DESCRIPTION
A solenoid valve operated, 2-way 2-positions, normally closed, piloted poppet type, screw-in cartridge valve. Typically used as a
blocking or load holding device for high pressure circuits. When the coil is de-energized, the SVT0.S12 acts as check valve allowing
free flow from 1 to 2, while blocking from 2 to 1. When the coil is energized the poppet lifts and opens both the 2 to 1 and 1 to 2 flow
paths. The rigid design using a 1-piece body contributes to minimize the effect of eccentricities in cavity and provides great
reliability. Low pressure drop thanks to optimized flow path.
