These valves work to release overpressure in a piping system or a vessel. Spire offers these kinds of valves as a solution for the automatic release of pressure from boilers, pressure vessels or other systems when the pressure or temperature exceeds preset limits.
A pressure safety valve is characterized by rapid opening and closing and normally used to relieve compressible fluids. These valves are used for gas, air, and steam. Its main use is to relieve the pressure from systems such as boilers, autoclaves, compressors, steam generators, pressure vessels and air or gas pipelines.
A pressure relief valve characterized by gradual opening or closing, generally proportional to the increase or decrease in pressure system. This type of valves is used on non-compressible fluids service. Its purpose is to release overpressure, protecting the equipment or system from damage. It is commonly used in tanks, pipelines or other vessels where a big relief capacity is not required.
