WV131S is a normally closed 3/2-way direct acting solenoid valve that stays closed when the coil is de-energized. It is compact and high performing, works from zero minimum differential pressure, responds in 25 to 40 ms and can be energized continuously. It is used in measuring and control equipment, water treatment systems and small compressors.
