The magnetically retained pressure relief valve is a significant improvement of standard spring mechanism pressure valves. Valve eliminates the need for a spring by instead incorporating magnets to hold the poppet relief valve in the closed position. The technology utilizes magnets to open the relief valve by harnessing the magnetic field decay between the two magnets when separated. This leads to a faster acting valve that does not require an increasing force to open the relief valve after cracking pressure has been surpassed, as is the case in standard pressure relief valves.
The magnetic pressure valves includes a housing having a fluid inlet and at least one fluid outlet. There are two magnetic structures in the housing of the valve, which are magnetically attracted to one another. One magnetic structure is immovable and affixed near the fluid inlet. The other magnetic structure is coupled to a piston. The size of the outlet chamber(s) is defined by the piston’s stroke.
