DMDAZ

3-way, solenoid-operated directional spool valve with position switch

SERIES 1 / CAPACITY: 45 L/min. / CAVITY: T-11A

Z-Control, B-Spool

Z-Control, R-Spool

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition

between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of

particular importance in pilot control circuits.

The position switch provides confirmation that the valve is in the spring biased position.

A coil must be ordered with this cartridge. This cartridge is supplied as a sealed, factory set unit and is not field serviceable. If the assembly requires changes or

service it needs to be returned to the factory. Any tampering will violate the product warranty.

Position switch is CE approved.

When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.

The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.

This valve is direct actuated and requires no minimum hydraulic pressure for operation.

This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a

factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes

that will affect the function of the cartridge.

A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.

The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.

Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge

machining variations.
