Abstract
A header pipe has an external sealing surface. A diaphram type control valve is externally mounted to the header pipe. An outlet pipe is mounted to the header pipe, enters and crosses the flow passage in the header pipe, and has a threaded end. The body of the control valve has a skirt which bears against the sealing surface, and a tube which is threaded onto the threaded end of the outlet pipe to mount the valve and to bring the skirt against the sealing surface. A peripheral seal fits between the skirt and the sealing surface. It may be a cup-sectioned seal which is pressure-biased to form the seal.

In combination:
- a header pipe having an internal flow passage, a wall with a sealing surface, and an aperture through said sealing surface into said flow passage;
- an outlet pipe mounted to and passing through said wall, crossing said flow passage and having a threaded end;
- a diaphragm-type valve having a body which includes a peripheral skirt adapted to bear against said sealing surface, a web, a threaded tubular member supported by said web threadedly engaged to the said end of said outlet pipe and operative to bring said skirt toward and against said sealing surface, thereby to mount said diaphragm-type valve to said header pipe, said web providing a fluid passage extending between said flow passage and said outlet pipe, said diaphragm-type valves being disposed outside of said header pipe, a valve seat and a valving diaphragm in said body in fluid controlling position between said end of said outlet pipe and said fluid passage, and port means for admitting control pressure to said diaphragm;
- and
- peripheral seal means disposed and sealing between said skirt and said sealing surface.
