日本油研單向調速閥應用指南，YUKEN調速閥

概述：
by the variation in the pressure (load) and temperature
(viscosity of hydraulic fluids).  These valves are optimal
and speed change of the actuator are required to be d one without shocks.
for such a usage where the start-up, stop
These valves vary their output flow proportionally to an input current,
The valves are used together with the applicable power amplifiers
and optionally regulated. Furthermore, as the valves have the functions of pressure
and temperature compensation, the flow rate is not affected
therefore, by controlling the input current f rom the power amplifier,
the flow rate in the system can be continuously, remotely
