Parker’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.

Additional Technical Insight:
SVH081, SVH101, and SVH161 pilot operated sequence valves are internally piloted and externally drained.  All three versions are normally closed spool-type valves that prevent flow from passing through the valve until the adjustable pressure setting is reached.  When the inlet pressure exceeds the sequence setting the valve is internally piloted open allowing flow downstream to a secondary function.  An external drain port plumbed directly to tank ensures that downstream pressure does not affect the pressure setting.  Clamp and machine, or unlock and dump, are typical applications since they require one function to happen before another one.

SVH102 and SVH162 are externally piloted and internally drained sequence valves.  Both are normally closed and prevent flow from passing through the valve when the pilot pressure is below the pressure setting.  When the external pilot source exceeds the adjustable pressure setting, the valve opens allowing flow to go downstream.  Back pressure on the downstream port is added to the valve setting due to the internal drain, therefore it is most common to connect the sequenced port to tank.  High-Low Pump Unloading is a common application.

SVCH101 is an inline mounted combination of an internally piloted, externally drained sequence valve and a reverse flow check.  An SVH101 sequence valve and a CVH103 check valve are incorporated into a single body with SAE-8 work ports and an SAE-6 drain.
