Wuxi east technology co. , LTD. Is a collection of the control valve industry manufacturing, development, production, assembly, sales and service in the integration of science and technology enterprises, professional research and development of electric valve, pneumatic valves, hydraulic valves, pneumatic actuators and various kinds of complete sets of pneumatic valve. Our company produce all kinds of pneumatic ball valves, butterfly valves, plug valves, regulating valve, gate valve, globe valve, flat gate valve and pneumatic device or valve products. During normal use of electric valve if there is a back and forth how to solve? Electric valve with stainless steel flange type electric ball valves, electric rail rectangular shutter type adjustment ball valves, electric butterfly valve, Z973H/X/F electric wafer blade through cut-off valve, gate valve, J941 electric flange link CV3000 - DHCB electric cage control valve adjustment and DVJR electric type O cut off ( Adjust) Ball valve, ZDLM explosion-proof electric socket regulating valve, etc. , there are many different kinds of models. In solving the fault before you first try to increase the dead zone can see troubleshooting, if problems ruled out, then dead zone is set too small; If still not solve the problem, check the steering actuator feedback signal is the same. Problem solving is that electric valve return difference set is too large; If failed to solve, then check whether the input signal is stable. Checked out the problem of the input signal is still not solved, the inspection schedule is set too small, can be appropriately increased. Finally, check whether the circuit board failure.
