5/3-way solenoid valve, pilot-operated, closed centre, G 1/8, 450 l/min, 24 V DC - E.MC

Double-acting cylinders and rotary actuators need two working ports and, depending on the job, a clearly defined rest position. The pilot-operated valve from the E.MC RV series switches with two 24 V DC coils and passes up to 450 l/min at its G 1/8 port. With neither coil energised, the spool sits in the centre position. All ports are then blocked, so the cylinder stops where the signal drops out, with air trapped in both chambers.

Advantages

• Flow rate of 450 l/min at 3.4 mm nominal diameter and 9 mm² effective area (Cv 0.50), enough air for brisk strokes without the valve throttling them.
• IP65 protection to DIN 40050 and insulation class F, each coil draws 2.8 W.
• Operating pressure of 1.5 to 8 bar with a 12 bar test pressure, and the air does not need to be lubricated.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.

Applications

• Holding the piston position when both control signals drop out at the same time.
• Compact handling assemblies with short tubing runs and small cylinders on G 1/8 ports.
• Direct control from PLC outputs at 24 V DC.

Accessories and spare parts

A matching 24 V DC replacement coil, type S, is available separately. For wiring with plug-in connectors, E.MC lists connection cables in 0.3, 0.6 and 1 m lengths.
