25/10/2011 · Every steam and hot-water heating boiler must have at least one safety or safety relief valve of sufficient relieving capacityto meet or exceed the maximum burner output. The ability of these valves to perform their intended function can be affected by several things, such as internal corrosion or restricted flow, which can prevent the valve from functioning as designed. Internal corrosion is probably the most common cause of "freezing" or binding of safety and safety relief valves. This condition is generally caused by slight leaking or "simmering" due to improper seating of the valve …

Your pressure safety valve is a direct spring-loaded pressure-relief valve that is opened by the static pressure upstream of the valve and characterized by rapid opening or pop action. When the static inlet pressure reaches the set pressure, it will increase the pressure upstream of the disk and overcome the spring force on the disk.
