The application of proportional multiple directional control pneumatic valve

proportional multiple directional control pneumatic valve has been working with high efficiency, low cost and was deeply loved by mobile hydraulic machinery manufacturers. Electro-hydraulic proportional pneumatic valve according to the proportion of electronic rocker signal corresponding change the pilot pressure proportional pneumatic valve, so as to change the position of the pneumatic valve. Electro-hydraulic proportional pneumatic valve, pneumatic valve is proportional flow rate reduced pressure pneumatic valve, reversing pneumatic valve. For the sake of manufacturing cost, and is generally not configuration mechanical/inductive position sensor, and the corresponding electronic detection and error correction function. So, choose electrohydraulic proportional directional control pneumatic valve must pay attention to: in the process of operation, to fully rely on operator's visual observation to ensure the safety of the operation. In the electronic control, remote control operation, should pay attention to guard against the phenomenon of outside interference.

proportion servo multiple directional control pneumatic valve control of high precision, good protection. Recently, due to the development of electronic technology makes the manufacture cost, a big drop in electro-hydraulic proportional servo pneumatic valve is more and more get the welcome of mobile hydraulic machinery manufacturers. Electro-hydraulic proportional servo pneumatic valve, pneumatic valve by proportional electromagnetic position feedback, servo drive and electronic modules, closed-loop position feedback control. With inductive position sensor LDVT electronic module configuration, and the corresponding electronic detection and error correction function.

electro-hydraulic proportional servo pneumatic valve is based on the electronic rocker rate signal corresponding to change the position of the servo drive, so as to change the position of the pneumatic valve. When the rocker signal and slide the position of the pneumatic valve stroke out of proportion, the electronic module signal error correction, drive to drive the reversing pneumatic valve pneumatic valve automatically back to zero, the hydraulic automatic stop. Multi-channel pneumatic valve pneumatic valve core and servo driver for mechanical

universal shaft connection, the piston connecting rod thrust is greater than the kilograms, so in the process of operation, which can avoid the pneumatic valve heart stuck, and can effectively guard against accidental operation. Manual operation, servo driving mechanism of the pressure release completely in a floating state, manually pull rod can operate freely.

proportion servo driver is big traffic mechanical/manual multi-channel pneumatic valve electro-hydraulic driven form a complete set of high technology, low cost retrofit scheme selection. Rate servo driver by pneumatic valve, electromagnetic relief servo cylinder and electronic module ( With inductive position sensor LDVT, position detection and error correction function) , flange connection and connecting rod connecting the two ways, with manufacturers in domestic and foreign mechanical reversing pneumatic valve matching, is one of the multiple directional control pneumatic valve electro-hydraulic transforming the best choice.
