A42Y-1000 Full-Open High Pressure Safety Valve

A42Y-1000 is suitable for equipment and pipelines handling water, non-corrosive oils, and other mediums with operating temperatures ≤ 200°C, serving as an overpressure protection device.

A safety valve is a shut-off device that remains in a closed state under the influence of external forces. When the pressure of the medium inside the equipment or pipeline exceeds the specified value, it prevents the pressure inside the pipeline or equipment from exceeding the specified limit by discharging the medium to the outside of the system. Safety valves belong to the category of automatic valves and are mainly used on boilers, pressure vessels, and pipelines to control the pressure within the specified limits, playing a crucial protective role in ensuring personal safety and equipment operation. Note that safety valves must pass a pressure test before they can be used.

The fully open high-pressure safety valve has an opening height less than 1/4 of the duct diameter, usually between 1/40 to 1/20 of the duct diameter. The micro-open safety valve operates in a proportional manner and is primarily used in liquid applications, and sometimes in applications involving very small gas flow rates.
