Proportional throttle valve
Description
Direct operated proportional throttle valve in screw-in cartridge construction for cavity according to PU12-3S. With the solenoid deenergised, the control spool is held in the closed position by a spring. The change of the electric current is followed by a proportional volume flow change. Very sensitive opening and closing characteristics and low hysteresis are characteristics of these valves. For the control, Wandfluh proportional amplifiers are available (see register 1.13).
Application
Proportional throttle valves are suitable for smooth control of movements in stationary or mobile systems. The screw-in cartridge is perfectly suitable for installation in control blocks. The third port (relief port) makes this proportional throttle valve ideal for load sensing controls, as we have a clean relief of the LS line in the de-energised position. In combination with our bypass pressure compensator (see data sheet 2.5-675), 3-way proportional flow control functions can be implemented in a highly flexible manner. In combination with our inline pressure compensator (see data sheet 2.5-672), 2-way proportional flow control functions can be implemented.
