2/2-way solenoid valve, pilot-operated, brass, G 3/4, normally closed, FKM seal, 12 V DC - E.MC

On G 3/4 supply and feed lines carrying compressed air, water or oil, this valve opens a 20 mm orifice. A diaphragm does the heavy work while the coil only controls the pilot channel, which keeps consumption at 10 W. With no current the passage stays shut, so the valve closes the line by itself if the supply fails.

Advantages

• Serviceable: diaphragm and coil can be replaced individually while the body stays in the line.
• Large orifice, small coil: 20 mm orifice at just 10 W, thanks to diaphragm pilot operation.
• Flow: Cv 9.5 according to the E.MC datasheet, Kv 108 l/min.
• FKM (Viton) seal: An alternative to NBR, for example for light oil up to 20 cSt.
• Brass body and IP65: class F coil insulation, watertight connector to DIN 40050.

Applications

• Shutting off G 3/4 compressed air feed lines upstream of machines or service units.
• Systems where the line must close by itself if power fails.
• Lines carrying light oil up to 20 cSt where a Viton seal is preferred.
• Note: in service the valve needs at least 0.5 bar differential and flow at the outlet. If the pressure equalises, it no longer switches reliably.

Accessories and spare parts

• Replacement coil type Y for 12 V DC, exchangeable without opening the line.
• Replacement diaphragms for G 3/4 in NBR, FKM and EPDM, sold individually, also for changing the seal material.

The valve belongs to the E.MC ELP series and is supplied with coil and connector.
