overview
ZL47F-16 Self OperatedBalance valveMainly through an automatic processadjustvalvePetals andmanual control valveComposed of petals. Using the pressure changes of the medium itself as power, it automatically adjusts the balance of flow in each branch pipeline, accurately stabilizes the flow, and has functions such as opening indication, locking, and closing. Suitable for flow control of non corrosive media such as heating and air conditioning. By adjusting it once before operation, the system flow can automatically remain constant at the required set value.
