A solenoid-operated, electrically-variable, three-port, pressure-compensated, spool-type, 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.
The PV08-30 will regulate flow out of port 3 regardless of system working pressure. With an increasing current applied to the solenoid, the PV08-30 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 (dead-headed), a small bleed orifice is required at the priority port (port 3). Consult factory.
• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet armature construction.
