Overview

Electric regulating ball valve is a type of ball valve with a 90 ° angle; #176; The rotary ball valve is composed of angular stroke electric actuators (DY, 3810R, DZW, DQW, QT) and a ball valve body. The electric regulating ball valve is suitable for situations where two positions are cut off and adjusted. It adopts an integrated structure, and the electric actuator has a built-in servo system, without the need for a separate servo amplifier. It can be controlled by inputting a 4-20mA control signal or 1-5VDC and 220VAC power supply. Electric regulating ball valves have the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable action, etc.

Product Details

Electric regulating ball valve is a type of ball valve with a turning angle of90°The rotary ball valve adopts an angular stroke electric actuator(DYThe3810RTheDZWTheDQWTheQT)Composed of ball valve body. The electric regulating ball valve is suitable for situations where two positions are cut off and adjusted, and adopts an integrated structure,Electric actuatorBuilt in servo system, no need for additional servo amplifier, input4-20mAControl signal or1-5VDCand220VACThe power supply can control the operation. Electric regulating ball valves have the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable action, etc. This electric regulating ball valve is particularly suitable for applications where the medium is viscous, contains particles, or has fibrous properties. Currently, it is widely used in various fields such as petroleum, chemical, metallurgical, light industry, papermaking, power plants, and refrigeration.
