A fire hydrant includes an upper barrel, which further includes a body and at least one outlet. The body has a longitude, a longitudinal axis, a first portion, and a second portion, the first portion forming a first length of the longitude, the second portion forming a second length of the longitude, the first portion coupled to the second portion, the body having at least one wall defining an internal cavity. The first portion has a first dimension spanning the cavity perpendicular to the longitudinal axis between opposing points on the at least one wall. The second portion has a second dimension spanning the cavity perpendicular to the longitudinal axis between opposing points on the at least one wall. The first dimension is greater than the second dimension.
A spring return check valve that has a body forming a fluid flow path therethrough, a cover that closes an opening in the body and including a cavity therein facing the fluid flow path, a disc that rotates from a first position closing the fluid flow path and a second position fully opening the fluid flow path and a spring connected between the cover and the disc and including extensions integrally extending from each end of the spring to cause the spring to buckle into the cavity when the disc rotates to the second position.
A limit switch assembly, for a rising-stem valve having a stem with a diameter and a groove marking a desired stem position, includes an actuator arm having an inner end and an outer end. The inner end of the actuator arm forms a follower. A radius washer is mounted to the outer end of the actuator arm. An electrical switch has an operating lever and is mounted adjacent to the outer end of the actuating arm such that when the actuator arm is in an outward position the radius washer moves the operating lever, operating the electrical switch. When the actuator arm is in an inward position the radius washer does not move the operating lever and the electrical switch is not operated. A bias spring biases the actuating arm toward the inward position.

A limit switch for a rising-stem type valve which has a spring-loaded actuator arm with a bracket on one end which wraps around the valve stem. A follower or roller on the end of the bracket opposite the actuator arm rides on the rising stem of the valve, held in contact with the stem by the spring. When the stem has risen to a preselected position, usually the position in which the valve is fully open, the follower or roller engages a circumferential groove formed around the stem. This causes the spring to bias the actuator arm to move a tab at the opposite end of the actuator arm, and the tab operates a limit switch.

Breaker straps, preferably made of steel, include holes that line up with the holes in breaker rings, to keep the breaker rings in place on a fire hydrant. A collision kit includes breaker straps, the breaker rings, a coupling, and coupling pins.
A novel hose nozzle has a cup shaped capture nozzle housing with a curved shape similar to the mating O-ring. The cup shaped ends of the nozzle create a 45 degree angle. The novel shape of the ends of the nozzle traps the O-ring at the same radius of the O-ring. Rounding off the end of the nozzle permit the ends to have a radius equivalent to the O-ring. The O-ring is aligned with the nozzle, because there is no longer a round item trying to fit onto a flat surface. This design stabilizes the end of the nozzle, and keeps the nozzle from becoming crooked. The mating surfaces between the nozzle cup and the O-ring are the same. The O-ring mating surface has a complementary shape to the nozzle mating surface and the radius at the end of the nozzle preferably matches the radius of the O-ring.
A hydrostatic tank floor relief valve of a construction described herein provides for equalization of hydrostatic pressure of fluid in a storage tank with hydrostatic pressure of ground water surrounding the storage tank. A high efficiency grate located in a flow channel of the hydrostatic tank floor relief valve blocks debris from entering the storage tank during pressure equalization, yet does not reduce effective flow rates through a flow channel of a given diameter. The hydrostatic tank floor relief valve optionally includes an elastomeric seal surface and a stainless steel seat ring that reduce the likelihood of particulate matter disrupting valve operation, and provide a more reliable seal.

A cartridge seated plug valve includes a hollow body with an inlet, an outlet, and a cylindrical valve chamber. A C-shaped rotor with an elastomeric coating is rotatably held in the valve chamber by a valve cover and a base. A valve facing with an elastomeric gasket is held adjacent to the inlet, with a central aperture of the valve facing aligned with the inlet, and the elastomeric gasket held in compression about an inlet seal surface at a perimeter of the inlet, by facing channels in the cover and base. In a closed position, the rotor is oriented with the elastomeric coating of the plug segment sealing the central aperture. The valve is opened by rotating the main stem, changing an orientation of the rotary plug, and moving the plug segment away from the inlet.

A cushioned check valve includes a flow channel with an inlet, a check valve, and an outlet. Bypass channels connect the outlet, a cylinder containing a piston, and the inlet. The piston is biased toward a first end of the cylinder by a diaphragm and a hermetically sealed gas volume containing a compressible gas, blocking the bypass channels. When the fluid pressure in the outlet exceeds a nominal operating range, the piston moves toward a second end of the cylinder until the fluid pressure acting on the piston is equalized by the piston bias, and fluid flows through the bypass channel. Once the fluid pressure and piston bias are equalized, the piston returns to a position blocking the bypass channels.
An expanding disk gate valve assembly comprises two gate disks and an elastomeric disk. A first flange on a first gate disk mates to a second flange on a second gate disk forming an internal volume surrounding the elastomeric disk. An elastomeric sheath covers the mated disks with the first gate disk being radially offset from, and radially movable relative to, the second gate disk. A width of the gate disk assembly is less than a width between two valve seats when the gate disk assembly is in an open position. In a closed position, the first flange moves radially toward the second flange, compressing elastomeric disk, and causes the elastomeric disk to expand axially against the two gate disks, forcing them apart, and increasing the gate disk assembly width so that the gate disk assembly actively seals against the valve seats.

A drain valve slide and drain valve facing seal an elbow drain hole in a dry barrel fire hydrant when the main valve is closed. A first wedge on the main valve assembly engages the elbow when the main valve is opened and biases the drain valve slide and drain valve facing toward the elbow drain hole, creating a positive seal.
A hydrant main valve includes a main seal elastically deformable between a first state and a second state, such that a main valve assembly may be inserted into a main valve elbow without removable valve seats. A main valve assembly rotation lock engages a rotation block inside the elbow preventing rotation of the main valve assembly. A rotating operating stem extension moves a main valve bottom plate relative to a drain valve body, causing main valve seal elastic deformation.
A mud valve having a flange frame and yoke that are permanently connected to form a single unit without the aid of removable fasteners is described. Installation of the drain plug is facilitated by an arrangement of guide tabs on either side of the drain plug that are of different distances from the surface of the drain plug. This staggered arrangement allows the drain plug to be installed through a tilting and rotating of the drain plug that brings the tabs into alignment with guide rails on the yoke without necessitating the separation of the yoke from the flange frame. Similarly, the construction described allows the drain plug to be removed for repair or replacement in the field without disassembling the yoke and flange frame.
An actuator for a butterfly valve, having a gearbox, an actuator stem and a handle. The actuator stem is formed as a single piece, comprising a position indicator, seal disc, worm gear, and stem shaft with splines for fitting into the valve. The handle is also formed as a single piece, comprising the wheel or knob, shaft, and worm for operating the worm gear. By forming the gearbox as a single piece as well, the entire actuator can be made as three major pieces. Optionally, the gearbox can be formed with cylindrical fittings which press-fit over pins on the valve, replacing the conventional mounting bracket.
