2W Series 2/2-Way Solenoid Valves
Reliable Fluid Control for Air, Water, Oil, Gas and Steam Applications
The 2W Series is designed for general-purpose control of air, water, gas and compatible low-viscosity oils. With brass body , multiple sealing materials and a wide selection of connection sizes, these valves can be integrated into automation equipment, water-treatment systems, heating equipment, filling machinery, compressed-air systems and other industrial installations.
Product Description
The 2W Series is a normally closed, direct-acting solenoid valve developed for controlling air, water, gas and low-viscosity oil. When the coil is energized, the valve opens to allow the medium to flow. When electrical power is removed, the valve returns to its closed position.
The series covers port sizes from 1/8" to 2", making it suitable for both compact equipment and higher-flow industrial pipelines.
