2-Way Variable Flow Control Valve - Series 2F1C

Parker's proven 2-way flow control valves series 2F1C in size NG10 and NG16 feature a constant, pressure, temperature and viscosity compensated flow from port A to port B. Due to their sophisticated design, they enable a linear cylinder movement by suppressing starting jumps. The counter direction is blocked (standard) or can be open via an integral reverse flow check valve (optional).

Applications:
Suitable for general hydraulic applications

Function:
The compensator spool is located in front of the metering spool. The metering spool is closed in the neutral position to avoid unintended initial actuator  motion. The oil flow to open the metering spool has to pass a needle valve. The needle valve can be adjusted from the front panel to set the response time of the 2F1C. The metering spool is adjusted by the main control knob.

The key lock has three positions:
Lock: Adjustment is locked
Adjust: Full adjustment is permitted
Trim: Fine adjustment of ±5 % is possible
