Accessory Valves
Low-High Valve
Low-High Valve Clamp with lower pressure to position parts then clamp with high pressure once sequence pressure has been met on the rest of the circuit. Common inlet port feeds both sequence and reducing valves in parallel. 5 (M8) manifold ports: 3x Inlet and 2x Outlet. 4 (G1/4) ports: 2 x Inlet, 2x Outlet. Use with single or double acting devices. Block includes standard Sequence and PRV cartridges. Can be sandwiched with a PRV/Sequence Combo block. Enough space is provided on the block to accommodate a Gauge for setup or troubleshooting. Recommended Filtration: 25 Micron (NOM) / 40 Micron (ABS) (minimum).
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 µm R a
