The EEX-W2N… series of 2/2 … 4/3 solenoid operated directional seat valves are direct acting, pressure balanced, manifold-mounting valves with a size 03 interface to ISO 4401-03-02. An EX-protected solenoid for explosive gas atmospheres (II 2 G) is used to provide electrical operation of the cartridge. The main components of the valves are a manifold-mounting body and the push-in 2/2 or 3/2 directional seat valve cartridge (type EEX-W1.B…). Dependent on the operating position, the ports are either closed with virtually zero leakage, or open and flow is possible in either direction. These solenoid operated seat valves are also available with or without manual override lever. For applications where a check valve or an orifice in the P port is necessary, either of these features can be included as an option. They are suitable where leak-tight shut-off functions are crucially important. Examples are where loads, tensions, or clamping forces must be held without leakage. All external parts of the valve are corrosion-protected, and the valves are thus also suitable for use outdoors.
