Abstract: A method of sealing a metal retainer to a metal valve body that includes the steps of applying a soldering paste in a predetermined amount to the threads of a threaded retainer and threading the retainer into the threads of a threaded opening in the valve. The retainer is heated to a temperature sufficient to liquefy and disperse the soldering paste into spaces between the threads of the retainer and the threads of the opening in the valve to thereby achieve an adhesive seal.

Abstract: A pinch clamp removal tool that includes a tool body having a slot extending partially across a top portion of the tool body and adapted for receiving a nub extending radially-outwardly from a pinch clamp to be removed from a pipe and a stop positioned at an end of the slot for engaging the nub when the nub is positioned in the slot. The tool body is adapted for being rotated to impart a twist to the pinch clamp nub sufficient to break the nub in order to loosen the pinch clamp and permit removal of the clamp from the pipe.

Abstract: A push-to-connect fitting removal tool that includes first and second handles pivotally-connected for being grasped and manually moved towards and away from each other, a first guide bar connected to both the first and second handles, and a second guide bar connected to both the first and second handles and cooperating with the first guide bar for converting pivotal movement of the first and second handles into non-pivoting, translation motion of the first and second guide bars. A push fitting jaw is attached to the first guide bar and a pipe jaw is attached to the second guide bar for being moved towards and away from each other as the first and second handles are moved towards and away from each other. The push fitting jaw is adapted for at least partially encircling the push fitting and the pipe jaw adapted for at least partially encircling the pipe.

Abstract: A backflow preventer that includes a housing having an inlet and an outlet adapted to be mounted in a liquid flow configuration in a liquid supply circuit. An upstream check disc assembly is positioned in the housing downstream of the inlet, and includes an upstream check plate supporting a downstream diaphragm. An upstream check disc is positioned downstream of the diaphragm and integrally formed with an upstream stem mounted in an aperture in a central hub formed in the check plate for movement between an normally open, flow position and a closed position preventing backflow of liquid through the inlet. A downstream check disc assembly is positioned in the housing downstream from the upstream check disc assembly. A vent discharges liquid to atmosphere upstream of the downstream check disc assembly.

Abstract: A spill-resistant vacuum breaker valve that includes a check assembly positioned in a valve body and is movable between an open position for allowing water to flow into the valve body through the water inlet and out of the valve body through the water outlet, and a closed position for preventing water from flowing out of the valve body through the water outlet. The check assembly cooperates with a float assembly movable by movement of the check assembly between an open position allowing air to enter the valve body through the air inlet and a closed position sealing the valve body against flow of air into the valve body through the air inlet. The float assembly is adapted to pivot sufficiently to level the float and seal against ejection of water from the valve in the event of non-axial movement of the check assembly in the valve body.

Abstract: A crimping head for use with an impact wrench to crimp fittings onto a structure carrying the fitting, that includes a universal adaptor having a head, and a socket positioned in the head sized and shaped to receive a standard anvil of an impact wrench without further connection between the impact wrench and the crimping head. A locking assembly is provided for cooperating with the universal adaptor head for locking the anvil into the socket, and a transmission is attached to the universal adaptor for being driven by the universal adaptor and for converting rotational movement of the anvil into selective rearward and forward movement. A jaw assembly is attached to the transmission and adapted to close into a crimping position and open into a release position responsive to the rearward and forward movement of the transmission.

Abstract: A ball valve including a valve body having a valve chamber, a ball member positioned in the valve chamber and defining first and second internal passages in fluid communication, and first and second seat rings, the first seat ring allowing fluid to flow past and through the second passage when the ball valve is in a life-sustaining flow operating position.

Abstract: An improvement for a backflow release valve of the type used for a backflow event in a supply line is provided. The improvement includes an air-liquid separator in fluid communication with the release valve and the supply line for reducing the amount of air entrained within a liquid solution entering the release valve, thereby reducing the total volume of liquid solution entering the release valve and minimizing the entrainment of water into air breaking a vacuum condition in the supply line.

Abstract: A valve handle assembly for a valve having an outwardly extending rotatable stem for opening and closing the valve by rotation of the stem includes a stop plate for engaging the stem, a handle for rotating the stem by engaging and rotating the stop plate, and a cup washer for engaging the handle and retaining the stop plate and handle on the stem upon placing a nut on the stem and tightening of the nut. The handle has an internal lip for retaining the handle and the cup washer has a raised flange for engaging the lip to retain the handle upon tightening of the nut.

Abstract: The present invention provides a valve actuator for a valve that includes a cylindrical body that is thermally nonconductive and configured to engage a valve stem. A cylindrical adjuster is positioned coaxially with the body. A shaft extends through the adjuster and the adjuster is axially movable between a first position and a second position such that when the adjuster is in the first position a first engaging means engages a second engaging means thereby fixing the position of the adjuster relative to the body. When the adjuster is in the second position the adjuster is radially movable relative to the body. A spring is aligned with the shaft and configured to bias the adjuster toward the first position such that the first engaging means engages the second engaging means thereby fixing the position of the adjuster relative to the body.
