Directly Operated Proportional Directional Valve
In connection with this valve, the points applicable to the following proportional directional valves will also be discussed by way of example such as hysteresis, repetition accuracy, control spool, basic principles tor characteristic curves and the time characteristics of the … Continue reading
Stroke-Controlled Proportional Solenoid
In the case ol the stroke-controlled solenoid (Fig 10). the position of the armature is controlled by a ciosed-loop control circuit and maintained irrespective of the counter-pressure. provided it is within the rated working range of the solenoid. With the … Continue reading
Force-controlled Proportional Solenoid
The solenoid force is controlled by the change in current I in the lorce-controlled solenoid without the armature of the solenoid performing a measurable stroke. Due to current feedback in the electrical amplifier, the solenoid current and therefore the solenoid … Continue reading
2-Way Proportional Throttle Valve
This combination unit, can be used as a throttle (orifice) or in conjunction with a pressure compensator for controlling high flows The applications include, for example. control systems for presses and plastic processing machines Despite the high flow rates, the … Continue reading
2-Way Proportional Flow Control Valve with Downstream Pressure Compensator
The 2-way proportional flow control valve can control, independent o’ pressure and temperature, oil flow specified by the electrical signal. The most important components are the housing (t). the proportional solenoid with inductive positional transducer (2), the measuring orifice (3). … Continue reading
Directly Operated Proportional Pressure Relief Valve
The proportional pressure relief valve is designed as a poppet valve It basically consists of the housing (1), proportional solenoid (2) with inductive positional transducer (3), valve seat (4), valve poppet (5) as well as compression spring (6) The proportional … Continue reading
Pilot Controlled Proportional Pressure Relief Valve
Pilot controlled valves are used for applications involving higher How rates. The valve consists of the pilot valve (1) with proportional solenoid (2), optionally with integrated max. pressure safety control (3) and main valve (4) with main spool (5). The … Continue reading
Hydraulic Proportional Solenoids
Proportional solenoids represent the linking element between electronic and hydraulic. The proportional solenoids are a form of DC linear solenoids. Proportional to the electrical current as the input variable, the produce force and travel as the output variable. Corresponding to … Continue reading
