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). Use in multiples for multi-stage sequencing. The version shown here is used for in-line mounting with standard fittings and exposed fluid lines. Also available in a manifold-mounted version, and a series-mounted version that is ideal for multi-stage sequencing.
Choice of two trigger-pressure ranges:
Normal Range (1500 to 6500 psi)
Low Range (150 to 2200 psi)
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).
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).
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. Do not use NPT fittings.
