3-Piece Flanged Cast Steel Ball Valves
3-Piece Flanged Cast Iron Ball Valve
3-piece flanged cast iron ball valve; comprises two flanged end pieces and a centre body, with grey cast iron (GG-25) or ductile iron (GGG40) body, stainless steel ball and full bore design. Since the ball bore equals the pipe inner diameter, pressure loss when open is minimised; used as a main isolation valve in heating, hot water, cooling and industrial water lines.
Available in sizes DN15 to DN300, pressure classes PN16 and PN40. Operates to +180 °C to +200 °C depending on model, with PTFE seats. Manufactured to TS 3148 standard; flanges conform to TS EN 1092. Models with ISO 5211 top flange are suitable for pneumatic or electric actuator mounting.
