5/3-way solenoid valve, pilot-operated, pressure centre, G 1/8, 450 l/min, 230 V AC - E.MC

When an actuator has to stop in a defined way rather than just extend and retract, it needs a third switching position. The pilot-operated valve from the E.MC RV series switches with two 230 V AC 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. Both working ports are then supplied with pressure. With a through rod the forces balance out, with a single rod the area difference pushes the piston slowly outwards.

Advantages

• Valve body and spool in aluminium alloy, HNBR O-rings, pilot unit in engineering plastic.
• 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.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.
• IP65 protection to DIN 40050 and insulation class F, each coil draws 3 VA.

Applications

• Through-rod cylinders that should stay pressurised and force-balanced in the centre position.
• Compact handling assemblies with short tubing runs and small cylinders on G 1/8 ports.
• Simple controls that run directly on 230 V AC without a power supply.

Accessories and spare parts

A matching 230 V AC 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.
