HG8303 series automatic flow control valve consists of a preset flow control valve and an actuator. It is designed for non-corrosiveliquid flow control in pipelines.
The automatic control valve has pressure balancing function and high sensitivity. It features low noise, enhanced reliability, modular structure design, and is maintenance free. Through the throttling valve and according to the standard drawing, it supports fast and convenient flow adjustment. The automatic flow control valve can also be used for many more control purposes through combining with other functional units.
