DESCRIPTION

FR12-33X is a screw-in cartridge, adjustable orifice, pressure compensation, manual operation bypass flow control valve. It can be used as a priority type flow regulator or a restrictive type, 2-way, flow regulator when the bypass line (port 2) is blocked. 

 

OPERATION

The flow from port 3 remains unchanged and is not affected by the load pressure change of the downstream circuit of port 3 or bypass port 2. The reverse liquid flow (from port 3 to port 1) does not pass through the control orifice. Turn the handle counterclockwise to gradually increase the regulated flow from closed to fully open

Note: when used for bypass flow control and the priority oil port is closed by other locks, unless there is a small amount of leakage at the priority oil port, the bypass pressure drop will increase. Please contact the factory.

 

FEATURES:

l  Bypass port 2 may be fully pressurized.

l  Hardened steel parts for long life.

l  Quiet, modulated response.

l  Industry-common cavity.
