Low-High Valve
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 (SAE 2) manifold ports: 3x Inlet and 2x Outlet
- 4 (SAE 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)
* SAE 2 Ports are counterbored for O-rings that are used in manifold mounting applications. Ø .09/.15 Feed Holes.
** PRV Set Pressure Range is: 150 – 900 PSI with an inlet pressure of <3,000 PSI, 300 – 900 PSI with an inlet pressure of >3,000 PSI
Order a Filter Plate to protect valve from debris, 70-8420-07.
For proper sealing, mating surface must be flat within 0.003 in. with a maximum 63 µ in. R surface finish.
