Product features

The valve body of ZDLS electronic electric angle control valve is a right angle type, which is specially used at the 90 degree bend joint where the medium is viscous, easy to crystallize, contains suspended particles, and there is no dead angle in the angle type valve body, which is easy to purge and easy to maintain. It is widely used. Electronic electric angle regulating valve generally adopts single seat or balanced sleeve valve disc, with servo amplifier inside. Input control signal (4-20mADC or 1-5VDC) and power supply to control the valve opening, so as to achieve the regulation of pressure, flow, liquid level, temperature and other working parameters. In some high differential pressure situations, multi-level regulation can also be achieved.
Angle control valve
Features of electronic electric angle regulating valve:
 
The electric angle control valve has the advantages of compact structure, light weight, sensitive action, streamlined fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient disassembly and assembly, etc. It is widely used for precise control of gas, liquid and other media. Process parameters such as pressure, flow, temperature and liquid level are kept at a given value. It is especially suitable for the adjustment of high viscosity, suspended solids and granular substances, which can avoid coking and blocking, and facilitate the combination of self-cleaning and cleaning.
