Product Description:
ZAZQ and ZAZX electric tee combined and diverter control valves are guided by cylindrical thin-walled window-shaped spools. Equipped with DKZ linear stroke electric actuator, it accepts 0~10 or 4~20mA.DC signal to drive the valve to open and close. Among them, the three-way confluence control valve is used to mix two fluids into a third fluid, or the same fluid of different temperatures, mixed into the same temperature fluid. A three-way diverter splits a fluid into two streams.
The caliber of this series of products is from 25mm to 200mm, the nominal pressure is 1.0, 1.6, 4.0, 6.4MPa, the temperature range is -60°C to 450°C, and the control signal is 0~10 or 4~20mA.DC. The actuators with different actuators can be divided into two types: ordinary type and electronic type.
Product features:
The fluid is in the direction of action on the valve core, so the working stability is good.
In addition to the bushing guide at the valve cover, the side of the valve core and the inner surface of the valve seat also have a guiding effect, with a large guide area and reliable work.
The servo amplifier uses deep dynamic negative feedback for improved adjustment accuracy.
Electric actuators are available in a variety of forms, and can be applied to 4~20mA.DC or 0~10mA.DC
Electronic electric control valves can control the valve opening with a direct current signal, eliminating the need for a servo amplifier.
Save on automation investment, simplifying the system and saving investment compared to single, double or sleeve control valves.
The bellows seal type forms a complete seal on the moving valve stem, preventing fluid leakage.
