Abstract: A valve handle that operates a valve, and includes permanent, integral labeling. The labeling includes installer information about the installer of the valve handle, including the installer's name and contact information; and the function of the valve operated by said valve handle.

Abstract: A flange with a shoulder piece that may be adjusted into different positions within a shoulder piece opening of a base piece. The shoulder piece includes a lip that catches a recessed portion of the base piece so that the shoulder piece is caught and held in position with the base piece. The base piece and shoulder piece may include complimentary indentations and protrusions so as to hold specific positions relative to one another. The base piece and shoulder piece may include base and shoulder screw holes so that the base and shoulder pieces may be screwed into a specific position.

Abstract: A threaded pipe flange and piping system utilizing the same. The threaded pipe flange includes a base portion having a predetermined shape and at least two openings dimensioned to accept at least two mounting bolts. A shoulder portion extends from, and is integral to, the base portion and includes at least two substantially flat gripping surfaces that allow the flange to be attached using an open end wrench, adjustable wrench or pipe wrench. A threaded opening extends through the base portion and the shoulder portion and is sized to mate with the threaded pipe to which the flange is to be attached. In operation, the pipe flange is attached to the predetermined threaded pipe by aligning the threaded opening with the predetermined threaded pipe, gripping the gripping surfaces of the shoulder portion, and rotating the pipe flange until the flange is tight.

Abstract: A hot water heating system, coupler and integrated flow system. The hot water heating system includes a first isolator valve, a flow control valve, a circulator and a second isolator valve. Each of these components is equipped with one portion of a connector on one side of the component and a mating portion of a connector on the other side. The integrated flow system includes a body into which is attached at least a circulator and a flow control valve.

Abstract: A hot water heating system, and kit for installing such a system, that utilizes male and female union connections for all main heating system components allows the system to be completely installed using only two ordinary wrenches. The system includes a first isolator valve, a flow control valve, a circulator and a second isolator valve. Each of these components is equipped with one male union type connection on one side of the component and one female union type connection on the other side. The system may be an installed system or may entail a kit of parts for installation.

Abstract: A sweat flange, piping system utilizing the same, and method of installing a circulator to a copper pipe. The sweat flange includes a base portion having a predetermined shape and at least two bolt openings dimensioned to accept at least two mounting bolts. A shoulder portion extends from the base portion and includes a substantially circular pipe opening that extends through the base portion and the shoulder portion. The pipe opening includes a first portion dimensioned to accept the pipe and a second portion of decreased diameter in order to limit the travel of the pipe through the opening. The sweat flange is attached to the pipe by inserting the pipe into the pipe opening of the flange and soldering the two together using art recognized soldering techniques. The piping system includes at least one pipe, a sweat, a pair of mounting bolts and a circulator or other pump.

The threaded pipe flange includes a base portion having a predetermined shape and at least two openings dimensioned to accept at least two mounting bolts. A shoulder portion extends from, and is integral to, the base portion and includes at least two substantially flat gripping surfaces that allow the flange to be attached using an open end wrench, adjustable wrench or pipe wrench. A threaded opening extends through the base portion and the shoulder portion and is sized to mate with the threaded pipe to which the flange is to be attached. In operation, the pipe flange is attached to the predetermined threaded pipe by aligning the threaded opening with the predetermined threaded pipe, gripping the gripping surfaces of the shoulder portion, and rotating the pipe flange until the flange is tight.

Abstract: A flange tightening tool for use in securing a flange to a pipe. The tool has a base plate, a tightening hexagonal shoulder, two attachment openings, two quick release disconnect mechanisms and a rotating handle perpendicular to the tightening base plate. The hexagonal shoulder enables the tool to be used with a companion light weight wrench. The tool can also be used with an open end wrench or an adjustable wrench. A rotatable handle is attached to the hexagonal shoulder such that said handle is perpendicular to the face of a flange that is to be tightened and can be used to hold the tool against the flange. When the quick release disconnect mechanisms are depressed about the pivot pin the quick release disconnect mechanism detracts from the mounting members releasing the mounting member separating the base plate and the flange. The tool prevents over tightening since the flange cannot be tightened past the point where the pipe contacts the base plate.
