TECHNICAL DESCRIPTION
SAFETY OVERFLOW VALVES TOSACA MODEL 1216
• Dimensioning – EN-4126-1 / 7
• Structural design: EN-12516-1, EN-4126-1 / 7,
DIN 259 and ANSI B2.1
• Materials – Stainless steel 316 L and duplex steels.
• Temperature range -30ºC to +350ºC.
• Cryogenic operation -196ºC
• Tests – EN-4126-1 / 7
• Tolerances EN-4126-1 and ASME UG-126
PRINCIPLE OF OPERATION
Automatic safety valve that opens proportionally to pressure rise. The constant force between the pressure force and the reaction of the closing spring ensures minimal flow, respectively minimal fluid loss when the valve is actuated.
WORKING FLUID / MEDIUM
Steam, gases, gas vapors and liquids
OPTIONS
• Possible housing materials: stainless steel, duplex steels
