  • Introduction
  • Technical Parameters

Electric sleeve control valve

Composed of a valve body, a valve seat, a sleeve, a valve core, a guide sleeve, a valve cover, and Seal packing and Electric Actuator. Electric sleeve control valve receives the signal of the industrial automation control system (such as: 4~20mAor1~5V) to drive the valve to change the cross-sectional area between the valve plug and the valve seat to control the process parameters such as the flow, temperature and pressure of the pipeline medium. Automated adjustment function. Electric sleeve control valve fluid channel into S-type, low pressure drop, flow, Flow characteristics of high precision, Adjustable range wide. It is a high-characteristic electric control valve for fluids of various pressures and temperatures and for applications where leakage is not critical. The Electric sleeve control valve has the characteristics of sensitive action, simple connection, large flow, small size and high adjustment precision. Electric sleeve control valve is widely used in automatic control systems of electric power, metallurgy, petroleum, chemical, pharmaceutical, boiler, light industry and other industries.
