FLS gate valve

FLS (Flow Limiting and Shut-off ) valves

A flow-limiting shut-off valve. It has dual functions, being able to limit the flow of fluid within a certain range and completely cut off the flow of fluid when necessary.

The structure is relatively complex and usually contains components such as flow sensors, controllers and actuators. The flow sensor detects the flow of fluid and transmits the signal to the controller. The controller controls the actuator according to the preset flow limit to adjust the opening degree of the valve to achieve flow limitation or shut-off function.
