Single seat regulating valve

Single seat regulating valve refers to the structural form between the valve body and the valve seat of the regulating valve, which forms the inlet and outlet seals of the valve with a valve core sealing surface and a valve seat sealing surface. Single seat regulating valves can be divided into electric, pneumatic, and hydraulic types, and flow characteristics can be divided into linear characteristics and equal percentage characteristics. A single seat regulating valve is an instrument valve device used for flow control. It has a large unbalanced force and allows for a smaller pressure difference than a double seat valve. When there is a high pressure difference and a large diameter, it is best to equip it with a valve positioner. The single seat regulating valve produced by Shanghai Meiyanyi Pump Valve has the characteristics of small volume, small leakage, flexible and reliable action. It consists of a pneumatic or electric valve actuator and a valve body. It uses compressed air or a motor as the driving force to receive pressure signals from the control system, and adjusts the flow rate of the medium in the pipeline according to the proportion of signal changes, realizing the automation process of production control.
