Throttle valves with pressure compensators are
used to ensure a constant flow rate and thereby a
constant speed of the actuator independently of
the load induced pressure changes .
The valve consists of a body (1) with thread 7/8-
14-UNF, bush (2) pressure compensator spool (3),
adjusting screw (4) with locking nut and spring.
The working fluid enters the valve from its nose side
(1), goes through the throttle orifice in the spool and
flows out through the radial holes (3) to the consu-
mer. The spool of the compensator keeps constant
pressure gradient by draining off a part of fluid
through the radial holes (2). Thereby the constant
flow through the valve is assured. The flow rate
can be preset by adjusting the screw with lock nut.
When the flowing in a reverse direction, the pressu-
re compensator is functionless.
The valve body, adjustment screw and lock nut are
zinc coated.
