SuperJet safety valves are used on industrial steam boilers rated at least how many psi?

• A. 1500
• B. 500
• C. 3000
• D. 3500

Answer: (C)

Safety valves protect boilers by releasing steam when pressure reaches the set point, preventing overpressure. The SuperJet line is a high-capacity relief valve tailored for industrial boilers operating at very high pressures. It is specified for boilers rated at least 3,000 psi because, at that level, the valve’s large flow capacity and robust design are needed to vent enough steam quickly and reliably to keep the boiler from exceeding its maximum allowable pressure. For lower-pressure boilers, smaller or different relief devices are used, so 3,000 psi is the threshold for this valve type.
