Balance the design of the pneumatic valve type selection

of design model selection of products, generally in the network of branch point, thermal entrance, indoor riser should design, installation of dynamic balance of pneumatic valve, in order to improve system control performance.
and selected reference ( The main installation dimensions and performance parameters of the table) And ( On balance type pneumatic valve selection chart) , the design discharge elected on the coated
black portion of the figure.
and dynamic balance of pneumatic valve can be installed on the water supply pipe, also can be installed on the return pipe. When the system fluid pressure exceeds radiator allows working pressure
, to be on the safe side, dynamic balance pneumatic valve should be installed on the water supply pipe.
, the highest use temperature ℃, nominal pressure. MPa。
, suitable range of differential pressure: ~ Kpa. When the system fluid differential pressure exceeds Kpa, to prevent noise, measures should be taken to the
the excess pressure difference consume.
, pneumatic valve does not have shut off the function of dynamic balance, according to the need to be up to snuff out valve.
and choose DN ~ pneumatic valve DN caliber dynamic balance, must mention the connection mode.
