A valve member closes in response to the impact to close off the flow of fluid to the hydrant.

Abstract: A check valve comprises a valve body defining a valve opening and a pair of valve elements mounted so as to be movable from a closed position in which they close the valve opening to prevent fluid flow through the opening to an open position in which they permit fluid flow through the opening. The valve further comprises a one piece bridge element having first and second end portions mounted to the valve housing on opposite sides of the valve opening and an intermediate portion extending between the end portions. The intermediate portion acts as a stop for the valve elements in their open position. A shaft mounting the valve elements for pivotal movement between their open and closed positions, is supported in the end portions of the bridge element. Fasteners for attaching the bridge element to the valve housing overlap the ends of the valve shaft thereby retaining it in the bridge element.

Abstract: A sanitary hydrant comprises an isolated reservoir that can be positioned below a freeze level at the location of installation. A piston within the isolated reservoir is operable to expel, during a downward stroke, stored fluid from the reservoir before actuating a valve that allows fluid to flow from a fluid supply source through the hydrant. On an upward stroke, the piston releases the valve and generates a negative pressure within the reservoir that draws fluid from within the hydrant into the reservoir.

Abstract: One or more techniques and/or systems are disclosed for a fluid inlet that mitigates uptake of undesired debris into fluid transport system. A fluid inlet can direct fluid toward one or more fluid inlets, and debris entrained in the fluid may bypass the fluid inlet(s). The fluid inlet can be used to mitigate uptake of debris into a fluid transport system, when placed in the path of fluid flow. A shape of the fluid inlet can be configured to direct fluid flow into the fluid inlet(s), while the shape allows debris entrained in the fluid to flow past the fluid inlet(s).
