PFR70-33x-E Proportional Flow Regulator, N.C., (PFR70-33x-E)
A pressure-compensated electrically-variable two-port flow regulator that is normally closed when de-energized. This combination valve uses a PV70-33x proportional cartridge and an EC10-30 compensator.
Product Operation
This proportional valve/compensator package will regulate flow out of port ➁, regardless of system working pressure. With an increasing current applied to the
solenoid, the PFR70-33x-E will increase output flow.
Product Features
• Excellent linearity and hysteresis.
• Optional control orifice sizes.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Effi cient wet armature construction.
