This type of product consists of a single-seat control valve component, a sleeve adjustment valve component and an electronic electric actuator. The adjusting valve component adopts the top guiding type structure, and the single seat regulating valve is suitable for occasions with low pressure difference and strict leakage requirements; the sleeve valve is suitable for occasions with low noise and large pressure difference. By changing the valve seat type, the leakage can be increased. The electronic electric actuator receives the adjustment instrument or computer control signal without the need for additional servo. This kind of products are widely used in metallurgy, electric power, petrochemical and other industrial sectors for fluid flow, pressure, Temperature and liquid level control.
