Material:
cast iron, steel, stainless steelDimensions:
DN 15 - 400TECHNICAL CHARACTERISTICS
SAFETY RELEIF VALVE TOSACA MODEL 1400
• Calculation - EN-4126-1 / 7
• Design EN-12516-1, EN-4126-1 / 7
• Material standards - EN / ASTM
• Tests - EN-4126-1 / 7, MSS-SP-55
• Tolerance EN-4126-1 and ASME UG-126
WORKING PRINCIPALS
Automatic safety valve opens proportional to pressure rise. The constant tension between the force of pressure and the closing spring response provides a minimum flow, which means minimal loss of fluid when the valve is actuated.
MEDIA
Steam, gases, vapours, fluids
OPTIONS
• Available body materials: ductile iron, carbon steel, stainless steel, LCC, duplex and super duplex steels
• Available seat materials: metal / metal, PTFE, Viton and Stellite
