PV42-M30 Proportional Flow Control Cartridge, (PV42-M30)
A solenoid-operated, two-stage, three-port, pressure-compensated, spool-type, nor-mally 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.
Product Operation
The PV42-M30 will regulate flow out of port 3 regardless of system working pressure at 3 or at bypass port 2. Two priority flow ranges are provided for better resolution: Range A for priority flow up to 170 lpm/45 gpm, and Range B for priority flow up to 132 lpm/35 gpm. For either range, the input flow at 1 can be up to 225 lpm/60 gpm.
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 3 turns to reach start point. Continue another approximately 2 more turns to full shift. To Disen-gage: Turn counterclockwise approximately 5 turns to positive stop.
Product Features
• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
