Technical Specifications​

Valve family: 24 Series, 4-way spool.

Maximum Cv: 0.4.

Port sizes: #10-32, M5, or M7 depending on ordered body.

Configuration: inline or manifold, plug-in/non-plug-in.

Pilot: 8 mm E-pilot with oval armature, solenoid operated.

Media: compressed air, inert gas, vacuum with external pilot option.

Internal pilot pressure: approximately 2.3 bar to 8 bar for spring-return single solenoid; 1.3 bar to 8 bar for double solenoid air-reset configurations.

Filtration: 40 µm minimum, non-lubricated operation acceptable.

Electrical: configurable coil voltage; common 24 VDC, 12 VDC, 110 VAC, 220 VAC per ordering code.

Temperature: -10°C to 60°C standard.

Functional Features​

Balanced pilot design for repeatable shift force.

Response time independent of inlet-pressure fluctuation.

High flow for 10 mm valve body.

Plug-in or standalone manifold mounting.

UL, CSA, CE, RoHS compliance on qualified variants.

Material Composition and Structure​

Anodized aluminum/spool body, stainless and engineered polymer seals, copper-coil solenoid with epoxy encapsulation, plug-in or non-plug-in manifold interface. Compact 10 mm footprint with 8 mm pilot cartridge.

Working Principle​

The solenoid pilot pressurizes one end of the main spool. The balanced spool shifts to route supply and exhaust ports in a 4-way path. De-energizing or energizing the opposite coil shifts the spool to the alternate position; spring or air return defines fail-state behavior.

Installation Requirements​

Mount on clean compressed-air supply filtered to 40 µm. Choose inline or manifold base matching port thread. Torque fittings to MAC specification. Provide correct coil voltage and polarity for DC coils. Allow ventilation space for solenoid heat dissipation.

Usage Notes​

Verify Cv and port size against actuator flow demand. Do not operate above rated pressure for the selected pilot option. Use external pilot for vacuum or very low supply pressure. Inspect seals and spool periodically in high-cycle applications.
