Product Overview
The HAWE NZP 16 Q 22 directional seat valve (part number 2535529) is a precision-engineered, leak-free poppet-type directional control valve manufactured by HAWE Hydraulik. Unlike conventional spool valves, the NZP series utilizes a seated (ball/cone) design that guarantees zero internal leakage in the closed position, making it ideal for load-holding and pressure-holding circuits. The “16” designates the nominal size (NG 16) with a maximum operating pressure of up to 400 bar, while the “Q 22” code specifies the specific spool/actuation configuration and flow characteristics. This valve is designed for direct, space-saving manifold mounting and is actuated via a solenoid or mechanically, depending on the configured variant. It serves as a critical control element in high-pressure industrial hydraulic systems where absolute sealing integrity and rapid, reliable switching are mandatory.
