• Valve body, valve cover: A105, F22 • Valve seat: Martensitic stainless steel • Valve disc: Martensitic stainless steel • Bimetallic: chromium-nickel stainless steel • Other internal parts: stainless steel	Design pressure (PMA): • TB51: 110bar • TB61: 160bar • TB71: 160bar • TB82: 320bar	Maximum operating pressure (PMO) @ maximum operating temperature (TMO) • TB51 type: 65bar@399℃ • TB71 type: 105bar@510℃ • TB81 type: 150bar@540℃
Notice
It is best not to insulate the steam trap and the area within 1m of its front end. If the steam trap is to be discharged to the atmosphere, it must be discharged to a safe place, because the temperature of the discharged condensate may be 100°C.
