Digital lock balancing valve is a kind of external regulation valve with digital lock special functions,adopts DC type valve body better equal percentage flow structure,has characteristic, allocate to reasonably heating (air bandwidth,effectively solve the conditioning) room temperature is uneven and that exist the system.Can in problems accurately adjust the pressure drop and flow, at the same time to improve fluid flow state in pipeline system,achieve the goal of pipeline fluid balance and save the source of the instructions, opening of the valve opening locking devices and a small valve used for flow measurement of pressure,as long as in the selection and user entry fitted with appropriate balance the valve,with specifications of intelligent for the instrument special disposable lock after debugging,the system of the total water control in a reasonable range, unreasonable temperature phenomenon,This product is the ideal product in the heating system.Can be installed on the water supply pipe,also can be installed on the return pipe,generally we recommend installed high pipe,especially for the return on facilitate order to temperature in loop,debugging,more on the return pipe is loaded, installed the balancing valve for (back) to the pipe don't have to set a cut-off valve.
