Self-acting dynamic balance valve for stable flow control in systems

Short Description:

The ZLF self-operated balance valve is a type of valve that uses the pressure change of the medium itself for self-regulation, thereby maintaining a constant flow rate through the controlled system. It features flow indication and can be adjusted online, suitable for non-corrosive media such as heating and air conditioning systems. Through one-time testing and adjustment before operation, the system flow can be automatically fixed at a pre-set value. This valve offers accurate flow regulation, simple operation, stable operation, reliable performance, and a long service life.
