Abstract
A flow regulator with pressure relief combination valve is disclosed which can include a housing and a valve assembly. The housing can have a chamber and four ports. A cage, having a plurality of cross holes, is supported by the housing. A hollow spool is slidably disposed within the cage and is biased to engage the cage. A shoulder of the cage and a counterbore of the spool cooperate to interferingly retain an insert. A poppet is slidably disposed inside of the cage. The valve assembly includes an adaptor, a spring disposed within the adaptor, a guide disposed between the spring and the poppet, and an adjuster adjustably secured to the adaptor. The spring is arranged to bias the poppet against a seat via the guide. The adjustor is movable to adjust the position of the spring.
