BREAK-AWAY CHECK VALVE
A break-away check valve is provided. The check valve may be configured between two passageways and may regulate the flow of liquid between the passageways. The check valve may include an actuation assembly that may actuate the check valve upon the system becoming dislodged or otherwise dislocated from at least one of the passageways.
Automatic shutoff valve for breakaway wet barrel fire hydrant
An automatic shutoff valve for breakaway wet barrel fire hydrant is disclosed. In general, one aspect disclosed features an apparatus comprising: a valve housing comprising a valve body, a flange, and a valve seat; a valve pedal configured to engage the valve seat and prevent fluid flow through the valve seat in a closed position, and to permit fluid flow through the valve seat in an open position; a lockout tab disposed within the valve body, wherein the lockout tab maintains the valve pedal in the open position; a lockout bar disposed distally from the valve body; and an activation rod mechanically coupled to the lockout bar and configured to keep the valve pedal engaged with the lockout tab.
Low water hammer break check valve
A valve closure device for a check valve can include a first valve member configured to rotate from an open position to a closed position; a second valve member configured to rotate from an open position of the second valve member to a closed position of the second valve member; and a hydraulic dampener coupled to each of the first valve member and the second valve member in each of the open position and the closed position of each of the first valve member and the second valve member, the hydraulic dampener configured to resist rotation of the first valve member towards the closed position of the first valve member and the second valve member towards the closed position of the second valve member.
Break-away check valve
A break-away check valve is provided. The check valve may be configured between two passageways and may regulate the flow of liquid between the passageways. The check valve may include an actuation assembly that may actuate the check valve upon the system becoming dislodged or otherwise dislocated from at least one of the passageways.
Hydrant enclosure with integral faucet
Provided is an enclosure with an integrated hydrant. The enclosure includes a fluid flow conduit that transfers fluid from a fluid supply tube to a fluid outlet, which may be associated with the backflow preventer. The enclosure has a conduit that carries water from the fluid supply tube to the backflow preventer. Thus, a lower profile, lighter, and more aesthetically pleasing enclosure is provided.
Adjustable underground utility boxes with shortening prevention sleeves
The present disclosure provides shortening prevention sleeves for adjustable underground utility boxes, underground utility boxes including such sleeves, and methods of preventing shortening of underground utility boxes with such sleeves. A sleeve comprises a substantially rigid elongate tube that defines an internal cavity. The tube is configured to allow a stem portion of an adjustable underground utility box to extend fully therethrough via the internal cavity. The sleeve also comprises an opening that extends along the length of the tube and provides a passageway into the internal cavity. The tube is configured to allow the stem portion of the box to pass through the opening and into the internal cavity. The sleeve is configured to extend over and along the stem portion and between enlarged top and bottom portions of the box to prevent the stem portion, and thereby the box as a whole, from shortening.
Break-away check valve
A break-away check valve is disclosed. The check valve may be configured between two passageways and may regulate the flow of liquid between the passageways. The check valve may include an actuation assembly that may actuate the check valve upon the system becoming dislodged or otherwise dislocated from at least one of the passageways.
Auxiliary valve for hydrant
A valve assembly for a hydrant can include a main valve defining a bore; and an auxiliary valve assembled to and extending through the bore of the main valve, the auxiliary valve defining a fluid channel through the auxiliary valve, the auxiliary valve including: an upper auxiliary valve shaft; a lower auxiliary valve shaft, the upper auxiliary valve shaft movable in a vertical direction with respect to the lower auxiliary valve shaft, a position of the lower auxiliary valve shaft restrained with respect to a position of the upper auxiliary valve shaft within a predetermined movement range; and a sealing element preventing fluid flow through the fluid channel.
Hydrant bayonet thrust nut and hydrant having the same
A threadless bayonet thrust nut assembly for a hydrant, a bayonet thrust nut, and a hydrant having the same, the assembly including the bayonet thrust nut with locking features extending radially therefrom, a hydrant bonnet having retainer lugs disposed around a top opening and corresponding to the locking features, and a lock plate having downwardly extending bayonet extensions, where the locking features are configured to pass through spaces delimited by the retainer lugs when the thrust nut is maneuvered through the opening into the bonnet, where the thrust nut is rotatable between an open position in which the locking features are aligned with the spaces and a closed position in which the locking features are aligned with the retainer lugs, where the bayonet extends of the lock plate are insertable into the spaces when the thrust nut is in the closed position, and where the thrust nut in the closed position is driven against an underlying operating nut disposed with in the bonnet so as to threadlessly secure the operating nut within the hydrant.
