A product profile of the pneumatic valve Q71F wafer ball

QF wafer ball summary of pneumatic valve.
QF wafer ball valve pneumatic valve with reference to the characteristics of an Italian product, compared with the ordinary pneumatic valve ball, has the structure length is short, light weight, easy installation, saving materials and other significant advantages. In addition, pneumatic valve seat adopts elastic sealing structure, reliable sealing, easy opening and closing. In case a fire occurs in a equipped with refractory structure, one thousand, still can reliable operation and good sealing. QF wafer ball valve pneumatic valve according to user needs, can be equipped with anti-static structure. Setting the perforated ° switch position, according to the need can be locked, to prevent wrong operation.
