HAWE Directional Seated Valve WH 1 H G24

The directional seated valves type WN and WH are are manifold mounting valves of compact design and feature 2/2-, 3/2-way functions. 2/2-, 3/2-way functions are possible by combining two individual valves on one joint sub-plate. These are also available combined as 3/3 and 4/3 directional seated valves.

The type WH contains an internal pressure balance. As a result, the permissible operating pressure is higher than the type WN.

Appropriate connection blocks enable direct pipe connection. The directional seated valves are available in a combination of valves in valve bank type BWN and BWH.

• All functionally important components, from the solenoid armature to the valve elements, are lubricated by the hydraulic fluid, therefore no maintenance is required.
• Type WN is only available as size 1. The armature cavity is pressure resistant up to 300 bar and directly connected to port R. This means that between the solenoid armature and the valve elements only a simple pin (with no seal) is required. This results in a very long service life (no seal wear). The solenoid force is largely dependent on the respective pressures to be switched. This often enables operation with reduced supply voltage thereby reducing the solenoid temperature and increasing its service life.
