A bridge fitting for use with two or more surface mounted components includes a housing having at least a first port disposed on a first side of the housing, at least a second port non-coaxial with the first port and disposed on a second side of the housing opposite the first side of the housing, and an internal fluid passageway connecting the first and second ports. The internal fluid passageway is configured to limit fluid flow within the bridge fitting to a single path between the first and second ports.

Modular surface mount fluid system

The present invention provides for a bridge fitting for use in a fluid manifold system for being in fluid communication with two or more surface mounted fluid components having an inlet port and an adjacent outlet port. The invention also provides for a housing with a first port connected to a second port, with an internal fluid passageway joining the first and second ports and at least one projection extending from the housing. The bridge fittings may be mounted in a channel block having a groove and an aligned hole for receiving the projection. Another embodiment of the invention provides for a modular surface mount check valve with a valve body having a mounting flange connected thereto, the flange being substantially planar and having an inlet passage located about the center of the flange and an outlet passage located adjacent the inlet passage. The body further comprises a valve chamber in fluid communication with the inlet passage and the outlet passage, the chamber further comprising a valve seat formed at the juncture of the inlet passage and the chamber, and a poppet positioned in the chamber, and a spring mounted in the valve chamber for biasing the poppet towards the valve seat. The invention also provides an air actuated surface mount flow control valve comprising a valve body having a mounting flange connected thereto and the flange being substantially planar and having an inlet passage located about the center of the flange and an outlet passage located adjacent the inlet passage, the body further comprising a cavity in fluid communication with the inlet passage and the outlet passage, a stem positioned in the cavity, and a spring mounted in the cavity for biasing a first end of the stem in sealing engagement with the inlet passage and the outlet passage, the stem further comprising an internal fluid passageway in fluid communication with an actuator fluid compartment located under a lower surface of the stem, and the external source of pressure.

A sanitary diaphragm valve is provided that includes a generally dome shaped diaphragm having a central boss that can be connected to or driven by a valve actuator. The diaphragm includes an outer peripheral edge and a relatively thin web portion that connects the boss to the outer edge. In one embodiment, the web portion is arcuate or dome shaped. The thinner web portion permits the diaphragm to have an extended cycle life and to permit the valve to operate at higher fluid pressures. The thin web may be defined by two different contoured surfaces, one convex and the other concave, such as formed by two radiuses. A valve body is provided that includes a bowl shaped valve cavity. This valve cavity includes an outer vertical edge to permit more thorough cleaning and to eliminate entrapment areas. The valve assembly provides support surfaces for the diaphragm that reduces stress on the diaphragm particularly at higher operating pressures.

A poppet type excess flow valve comprises a body forming a valve chamber having a first portion of a first diameter adjacent a first end and a second portion of a second smaller diameter adjacent second end. A valve seat is located between the first and second portions of the valve chamber. A poppet element is mounted in the valve chamber and includes a first section in the form of a hollow cylindrical body extending into the second portion of the valve chamber and terminating therein in an open end. The outer diameter of the hollow cylindrical body section is only slightly less than the diameter of the second portion of the valve chamber for guided sliding movement therein. The poppet element further includes a second section located in the first portion of the valve chamber and including an end wall carrying a valving surface extending radially outward for cooperation with the valve seat. A compression coil spring maintains the poppet element continually biased under a predetermined force toward the inlet port, and flow passages are formed through the hollow cylindrical body portion of the poppet element at a location closely adjacent the valving surface.
