in any position, horizontal or vertical. Two 1/4" BSPP ports.
