Type ADH.5 distributors are intended for interrupting, inserting and diverting a hydraulic
system flow. Normally these distributors are composed of a main stage, crossed by circuit
main flow, and of a pilot stage available in several versions.
Various types of controls are available, used either individually or in combination for, among
other functions, stroke limitation and main spool movement speed control, in order to optimize
the hydraulic system operation where this type of valve is employed.
In those case where normally to drain spools are used, it is necessary to remember that the
minimum changeover pressure due to the opposing springs is equal to approximately 7 bar
(see the operating features table on page I•45) and consequently necessary to insert a check
valve in the P way (as shown above).
• Mounting surface in accordance with UNI ISO 4401 - 05 - 05 - 0 - 94 standard (ex CETOP
R 35 H 4.2-4-05).
Pilot operated spool, solenoid controller.
• Stroke control of main spool.
Presetting for pressure reducing valve mounting.
Presetting for single-acting throttle valve mounting.
