DAPV70-30 Proportional Flow Control Cartridge

DESCRIPTION

A solenoid-operated, electrically-variable, three-port, pressure-compensated, spooltype,normally closed when de-energized,proportional flow control valve. It can be used as a priority-type
flow regulator with pressure-compensated, regulated and bypass flow. It can also be used as a restrictive-type 2-way, pressure-compensated flow regulator when the bypass line (port 2) is
blocked.

OPERATION

DAPV70-30 will regulate flow out of port 3 regardless of system working pressure.With an increasing current applied to the solenoid, the PV70-30 will increase output flow.
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.
Operation of Manual Override: To Engage: Turn clockwise approximately 1 turn to reach start point. Continue another approximately 5 turns to full shift. To Disengage: Turn counterclockwise approximately 6 turns to positive stop.

FEATURES

● Excellent linearity and hysteresis..
● Hardened spool and cage for long life..
● Optional coil voltages and terminations..
● Efficient wet armature construction.
