Pneumatic sleeve control valve
The pneumatic diaphragm sleeve control valve is composed of a sleeve valve body and a pneumatic actuator. The fluid channel of the compact sleeve control valve is in an S-shaped streamlined shape, with low pressure drop loss, large allowable pressure difference, low noise and large flow capacity. The compact sleeve control valve is widely used for precisely controlling media such as gas, liquid and steam, and keeping process parameters like pressure, flow rate, temperature and liquid level at the set values. It adopts a balanced valve core structure, with small axial unbalanced force, large allowable pressure difference and good stability. It is particularly suitable for occasions with large flow rate, large pressure difference and not high leakage requirements.
