1 VALVE POSITIONER1 GENERALALHVP-20 Series Smart VALVE POSITIONER Controls VALVE stroke accurately in line of input signal of 4~20mA which inputed from controller. Highly efficient microprocessor built in ALHVP-20 performs various and powerful functions like Auto-calibration, PID control, alarm and HART principle is different from the traditional electro pneumatic VALVE POSITIONER . ALHVP smart VALVE POSITIONER and pneumatic actuator make up of a feedback controlling loop, where the position feedback signal of control VALVE is regarded as controlled variable compared with the fixed signal value in the microprocessor.

2 The warp of these two signals emits the pulse of different length by the output of the main control board that Controls I/P conversion unit pressure output, and drives the control VALVE to act( ). pneumatic control VALVE withsmart VALVE POSITIONER can conquer the friction and the imbalance force of the plug and improve the response speed, make the location more rapid, accurate and is especiallly suitable for the situation of librating continually. Through the upper location computer, the users can read and write the basic device management information about working location number, device number, product serial meanwhile monitor the dynamic information of the control VALVE (as the whole opening, ).

3 It can adjust and set the control parameter by using the button, hand-holding setting or the upper location computer at any moment. Resolve the trouble of changing the VALVE for the change of control system, only does user reset and readjust the parameter of the smart VALVE POSITIONER . Therefore, it is widely used in the automatic control system of the petroleum, chemical industry, electric power, metallurgy, light ALHVP-20 series 2 SPECIFICATIONM odelALHVP2009 ALHVP2011 Input signal4~20mA(2 wire)Input load voltage12 VDCS upply ~ ~ MPaSupply power24 VDCI mpedance550ohmStroke Linear:10~100mm Rotary.
