[Valve features]
The electronic single seat control valve consists of an electronic electric actuator and a single seat valve, suitable for small pressure conditions. Electric actuator built-in servo system, no need to add servo amplifier, input signal and power supply can control the operation. The structure is compact and the fluid channel is S streamlined. The utility model has the advantages of small size, light weight, small pressure loss, large flow rate, large adjustable range, high flow characteristic precision, etc.. Application of precise control of small flow. Such as fine chemicals, food additives, medical flowers, electronics industry.
[Adaptive condition]
The utility model relates to an electric sleeve regulating valve which is composed of a direct stroke electronic type electric actuator and a straight through single seat valve. Embedded servo function, standard signal 4-20mA or 1-5V accept a unified DC, the current signal into linear displacement corresponding to the automatic control valve opening, continuous adjustment of the fluid in the pipeline pressure, flow, temperature, level and other parameters. Applicable to leakage requirements strict, low pressure before and after the valve, and a certain viscosity and contain a small amount of fiber media.
