Product Description

Overview of Pneumatic Diaphragm WCB Carbon Steel Modulating Control Valve:

Pneumatic diaphragm WCB carbon steel modulating control valve are automatic control devices powered by compressed air, mainly used for precisely regulating the pressure, flow rate, temperature and liquid level parameters of media such as gas, liquid and steam. The pneumatic diaphragm WCB modulating valve adopts a top-guided structure and is composed of a multi-spring pneumatic diaphragm actuator and a low-flow-resistance single-seat valve body. The height and weight of the actuator are both reduced by 30%, featuring sensitive operation, compact structure, and easy disassembly and assembly. The pneumatic diaphragm carbon steel control valve body adopts an S-shaped flow channel design and is optimized through fluid analysis, featuring low pressure drop loss and large valve capacity, with an adjustable ratio of up to 50:1

 

 

The Principle Of Pneumatic Diaphragm Carbon Steel Modulating Control Valve:

Pneumatic diaphragm WCB carbon steel modulating control valves are widely used to precisely control the process parameters of gases, liquids and other media, maintaining pressure, flow rate, temperature and liquid level at the given values. Pneumatic diaphragm carbon steel modulating control valves are particularly suitable for applications where the allowable leakage is small and the pressure difference before and after the valve is not significant. The leakage standards of pneumatic diaphragm WCB control valve are classified as Grade IV or Grade VI, and the flow characteristics of pneumatic diaphragm WCB carbon steel flange control valves are linear or equal percentage. Pneumatic diaphragm WCB carbon steel modulating valves come in a wide variety of types and specifications to choose from.
