Electric Sleeve Control Valve

Electric sleeve control valve consists of a straight-travel electric actuator and a globe valve body. With built-in servo unit for receiving the signal of 4-20mA or 1-5VDC, and transform the current signal into corresponding straight travel displacement, automatically modify the opening of the valve to continuously control the pressure, flow rate, temperature and liquid level in the pipeline, Temperature, level and other process parameters of continuous adjustment.

Electric sleeve control valve is widely used due to its good stability and easy maintenance. It can be designed into the balance type to eliminate the static imbalance force on the valve disc, and has a certain damping effect, which can reduce the vibration caused by the fluid flow, which can serve process condition with high differential pressure.
