Function and application
The QDE3 and QDE5 are compensated proportional flow control valves, with pressure compensation, for subplate mounting. These valves work in 2 or 3 ways, depending on how the interface is made on the mounting surface. They are used for flow control in branches of a hydraulic circuit or for the speed control of hydraulic cylinders. They are available in two sizes, in 5 flow adjustment ranges of up to 80 l/min. They can be controlled directly by a current-controlled power supply, or by an electronic card, to be order separately. Share | Contact us
