When energized,,the valve acts as a check valve,allowing flow from T to P ,while blocking flow from P to T.
When de-energizedallowing flow from P to T,and flow from T to P.
To override,push button and remain,the valve blocking from P to T;Release the button,then the valve allowing flow from P to T and T to P.
*Can be replace with Hydraforce SV12-23,SV16-23
DHF08-224
When de-energized,the valve blocks flow in both directions,
When energized,allowing flow from P to T and T to P.
To override,push button in,twist counter-clockwise 90 degree and release,the valve will remain open;push button in,twist clockwise 90 degree and release, the valve will remain close.
DHF08-225
When energized,the valve blocks flow in both directions,
When de-energized,allowing flow from P to T and T to P.
To override,push button in,twist counter-clockwise 90 degree and release,the valve will remain open;push button in,twist clockwise 90 degree and release, the valve will remain close.

[ Hydraulic cartridge solenoid valve]
A Hydraulic cartridge solenoid valve is an electromechanical valve for use with liquid controlled by running or stopping an electrical current through a solenoid, which is a coil of wire, thus changing the state of the Cartridge Solenoid Valve.
A cartridge solenoid valve has two main parts: the solenoid and the cartridge valve. The solenoid converts electrical energy into mechanical energy which, in turn, opens or closes the cartridge valve mechanically.
The operation of a cartridge solenoid valve is similar to that of a light switch, but typically controls the flow of liquid. Solenoid valves may have two or more ports: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple cartridge solenoid valves can be placed together on a manifold block.

Hydraulic Cartridge Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, distribute or mix fluids. They are found in many hydraulic application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.

[ Features of cartridge valves]

1.Light weight and compact size
-Combining several functions into a single manifold may save valuable space and weight, often occupying only 10% to 20% as much volume as conventional line-mounted systems plumbed with fittings, hose, and tubing.

2.Leakage prevention
-Because a valve package eliminates so many connections, system leakage potential is reduced drastically.

3.Efficiency for the system
-Valve packages that eliminate interconnecting lines and fittings lead to higher overall system efficiencies

4. Convenience and Serviceability
-Being more compact, valve packages sometimes can be mounted where they are less susceptible to external damage.
-Cartridges usually can be removed and replaced quickly without disturbing any external plumbing.

5. Aesthetics and Economy
-A clean design will not affect performance, but a good-looking machine on the dealer's sales floor in a competitive market can be an advantage to the OEM.
-On many systems, the cost of a custom valve package ,can be equal to (or less than) that of a system with individually plumbed components.
