Directional Seat Valve Pneumatic series W2N

Pressure [bar]


Flow rate [L/min]


The W2N… / W2P… series of 2/2 … 4/4 pneumatic operation directional seat valves are direct acting, pressure balanced, manifold-mounting valves with a size 03 interface to ISO 4401-03-02. 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 W1…). Dependent on the operating position, the ports are either closed with virtually zero leakage, or open and flow is possible in either direction. The “overlapped” model (W2P…) features a closed crossover characteristic i.e. during the valve’s switching period, there is no connection between the ports and therefore only a minimal loss of flow/pressure occurs. 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. These hand operated seat valves are predominantly used in certain mobile and industrial applications where leak-tight shut-off functions are crucially important.
