A pressure-compensated electrically-variable three-port flow regulator that is a priority (bypass) type control. This combination valve uses a PV70-33x proportional cartridge and an EC12-40 compensator.
The PFR70-33x-J series will bypass all flow when de-energized at the pressure
compensator spring value. When energized, 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.
• 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.
Operating Pressure: 207 bar (3000 psi)
Pressure Rise: Pressure at ➀ begins to rise higher than the compensating pressure differential when bypass flow exceeds 41.6 lpm (11 gpm).
Internal Leakage: 410 cc/min. (25 cu. in./min.) fully closed at 207 bar (3000 psi) out port ➁
Electrical: 2 standard voltage ratings
