Description
Pilot-operated 3/2-way solenoid valve with servo piston, pressure connection closed without current, sleeve connection. For controlling high pressures at large nominal diameters with low power consumption, minimum pressure difference required 0.5 bar, oil-free operation possible. For neutral gases and liquids such as compressed air, water, hydraulic fluids based on water and mineral oil. A robust valve for controlling larger cylinders and actuators.
