5/3-way solenoid valve, pilot-operated, pressure centre, G 1/2, 1350 l/min, 230 V AC - E.MC

A 5/3-way valve drives a double-acting cylinder in both directions and decides what happens in the third position. The pilot-operated valve from the E.MC RV series switches with two 230 V AC coils and passes up to 1350 l/min at its G 1/2 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

• Operating pressure of 1.5 to 8 bar with a 12 bar test pressure, and the air does not need to be lubricated.
• Flow rate of 1350 l/min at 6.2 mm nominal diameter and 30 mm² effective area (Cv 1.67), enough air for brisk strokes without the valve throttling them.
• IP65 protection to DIN 40050 and insulation class F, each coil draws 4 VA.
• Response time below 0.05 s and up to 3 cycles per second for cycled sequences.

Applications

• Gentle follow-up stroke of a single-rod cylinder driven by the area difference.
• Large-volume cylinders and rotary actuators that need 1350 l/min at a G 1/2 port.
• 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 T1, is available separately. For wiring with plug-in connectors, E.MC lists connection cables in 0.3, 0.6 and 1 m lengths.
