Function

WH and WP valves are fluidically operated directional spool valves. They are used for the control of stop, start and direction of a flow.

The directional valves mainly consist of housing (1), the control spool (2), one or two return springs (3), cover (4). In the non-operated condition, control spool (3) is held by return springs (4) in the central or initial position (except for impulse spools).

Control spool (3) is shifted by the actuating elements to the required spool position.

Without return spring, without detent, type..O/...

(Only for Spool Symbol A,C,D)

When actuating elements without return springs and without detent are used, a defined spool position is not provided in the on-operated condition.

With detent, type..OF/..

(Only for Spool Symbol A,C,D)

Directional valves with hydraulic or pneumatic actuation are also available as 2-position valves with detent. When actuating elements with detent are used, each spool position can be fixed.

Cartridge throttle

The use of a throttle insert is required when, due to the prevailing operating conditions, flows can occur during the switching process that are higher than permitted by the performance limits of the valve. It is to be inserted in the P-channel of the directional valve.
