Abstract: A boiler loop system including a primary-secondary piping loop interface apparatus including a flow diversion device, and a drain valve, and a drain port in branches from a circumferential sidewall. In an embodiment, supply branch piping and return branch piping connect the primary-secondary piping loop interface apparatus to a boiler and provide attachment points for auxiliary plumbing equipment. In an embodiment, the boiler loop is integrated into the primary loop.

Abstract: The present invention is generally directed to an isolation valve unit including a valve body comprised of a metal, such as brass, and having at least two ports, at least one of the ports including an overmolded thermoplastic end surrounding and enclosing the port. In one embodiment, the thermoplastic end is composed of a polypropylene random (PP-R) material and is securely formed over the port by way of an over molding technique. The valve unit further includes a ball valve accommodated within the valve body and a handle for actuating the ball valve. The isolation valve unit is configured to control the flow of fluids in a plumbing system via actuation of the ball valve.

Abstract: A purge valve comprising a valve body having a first primary loop port, a second primary loop port, a first secondary loop port and a second secondary loop port is provided. The secondary loop ports are disposed at respective ends or a linear secondary loop portion of the valve body. A primary loop portion of the valve body is formed by a pair of closely spaced tees extending from the secondary loop portion. At least one main valve portion is disposed in a first one of the tees. A drain/venting valve portion extends from the main valve portion. A portion of the secondary loop portion between the tees is shared with the primary loop portion in which flow in a primary loop and a secondary loop are hydraulically separated. A second drain/venting valve portion may be provided in a second one of the tees.

Abstract: A fluid isolation valve having a valve body with a first fluid flow port, a second fluid flow port and a fluid drain port with a valve in the fluid drain port. The valve body also defines a fluid flow channel, a drain flow channel and a valve portion, wherein the valve portion is disposed in the valve body to be communicated with the first fluid flow port, the second fluid flow port and the fluid drain port. A flow diversion device is also provided and is disposed within the valve portion. The flow diversion device is configurable between a first configuration and a second configuration, such that when the flow diversion device is in the first configuration the first fluid flow port is communicated with the second fluid flow port. Consequently, when the flow diversion device is in the second configuration the first fluid flow port is communicated with the fluid drain port. The fluid flow can be decrease or stop by use of the valve within the fluid drain port.
