Type 1700 Maxiflow Safety Valve

The Consolidated 1700 series Maxiflow safety valves are field-proven and are designed to provide optimum boiler overpressure protection. Increases plant efficiency by reducing steam losses via improved seat tightness and rapid opening to full lift with rapid closing as vessel pressure is reduced. 

Features:

• Side rod construction provides extreme temperature compensation for thermal expansion of the body for a more consistent spring load – improved seat tightness

• Thermodisc thin flexible design for repeatable seat tightness 

• Cover plate provides faster full lift by rapid venting 

Applications :

The Consolidated 1700 series Maxiflow safety valves are used extensively in sub-critical, drum type boilers and super-critical, once-through boilers. Inlet pressure ratings from ASME 600 class thru ASME 4500 class.
