DIN Ball Valve
DIN Ball Valve is a straight‑through floating ball valve. Its valve body can be one‑piece, two‑piece or three‑piece type, and the valve body is fully made of stainless steel or carbon steel. The closing member of flanged ball valve is a perforated ball (or partial ball). The ball rotates together with the stem to realize valve opening and closing. Ball valves are mainly used in pipelines for shut‑off, diversion and changing medium flow direction. The ball of flanged ball valve is floating. Under medium pressure, the ball will produce certain displacement and press tightly against the sealing surface at outlet side to guarantee outlet‑side sealing. Among various valves, ball valve features low flow resistance. When the ball valve is open, ball passage, valve body passage and connecting pipe diameter are aligned at the same size, medium can flow through with almost no pressure loss. Soft‑seal and hard‑seal seat options are available.
