Fully Welded Ball Valve

MODEL BALL VALVE-DN100-PN25-WE

Lever operated floating-ball valve for district heating and cooling mains. Forged carbon steel body (ASTM A105 / P235GH) with a PTFE seat, welded ends and a stem sealed in both directions — DN15 to DN1400 at PN25. No flange and no gasket sits inside the pressure boundary, which is why these valves stay tight in chambered and directly buried sections of a heat network.
