The product description
KPF balancing valve is a kind of external regulation valve with special functions, has good flow characteristic, to reasonably allocate flow, implementation flow quantitatively, can effectively solve the heating (air conditioning) room temperature is uneven and problems that exist in the system. Because the valve is equipped with locking device and the open degree of instructions and the opening used for flow measurement of pressure valve, so as long as in the selection and the user entry fitted with appropriate specifications of the balance valve, with special intelligent instrument for the disposable lock after debugging, the system of the total water control in a reasonable scope, thus overcome the "big flow rate, small temperature difference" unreasonable phenomenon.
