A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic
directional valve for three-way circuits requiring remote pilot actuation.
In neutral (unpiloted), the PD10-40 allows flow from 3 to 2 bidirectionally
while flow is blocked at 4. ‘V’ is a spring chamber vent-to-atmosphere, which
is internally O-ring sealed from the cartridge flow paths. On remote pilot signal
at 1, the valve shifts to allow flow between 3 and 4 while blocking at 2.
Because of the vented spring chamber, the cartridge may be fully pressurized at
any port without affecting required pilot pressure.
• Hardened spool and cage for long life.
• Industry common cavity.
Operating Pressure: 240 bar (3500 psi)
Proof Pressure: 350 bar (5075 psi)
Flow: up to 38 lpm (10 gpm)
Maximum Internal Leakage at 207 bar (3000 psi): 82 cc/minute (5 cu. in./minute)
Pilot Pressure Required:
To Spool Crossover: 7.6 bar (110 psi)
To Full Spool Shift: 8.6 bar (125 psi)
Oil Volume Required to Full Shift: 0.65 cc (0.04 cu. in.)
Temperature: -40 to 100°C (-40 to 212°F) with Buna seals;
-26 to 204°C (-15 to 400°F) with fluorocarbon 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
Installation: No restrictions; See page 9.020.1
Cavity: VC10-4; See page 9.110.1_4w
Cavity Tool: CT10-4xx; See page 8.600.1
Seal Kit: SK10-4x-MMM; See page 8.650.1
Cap Vent Seal: 6003117
Note: This valve is designed with a dynamic oil-to-atmosphere seal in the vent
section. Ambient conditions will cause this vent seal to degrade which will reduce
the valve’s cycle life. If this could cause a problem, we suggest that a non-vented
model be selected, or special seal be used. Consult factory for assistance.
Cartridge: Weight: 0.16 kg (0.35 lb);
Steel with hardened work surfaces.
Zinc-plated exposed surfaces; Buna N
O-rings and polyester elastomer back-ups standard.
Standard Ported Body:
Weight: 0.34 kg (0.75 lb); Anodized high-strength 6061 T6 aluminum alloy, rated to
207 bar (3000 psi). Ductile iron bodies available; dimensions may differ.
