The 3WH 6 A5X/O/B10 is a directional spool valve from the German company Bosch Rexorth. Spool valves use a cylindrical spool valve body with a port that connects to a piston inside a cylinder. The spool valve controls the flow of fluid or gas through the port based on the position of the piston. These types of valves offer high precision and repeatability, and are often used in applications where accurate control over speed and direction is required. They are commonly found in mobile equipment like construction vehicles and agricultural machinery, but they are also suitable for stationary uses such as in processing plants and factories. The specific valve you mentioned appears to be a hydraulic valve designed for use in pneumatic or hydraulic systems. It has a maximum operating pressure of 210 bar and a nominal flow quantity of up to 40 lpm. Additional details about this particular valve may be available from the manufacturer's website or product catalogue. As always, it's important to carefully consider the specifications and requirements of any application before selecting a valve.
General information
Valves of type WH are fluidically actuated directional spool valves. They control the start, stop and direction of a flow.
The directional valves basically consist of housing (1), one or two actuation elements (2) (hydraulic actuation cylinder), control spool (3) and one or two return springs (4). The ports for the control are positioned radially (5).
When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except impulse spool).
The control spool (3) is moved to the desired spool position by means of the actuation elements.
Throttle insert
The use of a throttle insert is required when due to prevailing operating conditions, flows can occur during the switching processes, which exceed the performance limit of the valve.
It is inserted in channel P of the directional valve.
Typ 4WH 6 E5X/…
Without spring return, with detent,
version ..OF/..
Directional valves with hydraulic actuation are also available as a 2-spool position valve with detent (7). If actuation elements with detent are used, each spool position can be locked.
Without spring return,
version ..O/..
If actuation elements without return springs and without detent are used, there is no defined spool position in the de-energized state.
