Proportional throttle valves, proportional flow control valves M22x1,5
Direct operated, pressure compensated proportional flow control valve in screw-in cartridge construction for cavity according to ISO 7789. With the solenoid deenergised, the control spool is held in the closed position (QN) or open position (QO) by a spring. The change of the electric current is followed by a proportional volume flow change. From the input (1), the fluid flows over a throttle and a control spool to the controlled output (2). For the control, Wandfluh proportional amplifiers are available (see register 1.13).
Proportional 2-way flow control cartridge
- direct operated
- Qmax = 25 l/min
- QN max = 25 l/min
- pmax = 350 bar
Proportional flow control valves are suitable for precise speed control, where the load current has to be maintained constant independent of the input and output pressure. The screw-in cartridge is perfectly suitable for installation in control blocks and is installed in sandwich- (vertical stacked systems) and in flange plates (corresponding data sheets in this register). For machining the cartridge cavity in steel and aluminum blocks, cavity tools are available (hire or purchase). Please refer to the data sheets in register 2.13.
