Pilot-Operated Sequence Valves
Brand: Parker HannifinParker’s selection of pilot operated sequence valves provide superior stability and are designed for sequenced applications with pressures up to 380 bar (5500 psi) and flows up to 152 lpm (40 gpm) in a variety of sizes.
The variety of pressure adjustment styles and piloted or vented controls makes these valves an ideal solution for controlling multiple circuit sections that operate at different pressure settings.
Normally-open and normally-closed valves are available in a 2 position 2-way configuration and can be either internally or externally drained depending on application needs.
These pilot operated sequence valves can be used within clamping circuits or high/low system applications within several industrial and mobile markets.
Features- High pressure and flow capacity
- Internal screens for pilot spring protection
- Low profile designs
- Hardened, precision ground parts for durability
- All external parts zinc plated
