Abstract
A one piece valve body incorporates a built in strainer and a ball valve which can be used for cleaning out the strainer without any disassembly, and also serves the purpose of the manual drain that has to be in the system for code. Also the orifice to the valve is mounted on top of the strainer so gravity will help in keeping any debris that might get through the filter screen from entering and causing the valve to fail. The design of the inlet is such that a chamfer is machined on the inside so a standard female swivel fitting can be installed without adding a separate union. This valve body design can work for both direct acting or diaphragm operated valves.
