Pressure Compensated Proportional Poppet Valves

Screw-in electrically adjustable hydraulic cartridge valves giving the operator nearly infinite adjustment control and flexibility. Parker’s FAPC series offers low leak reliable proportional control.

Полное описание продукта

Parker Hydraulic Cartridge Systems Division combines Parker’s precision ground poppet and SuperCoil technology with a newly patented integral compensator design, bringing you a flow control product with best in class repeatability and a truly exceptional level of control.

In conditions of varying load, the FAPC series maintains predictable and repeatable performance through the introduction of our new fully integrated compensator. Built directly into the FAPC series valves, the innovative new compensator maintains a tight seal for load holding without any requirement for additional sealing. When open, the compensator responds to changing load conditions independently. With no seal friction to overcome, the FAPC valve maintains the repeatable and predictable performance customers can rely on. This additional feature eliminates the need for complex programming algorithms, and any requirement for an external compensator to improve the operator’s control.

• Excellent metering capability and control throughout the full flow range
• Reduced drift
• Low leak control (less than 5 dpm)
• Modular solution to applied problem
• Low leak compensator, requiring no additional seals, results in very low hysteresis (< 10%)
• Maintains constant flow regardless of load condition
• Patented integrated low leak compensator

How it works:
The FAPC utilizes a control current to proportionally raise and lower a poppet creating a variable orifice allowing flow to pass through from the inlet to the outlet. There is also a low leak integral compensator that responds to load changes in the hydraulic circuit by varying the outlet orifice, metering the flow rate that can be passed through and maintaining constant flow independent of load conditions.

The fully compensated FAPC is rated to flows up to 115 LPM (22 GPM).

Common markets and applications include the aerial markets (boom raise/lower), fork lift (lift/lower) and vehicle lift.
