2/2-way solenoid valve, pilot-operated, brass, G 1/2, normally closed, EPDM seal, 230 V AC - E.MC

Switching large flows with a small coil: the diaphragm pilot-operated G 1/2 valve uses the line pressure to open a 15 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

• Flow: Cv 5.5 according to the E.MC datasheet, Kv 64 l/min.
• EPDM seal: The right choice for air and hot water.
• 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: 15 mm orifice at just 15 VA, thanks to diaphragm pilot operation.

Applications

• Opening and closing G 1/2 water and cooling water circuits.
• Systems where the line must close by itself if power fails.
• Hot water and rinsing circuits where EPDM is the intended seal material.
• 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 230 V AC, exchangeable without opening the line.
• Replacement diaphragms for G 3/8 and G 1/2 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.
