Stainless Steel Pneumatic Or Electric Flow Diversion Flow Regulating Valve
Regulating Valve Introduce
Pneumatic regulating valves are a type of valve used to control the flow of fluids in industrial systems. They are operated using compressed air, which is used to actuate the valve stem and control the position of the valve plug or disc.
These valves are commonly used in process industries such as oil and gas, chemical, and petrochemical, as well as in power generation and water treatment plants. They are used to regulate flow, pressure, and temperature of fluids, and can be used in conjunction with control systems to achieve precise control and ensure safe and efficient operation.
Pneumatic Regulating Valve principle
The principle of a pneumatic regulating valve is to control the flow, pressure, or temperature of fluids in a system using compressed air. The valve is actuated by a pneumatic actuator that converts the compressed air into mechanical motion, which is used to position the valve plug or disc and adjust the flow of fluid.
The control signal for the pneumatic actuator is typically provided by a control system, which monitors the process variables and adjusts the valve position accordingly. For example, if the flow rate of a fluid needs to be increased, the control system will send a signal to the pneumatic actuator to open the valve further, allowing more fluid to pass through.
The valve plug or disc is designed to provide precise control over the flow of fluid, with different valve types and designs suitable for different applications. Globe valves, for example, are commonly used for precise flow control, while diaphragm valves are often used in applications where cleanliness is important.
