Number-lock Balance Valve

MstnLand's series of number-lock balance valves is a kind of static hydraulic balance valve. It has an equal percentage flow characteristic curve, suitable for centralized volume regulation, centralized quality regulation and phased change of flow volume regulation system. When the system flow changes, the flow of each branch and each user will increase or decrease proportionately, keeping the flow distribution scheme at the initial adjustment.
