    Sequence Valves (Series Mounted)

    Sequence Valves (Series Mounted)

    Power Workholding

    7250 psi max

    Use 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). The series-mounted version shown here is used for multi-stage sequencing (2 to 6 sequence valves can be mounted in series, with only one input line). Also available in a stand-alone version with standard fittings, and a manifold-mounted version.

    Choice of two trigger-pressure ranges:

    Normal Range (1500 to 6500 psi)
    Low Range (150 to 2200 psi)

    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

    Choose normal-range model instead of low range whenever possible. Normal-range version provides a wider adjustment range, especially important when used with an Air Power Unit, which has a 2200-psi minimum operating pressure. For multi-stage sequencing, set trigger pressures in steps of at least 750 psi (normal range) or 375 psi (low range).

    Mounting & Fluid Supply

    Use one input valve and up to five series valves. Only one pressure connection is required (to the input valve's P port). The other valves are connected by an internal passage, sealed with O-rings between each valve (O-rings furnished). Two connecting bolts are required to fasten valves together (order separately). 1/4" BSPP ports. Mount in any position, horizontal or vertical. Do not use NPT fittings.
