2/2-way solenoid valve, pilot-operated, brass, G 1, normally closed, NBR seal, 24 V AC - E.MC

Switching large flows with a small coil: the diaphragm pilot-operated G 1 valve uses the line pressure to open a 25 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

• NBR seal: Standard seal for compressed air, water and 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.
• Large orifice, small coil: 25 mm orifice at just 15 VA, thanks to diaphragm pilot operation.
• Flow: Cv 12.5 according to the E.MC datasheet, Kv 171 l/min.

Applications

• Shutting off G 1 compressed air feed lines upstream of machines or service units.
• Systems where the line must close by itself if power fails.
• General compressed air and water duty up to 80 °C media temperature.
• 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 AC, exchangeable without opening the line.
• Replacement diaphragms for G 1 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.
