ZDLQ/ZDLX electric three way regulating valve, electric control valve, electric three way shunt, combined control valve adopts cylindrical thin wall window shaped spool guide. Equipped with DKZ direct stroke electric actuator, accept 0~10 or 4~20mA.DC signal to drive valve opening and closing. The three way combined regulating valve is used to mix the two fluids into third fluids, or the same fluid at different temperatures, and to blend into the same temperature fluid. The three way diverter valve divides a fluid into two fluids.
This series of products from 25mm to 200mm, nominal pressure of 1, 1.6, 4, 6.4MPa, the temperature range of -60 to 450 degrees Celsius, the control signal is 0~10 or 4~20mA.DC. With different executive agencies can be divided into two types of ordinary and electronic.
 
Product features
 
The flow direction of the spool is in the open flow state, so the work stability is good.
In addition to the valve cover bushing guide, the valve side and the valve seat internal surface also has a guiding role, the guide area is large, reliable work.
Servo amplifier uses deep dynamic negative feedback, which can improve the adjustment precision.
The electric manipulator has many forms and can be applied to 4~20mA.DC or 0~10mA.DC
Electronic motor control valve can direct current signal to control valve opening without servo amplifier.
Save investment in automation, compared with single seat, two seat or sleeve control valves, the same system can save a valve, simplify the system, save investment.
The bellows seal forms a complete seal to the moving stem, and the fluid leaks outward.
