PD42-M45 Valve

PD42-M45 Valve symbol

A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for
two-way circuits requiring remote pilot actuation.

In neutral (unpiloted), the PD42-M45 allows flow from 2 to 3 bidirectionally. On remote pilot
signal at 1, the valve shifts to block 2 to 3 bidirectionally. The spring chamber is vented to port 4
which is internally o-ring sealed from the cartridge flow paths. Pressure on port 4 will directly (1:1)
affect required pilot pressure and must always be added to the bias spring value..

• Rated for 345 bar (5000 psi) operating pressure (polyurethane seals required).
• Hardened spool and cage for long life.
• Optional sealed pilot
• Industry-common ISO cavity.

Operating Pressure: 345 bar (5000 psi)
Proof Pressure: 690 bar (10000 psi)
Burst Pressure: 1034 bar (15,000 psi)
Flow: up to 265 lpm (70 gpm)
Internal Leakage: 245 cc/minute (15 cu. in./minute) at 345 bar (5000 psi);
   zero leakage from port 1 to 2 with sealed spool.
Temperature: -40 to 100C (-40 to 212F) with Buna seals;
   -26 to 204C (-15 to 400F) with Fluorocarbon seals;
   -54 to 107C (-65F to 225F) with Polyurethane seals
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of
   7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
