Full Product Description

Parker’s kick-down pilot operated sequence valve provides fast responding and reliable performance for hydraulic circuits that require pressure to be eliminated once the max setting is achieved. These valves can work with pressures up to 420 bar (6000 psi) and flows up to 160 lpm (42 gpm) and can be considered a hydraulic fuse. Parker’s kick-down pilot operated sequence valve is intended for clamping or press within industrial markets, but can also be use in mobile applications such as when attachments are used with quick disconnects and a fixed displacement pump.

Markets:
• Agriculture
• Aerial
• Construction
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile

Features/Benefits:
• High pressure and flow capacity
• Integrated 250 micron screen
• Hardened, precision ground parts for durability
• All external parts zinc plated

Applications:
• Clamping
• Power units
• Attachments/implements with quick disconnects

Additional Technical Insight:
Unlike relief valves which will reset slightly below their pressure setting, Parker’s B04C3 Kick-Down sequence valve will continue to unload pump flow until its supply flow is completely stopped.  Two adjustable pressure ranges are standard for 3000 or 6000 PSI maximum operating pressures, and each version is capable of flows up to 42 GPM.   Screw, knob, and tamper-resistant adjustment options are available.

B04C3 pilot operated cartridges are normally closed, internally piloted and externally drained.   The external drain prevents downstream pressure from having an effect on the valve setting.  When inlet pressure at port 1 is lower than the valve’s setting, flow is not allowed to exit port 2.  Once the pressure setting is reached, flow from port 1 is unloaded to port 2.  The valve does not reset and close until flow is completely removed from port 1.  Staying open after the setting is reached creates a requirement for an operator or the system controls to take steps of removing flow before the valve can stop unloading the pump.  Functioning in a manner similar to a fuse can provide additional over-pressurization protection and can also help to detect unusual high pressure machine conditions.
