Description

3" Normally Closed Brass Solenoid Valve – 8621-ESM-NBR (PU225A-28)


High-flow 3" brass normally closed solenoid valve for air, water, oils, LPG, diesel, petrol, propane, inert gases and other compatible fluids. Designed for reliable operation in demanding industrial applications, the valve remains closed without power and opens only when energised.

With an extra-large 80 mm orifice and Kv flow factor of 1380 L/min, the 8621-ESM-NBR is ideal for high-flow water systems, fuel transfer applications, gas distribution systems, cooling circuits and process control installations requiring normally closed operation.
