Fluid control valve

A fluid control valve, comprising:

• a housing body including
• a pipe part having a flow passage therein;
• and
• a valve housing part including a valve chamber, a valve opening, a pair of flat surfaces and an open end, wherein the valve housing part has a central axis oriented perpendicular to a central axis of the pipe part such that the central axis of the valve housing and the central axis of the pipe part extend along a plane, the valve opening fluidly communicating the valve chamber with the flow passage, wherein the pair of flat surfaces are disposed on opposite sides of the plane, wherein each of the pair of flat surfaces extends perpendicularly toward the plane;
• wherein the valve housing part comprises a cylindrical shape having a bottom wall and a top, wherein the bottom wall separates the pipe part from the valve housing part, wherein the open end is positioned on the top, wherein the pair of flat surfaces are positioned on the bottom wall, and wherein the valve opening passes through the bottom wall, between the pair of flat surfaces;
• a valve member housed in the valve chamber and configured to open and close the valve opening;
• a cap closing the open end of the valve housing part, wherein the open end is positioned axially between an upper most surface of the cap and the pair of flat surfaces with respect to the central axis of the valve housing part;
• and
• a spring disposed between the valve member and the cap, wherein the spring biases the valve member toward the valve opening.
