Abstract
A pressure relief valve controller (PRVC) includes a housing having a spring, a spring seat connected to the spring, a piston, and a portion of which is disposed between the spring seat and the piston, wherein one or more grooves and/or protrusions are disposed on at least one of the spring seat or the piston. The diaphragm can conform to the one or more grooves of the spring seat thus preventing diaphragm rupture due to excess pressure without affecting calibrations of current PRVCs.
