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 or can be open via an integral reverse flow check valve (optional).

Markets:
• Industrial

Features/Benefits:
• Excellent fine adjustment - precise pressure control
• Adjustable response time - for optimum adaption to the application
• Flexible, versatile mounting in any orientation - makes installation easy
• Subplate mounting according to ISO 6263 - for quick integration
• Short delivery time -no warehousing necessary
• Closed in neutral position
• Optional reverse flow check valve
• 2 sizes, NG10 (3/8“), NG16 (3/4“)

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
