Solenoid Valve Builder
A twelve-character code defines any given valve.
Tabulated information below includes some of these codes.
Consult Exloc for help in building the complete part number.
REMOTE MOUNTING VALVES
3-way (3/2) valve codes
3-way (3/2) valves have a single pressure port for connection to an air cylinder or actuator, an air supply port, and an exhaust port. Both single and dual solenoid designs are available. The pilot operated versions may be built with an internal pilot air passage from the main air supply port (most common), or with an external pilot air connection.

4-way, two-position, (5/2) valve codes
4-way, two-position, (5/2) valves have two pressure ports for connection to double-acting air cylinders and actuators, two exhaust ports, and a common air supply port. Both single and dual solenoid designs are available. Pilot operation is accomplished with an internal air passage from the main air supply port, or alternatively with an external pilot air connection(s).

4-way, three-position, (5/3) valve codes
4-way, three-position, (5/3) valves have two pressure ports for connection to double-acting air cylinders and actuators, two exhaust ports, and a common air supply port. They employ dual solenoids, and have spring return to center with a choice of exhaust port status in the mid-position as shown in the schematics below. Pilot operation is accomplished with an internal air passage from the main air supply port, or alternatively with an external pilot air connection(s).

SUB-BASE MOUNTED SOLENOID VALVES
Most of the remote mounting valves detailed above are available for mounting on a sub-base which becomes the termination point for piping. The valve proper can then be removed from the sub-base without breaking the pipe connections. An air shut off valve is incorporated into the sub-base for this purpose.
For stand-alone valves using this option specify Valve Body Style Code T.
MANIFOLD MOUNTED SOLENOID VALVES
Multiple valves mounted on sub-bases can be bolted together to create a manifold with common air supply and exhaust connections. Pipework is reduced, and space saved. Main air supply and exhaust ports are duplicated at each end of the manifold for convenience, and are sized appropriately. Provision to add valves to expand a system can be made at the outset by including extra sub-bases fitted with blanking plates. Banks of up to ten valves are possible.

Specify Valve Body Style Code V and the number of valves to be ganged together.

Example shows three Model E2318 valves manifold mounted.
NAMUR DIRECT-MOUNT SOLENOID VALVES
These valves conform to the NAMUR standard for direct mounting to air actuators. The flange interface provides for dimensions and location of airways and fixing holes between the solenoid valve and the actuator. The included mating seal plate enables the valve function to be switched between 3-way and 4-way (3/2 and 5/2). Thus, one valve model may be stocked for these alternative functions.
Consult with Exloc for your NAMUR valve requirements.
