PV70-35 Valve

PV70-35 Valve symbol
A solenoid-operated, spool-type, normally open, proportional flow control valve
designed for use with a pressure compensator to function as a proportional flow regulator.

The PV70-35 provides regulated flow from port 2 to port 3. Port 1 should be plugged.
Flow is inversely proportional to current applied to solenoid.

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 until positive stop is found.

• Choice of several regulated flow ranges
• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage-interchangeable.
• Unitized, molded coil design.
• Coil waterproofing standard.
• Manual Override option.

   Bypass (Port 2) 207 bar (3000 psi)
Proof Pressure: 345 bar (5000 psi)
Burst Pressure: (896 bar (13,000 psi)
Flow Rating: Range A - 0 to 45.4 lpm (0 to14 gpm) Range B - 0 to 41.6 lpm (0 to 11 gpm);
   Range C - 0 to 18.9 lpm (0 to 5 gpm)
Internal Leakage: 197 cc/min. (12 cu. in./min.) fully closed at 207 bar (3000 psi)

   (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
Installation: Install D-series coils with two O-rings above and below the coil. Install E-series
   coils with only one O-ring above the coil. Manual override options M and G require Coil Nut Kits.
   See part numbers below. See Cartridge Installation, page 9.020.1 for cartridge, coil and coil
   retainer installation. To assure proper function, coil retainer must be installed.

The EVDR Series controllers are recommended for use with most HydraForce
proportional valves. These newer electronic controllers are versatile, reliable, and
easily configured and customized for a wide range of applications.
See the EVDR Product Selection Guide.
