Hydraulic Directional Control Valves are used to control the hydraulic oil flow path to an actuator (cylinder or motor).  The variety of spool options available allow for various movement types based on the application requirements of your cylinder or motor.  Proven high quality robust valve design successfully designed into many high volume applications.

• D03 (NG6) Cetop mounting.  Can be mounted to standard available subplates and bar manifolds.
• Maximum flow of 21 gpm for DC power and 15.8 gpm for AC (reference Solenoid Power limit chart)
• Maximum working pressure = 4560psi (315 Bar)
• 3-position, 4-way, Spring centered, energize to shift
• Double solenoid operated
• Removable Coil
• Valve can be mounted in any direction
• Coil can be rotated to optimal connector position
• Uses DIN 46350 Form A electrical connection type
• Includes lighted DIN connector for each coil.  LED illuminate’s clear connector housing when power is supplied to the connector/coil.  IP65 rating
• NBR Buna Seals
• Four fastening screws included, M5x45mm long
• White label with no logo for OEM manufacturers.
• Weight = 4.3 lbs (1.95 kg)
• Solenoid Power: DC=30watts, AC=50VA holding and 220VA inrush

Upgrade from the following manufactures:

Note: These are the basic model codes.  Confirm the spool type symbol, voltage and electrical connector style.

Options:

Solenoid Voltage: 12VDC, 24VDC, 110VAC (50 or 60 hz), 220VAC (50 or 60 hz)

Soft Shift:  3-5 times slower solenoid shift time, 75-225ms (DC coils) versus 25-45ms for a standard DC valve.

Spool Configurations:

C:  Closed center spool, all ports blocked when centered.

Useful to switch actuator directions and to fully stop cylinder or motor when centered.  Make sure there is a relief valve to protect overrunning loads from spiking the pressure during sudden stops when centering.  Note that there is some leakage of oil across the spool in the center position and slow drifting of the actuator could be possible.

M:  Motor spool, A and B ports to tank and P port blocked when centered. 

Actuators will move freely from external forces when the valve is in the center position.  Motors and cylinders will coast to a stop when centering.  Adding an A&B port P.O. check valve under this valve will ensure a positive stop and hold the position of a motor and cylinder for longer durations than with just a closed center spool valve C.

T:  Tandem Spool, A and B ports closed and P to T in center position:

Actuators will stop in center position and the supply pressure will be directed to tank.  Commonly used with fixed displacement gear pumps so pressure can flow direct to tank and not build up heat by blowing across a relieve valve as would be needed with the M and C spool.

H: Open Center Spool, A, B P and T ports connected in center.

Actuators will freely move when valve is de-energized and spring centered.  Pressure and all ports will drain to tank.  Energize solenoid “a” and “b” to change direction of actuator.
