Q71F Wafer type flanged ball valve

Q71F Wafer type flanged ball valve introduction
Q71F Wafer type flanged ball valve has the advantages of short structure length, light weight, convenient installation and material saving.Q71F Wafer type flanged ball valve is suitable for short line pipe and special space installation and use, with compact structure,short length,small volume, Q71F Wafer type flanged ball valve seat and flange end face distance is close, less material retention, superior sealing performance and other characteristics.

Q71F Wafer type flanged ball valve seat use the elastic sealing structure, the sealing is reliable, opens and closes easily.With fire-resistant structure, in case of fire,Q71F Wafer type flanged ball valve can still operate reliably and have good sealing. According to the needs of users, anti-static structure can be set.The switch with hole positioning plate is set, which can be locked according to the need to prevent misoperation.

Q71F Wafer type flanged ball valve choose different material, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media.
