Item Information

Parker’s pilot operated sequence valve with a built-in reverse check reduces manifold space, complexity, and the number of components in a hydraulic system. These valves can work with pressures up to 420 bar (6000 psi) and flows up to 70 lpm (18.5 gpm) and allow for multiple double acting functions to be operated with a single directional control valve. Parker’s pilot operated sequence valve with a built-in reverse check can be utilized in several applications, but is ideal for load control and clamping or press applications within mobile and industrial markets.

Markets:
• 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
• Load holding
• Actuator control
• Motor control

Additional Technical Insight:
B04D3 is an internally piloted and externally drained sequence valve with an integrated reverse free flow check valve.  When pressure is below the sequence setting the valve is normally closed.  Once the pressure setting is reached the valve is internally piloted open allowing flow to a secondary branch of the circuit.  Flow from the secondary branch is allowed to free flow back to the primary branch via the reverse flow check.  The external drain should be plumbed directly back to tank to prevent downstream pressure from adding to the sequence setting.  Two adjustable pressure ranges are standard for 3000 or 6000 PSI maximum operating pressures, and each version is capable of flows up to 32 GPM.   Screw, knob, and tamper-resistant adjustment options are available.

Combining a sequencing function and reverse flow check into a single size 10 cartridge reduces manifold space, complexity and the number of components.  The integrated check valve reduces internal drillings and can also allow for multiple double acting functions to be operated with a single directional control valve.  Parker’s B04D3 offers design flexibility that can be utilized in many applications including:  Clamp and Drill, Machine Tools, Presses, Power Units, Material Handling, Construction, and Agriculture.
