Electric Three-way Confluence and Shunt-off Regulating Valve

• 

Electric three-way confluence and shunt control valves are guided by cylindrical thin-walled window-…

A brief introduction:
ZAZQ, ZAZX seriesElectric three confluence, shunt valveThe cylinder shaped valve type thin window guide.With DKZ straight travel electric actuator, take 0 ~ 10 or 4 ~ 20mA.DC signal to drive the valve opening and closing.The three confluence valve for two kinds of fluid mixed into a three fluid, or different temperature of the same fluid, mixed into the same temperature fluid.Three shunt valve will be a fluid into two fluid.
ZAZQ, ZAZX seriesElectric three confluence, shunt valveThe caliber of the product from 25mm to 200mm, nominal pressure 1, 1.6, 4, 6.4MPa, temperature range of -60 to 450 DEG C, the control signal is 0~10 or 4 ~ 20mA.DC.With different actuators can be divided into common type and the electronic type two.
Two, work principle:
ZAZQ, ZAZX seriesElectric three confluence, shunt valveComposed of DKZ electric actuator and three confluence or three shunt valve, with power supply as power, accept the standard signal, 0 ~ 10mA or 4 ~ DC 20mA DC drives the valve opening and the corresponding operation signal.The confluence of valve is the role of the two kinds of the three kinds of fluid exchange synthetic fluid, a fluid diverter valve is divided into two fluid.Shunt valve can only be selected corresponding confluence, but when DN = 80, the mixing valve can be used for streaming applications.Can replace two single seat control valve, saving investment, small occupied space.Three valve commonly used in two kinds of medium heat exchanger regulation ratio and simple adjustment.
Three,Electric three confluence, shunt valveThe main features:
1, the fluid in flow state on the spool direction, so the working stability is good.
2, in addition to the valve cover at the guide bushing, the spool side and the valve seat surface also has a guiding role, oriented area, reliable work.
3, servo amplifier with depth dynamic negative feedback, can improve the accuracy of regulation.
4, electric operation in various forms, can be applied to 4 ~ 20mA.DC or 0 ~ 10mA.DC.
5, the electronic type electric control valve control valve opening directly from the current signal without servo amplifier.
6, automatic save investment, compared with single, double seat or sleeve valve, composed of the same system can dispense with a valve, simplifying the system, saving investment.
7, bellows seal type to form a complete seal for moving the valve stem, fluid leakage blocking must.
