What is Pressure Maintaining Control Valve?
A pressure sustaining control valve is a type of valve used to maintain a constant downstream pressure in the piping system. These valves are commonly used in systems where downstream pressure is critical to system operation, such as fire sprinkler systems or process control systems.
Pressure sustaining control valve; It is designed to keep the inlet pressure constant. When the system pressure exceeds the set pressure, the valve opens and ensures that the inlet pressure remains constant. It is not affected by pressure fluctuations and keeps the inlet pressure constant. It is mounted at the outlet of the filter in filtration systems and ensures efficient backwashing of the system.
How Does the Pressure Maintaining Control Valve Work?
The pressure sustain control valve works by regulating the flow of fluid through the valve in response to changes in downstream pressure. When the downstream pressure drops below a certain set point, the valve opens to allow more fluid to flow, increasing the downstream pressure. When the downstream pressure rises above the set point, the valve closes, reducing the fluid flow and keeping the downstream pressure at the desired level.
Pressure stabilizer control valves are used in conjunction with a pressure regulator or control valve to ensure that the downstream pressure remains within a specified range. They can be controlled manually or automatically using a control system to monitor and adjust valve position based on changes in downstream pressure.
What is a Control Valve?
control valve; A valve used to control fluid by changing the size of the flow passage as directed by a signal from a controller. Control valves provide pressure, temperature, flow and level control in all processes where fluid is present. Control valves are used for cold water, hot water, steam, superheated water, steam and gas etc. produced by consuming energy in enterprises. It ensures that the fluids can be transported and controlled without any loss.
- It works with mains pressure and does not need any extra energy.
- It has a fairly easy maintenance process.
- Classifies the pressure zones according to their importance.
- It performs the filling of the line in a controlled manner in inclined systems.
- It has a pressure stabilization feature without being affected by pressure and flow changes in the system.
