Q71F Wafer Ball

Shanghai Valve Manufacturing Co., Ltd. crown ring on the clip-ball, Q71F wafer compared with ordinary ball valve, structural length short, light weight, easy installation, saving materials and other significant advantages. Wafer insulation jacket valve insulation effect is good. In addition, seat with elastic sealing structure, reliable sealing, open and close easily. With a fire-resistant structure, in case of fire, it is still able to operate reliably and has a good seal. I. Product Overview: Compared with ordinary ball, "Crown Central" brand ultra-thin ball has structural length short, light weight, easy installation, saving materials and other significant advantages. Wafer insulation jacket valve insulation effect is good. In addition, seat with elastic sealing structure, reliable sealing, open and close easily. With a fire-resistant structure, in case of fire, it is still able to operate reliably and has a good seal. According to user needs, it can be provided with anti-static structure. Setting the 90 ° switch hole positioning pieces, if necessary can be locked to prevent misuse.
