Vridspjällventiler 304Y RPTFEsäte (Butterfly Valve 304Y RPTFE Seat)
The 304Y high performance butterfly valve has a distinctive “J” shaped PTFE seat ring which does not detract from the rigidity of the valve mechanism, yet provides a more user friendly torque profile – but without sacrificing durability or leak tightness. In common with its stable companion, the 302Y, this valve complies with face-to-face ISO5752 and ISO5211 mounting flange requirements. Nominal Size: 40mm to 150mm, 200mm and 250mm to 300mm. Working Temperature Ranges: -20 C to +200 C.
