What is level control valves?

Level control valves are used to maintain a constant water level in a tank or reservoir. They are typically used in water treatment plants, wells, and fire protection systems. These valves are designed to monitor the fluid level in a given application and adjust the flow of water into or out of the tank to maintain a constant level.

There are several types of level control valves, including float-operated level control valves, pressure-operated level control valves, and electronic level control valves. Float-operated valves use a weighted float attached to a valve stem to control water flow. Pressure-operated valves use pressure sensors to detect changes in water level and adjust valve position accordingly. Electronic level control valves use sensors and electronic control systems to monitor and adjust water levels.

Level control valves can be configured to be either normally open or normally closed. In a normally open configuration, the valve is open when there is no power to the valve. In a normally closed configuration, the valve is closed when there is no power to the valve.

Overall, level control valves play a critical role in maintaining water levels in a variety of applications and are an essential component of many water supply systems.
