2/2-way solenoid valve, pilot-operated, brass, G 3/4, normally closed, FKM seal, 24 V DC - E.MC

Switching large flows with a small coil: the diaphragm pilot-operated G 3/4 valve uses the line pressure to open a 20 mm orifice. It works at a differential of 0.5 to 16 bar. With no current the passage stays shut, so the valve closes the line by itself if the supply fails.

Advantages

• 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.
• Serviceable: diaphragm and coil can be replaced individually while the body stays in the line.

Applications

• Opening and closing G 3/4 water and cooling water circuits.
• 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 24 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.
