Sn51/52 series soft seal O type ball valve is a full straight through ball valve, the fluid pressure drop loss is the smallest, excellent cutting performance, the ball only need to rotate 90 degrees to achieve the full open or close valve, at the same time with the valve stem fly out, anti-static and other functions.
SN5 series soft seal ball valve is a full bore straight through ball valve, which was certified by API 6D in 2017 and API 607, TÜV ISO15848, BV SIL3 in 2019. This type of ball valve is available in floating and fixed types, and its ball only needs to be rotated 90° to achieve full opening or closing of the valve. The ball valve has excellent cut-off performance, minimal fluid pressure drop loss, as well as anti-flying out of the stem, and fire and anti-static features, suitable for liquid, gas and other fluid cut-off control.
