Accessory Valves
Sequence Valve
DON’T DON’T
Sequence Valve Control the timing of fixture devices. Specialized construction resists corrosion which can cause other styles to “misfire.” Direct acting poppet style construction. Manifold mountable. Cartridge may be installed directly into your manifold. Two-port design eliminates need for third fluid line to drain bypass flow (internal leakage) back to system reservoir. True sequence design allows full system pressure downstream of valve after opening. n Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (minimum).

NOTE: When using multiple sequence valves. For pressure set range 300 to 900 psi
*SAE 2 Ports are counterbored for o-rings that are used in manifold mounting applications. .09/ .15 FEED HOLES Excess flow voids warranty.
For proper sealing, mating surface should be flat to 0.003 in. with a maximum 63 R a µin. surface finish. a 100 psi spread between pressures is recommended. For pressure set range 750 to 5000 psi a 500 psi spread between pressures is recommended.
