How to select sanitary valves?

There are many types of sanitary valves, so how should we select them? The following sanitary valve manufacturers will summarize the selection methods of sanitary valves.

Sanitary valves are the main regulating equipment for flow regulation of heating system, and other regulating valves are auxiliary equipment, so sanitary valves are necessary. If a heating system is not equipped with temperature control valve, it can not be called heat metering and charging system. In the design of sanitary valves, correct selection is very important. The selection purpose of sanitary valve is to determine Kv value (flow coefficient) according to the design flow (under known heat load) and allowable resistance drop; Then determine the diameter (model) of the temperature control valve from the Kv value. Therefore, the relationship between Kv value and diameter must be given in the design atlas or manufacturer's samples, otherwise it is not convenient for designers to use.

In the selection and design of sanitary valves, it is by no means a simple selection of sanitary valves with the same diameter as the pipeline. But in the process of type selection, it is necessary to create an ideal differential pressure working condition for the selected sanitary valve. The normal working pressure difference of a sanitary valve is between 2 ~ 3mh2o, no more than 6 ~ 10mh2o. Therefore, the preset value range of sanitary valve must be given to prevent noise from affecting the normal operation of sanitary valve. When there are more than two diameters under the same Kv value, the sanitary valve with small diameter shall be preferred to improve the regulation performance of sanitary valve.

The above is the selection method of sanitary valve summarized by the manufacturer of sanitary valve.
