A pressure activated valve apparatus for axial in-line positioning within sanitary systems, such as steam lines for food processing, in which the entire apparatus, including the spring biasing and valve elements are positioned within the flowing media. The spring biasing element is protected from contact with the flowing media, through the use of a sealed fluid-dynamic cover so as to allow the passing media to flow over it with a minimum amount of resistance. The entire apparatus is connected to an incoming and an outgoing conduit so as to enable easy removal for replacement or maintenance purposes, with a minimum amount of cost and effort. A fluid-dynamic cover is fitted over portions of the valve assembly to isolate same from the fluid itself, while being removable to enable facilitated replacement or maintenance of the internal valve actuation parts.

An in-line pressure activated valve apparatus for integration into sanitary fluid conveyance systems for alternatively blocking and releasing the flow of said fluid therethrough, relative to the level of fluid pressure within said system, said apparatus comprising: substantially cylindrical housing
An in-line pressure activated valve apparatus for integration into sanitary fluid conveyance systems for alternatively blocking and releasing the flow of said fluid therethrough, relative to the level of fluid pressure within said system, said apparatus comprising: substantially cylindrical housing means having a first end at which said fluid is introduced through first aperture means and a second opposite end having second aperture means at which said fluid is alternatively blocked and released, said first end being operably attached to first incoming conduit means and said second end being operably attached to second outgoing conduit means, with said cylindrical housing means being positioned wholly axially and in-line between said first and said second conduit means, said cylindrical housing means further comprising internal fluid passage means, about the longitudinal axis of said cylindrical housing means, for permitting said fluid to flow between said first and second opposite ends of said cylindrical housing means, said cylindrical housing means further comprising substantially concentrically positioned outwardly protruding valve attachment means operably secured to said first end of said cylindrical housing means for operable positioning within a portion of said first incoming conduit means, valve means operably and springedly attached at said valve attachment means for reciprocation within and through said cylindrical housing means, said valve means comprising a valve stem member having a valve head at said first incoming end and a valve closure at said second outgoing end, opposite said first end, as well as spring biasing means operably interposed between said valve means and said cylindrical housing means, to enable biased reciprocation of said valve stem member to, in turn, seat and unseat said valve closure within said second aperture means, at said second end of said cylindrical housing means, to alternatively restrict and release, respectively, the flow of said fluid passing through said internal fluid passage means of said cylindrical housing means, said spring biasing means being operably interposed between said valve attachment means and said valve stem valve head, said level of fluid pressure serving to bear against said valve closure to overcome and compress said spring biasing means to unseat said valve closure from its seated position upon attaining a pre-determined pressure to, in turn, release said fluid from said second aperture at said second end of said cylindrical housing means, said spring biasing means co-operating with said valve closure to seat same against said second aperture to block the flow of said fluid through said internal fluid passage means of said cylindrical housing means until said spring biasing means is overcome by said pre-determined pressure of said fluid therewithin said cylindrical housing means, said spring biasing means further being longitudinally positioned axially and in-line with said cylindrical housing means, and located upstream of said cylindrical housing means within said first incoming conduit means, sealed secondary housing means operably and sealably attached to and about said outwardly protruding valve attachment means for isolating said spring biasing means, said valve head, and said valve attachment means from undesired contact with said fluid passing thereabout, said secondary housing means comprising a substantially fluid-dynamic shaped member to minimize resistence to the flow of said fluid passing from said first incoming conduit means through and into said pressure activated valve apparatus, said secondary housing means further being fixedly sealed, yet removably attachable to the outer periphery of said valve attachment means to enable facilitated access to said spring biasing means and said valve head for maintenance and replacement of same.
