Low-High Valve
Metric Accessory Valves
- 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)
* M8 Ports are counterbored for O-rings that are used in manifold mounting applications. Ø2.29 / 3.30 feed holes
** PRV set pressure range is: 10 – 60 bar with an inlet pressure of < 200 bar and 20 – 60 bar with an inlet pressure > 200 bar.
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 mµ Ra.
