when a lot of procurement, our customers are all points not clear of the different types of electric butterfly valve switch controlled by what be respectively?

electric butterfly valve, control by electric butterfly valve switch. Switch type electric butterfly valve is to play the role of switch; External regulation electric butterfly Industrial Valves is to adjust the action of traffic.

1, the original, is also the best check, debugging is gear set counter with a limit switch! The structure of electric door, mainly is two open limit, limit switch, switch (two torque actuation torque too big emergency power in order to protect the valve and motor) , two contactor, of several buttons.

this kind of structure, can open can't close, see first contactor can suck or not? Which limit switch action? Or break up? And close the door interlock of contactor in series with ( Open the door) Button on the normally closed contact, Open the door) Contactor whether the normally closed contact of contact is bad, The common failures often neglected) 吗? To close the door in the direction of the hand shake up, whether the valve is unsmooth phenomenon, eliminate mechanical problems. As long as careful observation, should be able to find out why.

2, intelligent type, such as Italy BIFFI electric door, etc. , are internal microcontroller or DSP control circuit, we also can check, if there is a problem, contact torque Settings are too small, power is changed to causes such as limit value ( Sometimes because of abnormal data, location has now closed more than limit, DSP has shut down) 吗? And so on.

Italy BIFFI electric door I found a mechanical linkage between two contact together ( A frame) Exceptions can cause failure of open can't close. If there is a spare circuit boards, replacement method is used to see if circuit board failure.

electric butterfly valve is suitable for hvac and refrigeration industry, at the same time can also be used in industrial field, general services and water treatment. V4 series electric butterfly valve has a standard & other; On/off & throughout; Type of control and & other; External regulation & throughout; Control ( Control signal for 4 - Ma, or 0 to 20 10伏直流电) Two kinds. Specifications diameter range (- DN600。

electric butterfly valve open or close the valve and the size of input switch signal, the output signal flow size or humidity, if not the output signal, will not be able to adjust the valve works. The principle and principle of electromagnetic valve with the wiring diagram. as a domestic high-end valve manufacturer, always respond to national policy and called for, committed to researching, developing and manufacturing electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valve, the valve to keep traditional valve product sales profits to escort for the innovation research.
