Solenoid Directional Control Valve is Made of Durable Materials

Solenoid directional control valve is used in the hydraulics industry. These types of valves use electromechanical solenoids for sliding of the spool. These valves are used extensively because they can be simply controlled by electric power. To generate large forces the valve needs large amounts of electrical power.  The valves heat up over a period of time and hence pose a threat to extended use. The duty cycles can be limited to prevent heat generation. Their direct acting can only be used for low actuating forces.

Low power solenoid valves operate small pilots that start the flow of liquid that drives a larger hydraulic valve that uses more power. The 3 ported 2 position valve is a pilot valve also called bi-stable pneumatic valve. It can retain its position during loss of power.

Directional control valves can be classified according to number of ports, number of positions, actuating methods and type of spool. The number of entries and exits through which fluid flows in and out of the valve establishes it as a two way or a three way or a four way valve.

Number of positions refers to the normal and working positions which a valve spool can take. You can have a two position, three position and proportional valves. There are four basic actuating methods for these valves: manual, mechanical, hydraulic and solenoid. Simple levers and paddles are used in manual valves. Springs are used to recover the valve position.  A lever or external pneumatic or hydraulic signal is used to return the spool. In mechanical valves, cams, wheels, rollers are used to apply force. These are not as durable and have a limited life. Hydraulic valves are used for higher pressures. They are made of durable materials.

Solenoid Directional Control Valve for Single and Double Acting Cylinders

Solenoid directional control valve actuates single or double acting cylinders. The valves can be used with most hydraulic pumps.  The poppet-style pumps are designed for zero-leakage and maintain the desired pressure without generating heat.

The 3 and 4 way directional control valves can be mounted to international standard valve sub-plate D03, NG6, and ISO 03.  The D03 valves are available in four styles:

·         2 Position, 4 way 

·         3 Position, 4 way

·         2 Position, 3 way

·         2 Position, double 3-way

They are best for applications that require pressure up to 500 psi (340 bar). They integrate well with IDI air-driven liquid pumps. The valves feature O ring seals and backup rings made of polyurethane PTFE.  You can also ask for Viton or EPR instead of polyurethane. Hardened and ground steel has been used in making the poppets and seats. The body is made of aluminum which is non-ferrous metal, thus making it very durable.  The valve is resistant to cold and heat. It is ideal for temperatures ranging from -65° to 225°F.

The device can be ordered for use with four voltage, 12VDC, 24VDC, 115VAC and 230VAC. The light weight valve is an ideal choice for those who want the best quality at a low price. You can order the valve with or without solenoids, connectors and bolt kits. You can also get a pressure port check valve with the order. The construction of the directional poppet style control valves allow for mounting multiple valves on standard 2.0-inch (50.8 mm) centers.
