DAFR10-39 Flow Regulator, Pressure Compensated
DESCRIPTION
A screw-in, cartridge-style, adjustable orifice, pressure-compensated, manuallyoperated,bypass-type hydraulic flow regulating valve. It can be used as a priority-type flow regulator or a restrictive-type 2-way flow regulator when the bypass port (port 2 )is blocked.
OPERATION
The DAFR10-39 maintains a constant flow rate from 3 regardless of load pressure changes in the system downstream of 3, or in the bypass leg at 2 . Reverse flow ( 3 to 1 ) bypasses the control orifice. The regulated flow increases from closed to fully open, with counter-clockwise rotation of the knob.
Note: When used as a bypass flow control in applications where the priority flow port will be blocked by external valving, bypass pressure drop will increase unless a small amount of leakage is provided for the priority port. Consult factory.
FEATURES
● Bypass port 2 may be fully pressurized.
● Fine low-torque adjustment.
● Hardened parts for long life.
● Quiet, modulated response.
● Industry common cavity.
