An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.

A first tubular and a second tubular define a fluid passage. A feather is positioned within the first tubular. The feather is configured to axially translate towards the second tubular and pivot towards a center of the first tubular. The feather includes a hinge on a pivoting end. A first end of a spring is coupled to the feather and a second end of the spring is coupled to the first tubular. The spring is loaded to actuate a movement of the feather between an open position and a closed position. A trigger is positioned between the first tubular and the second tubular to provide an interference with the feather. The interference retains the feather in the open position when the first tubular and second tubular are coupled.

Pallet racking systems are designed to quickly freeze items using thermal transfer by moving air through palletized products. Air is pulled through the palletized product to a negative air plenum behind the pallet rack. Back panels of the pallet racks provide variable-height airflow by use of louvers which are individually pressed open by the palletized product to accommodate differing product heights. The panels allow more efficient system operation with any number of rack positions filled.

A riser for a surface irrigation system, the riser having a housing and an outlet valve. The 5 housing has an open upper portion and an outlet defining an orifice through which irrigation fluid is to be discharged. The valve includes an upper closure, a valve member, and an actuating lever. The upper closure is securable to the riser for sealing the open upper portion. The valve member is coupled to the closure and mountable within a flow path of the fluid, the valve member operable for opening and closing the valve, and configured to 10 seat against a valve seat of the housing, and on an upstream side of the orifice, whereby the pressure of fluid within the valve urges the valve member against the seat when the valve is closed. The pivotable actuating lever having one end extending through the orifice and coupled to the valve member, an intermediate fulcrum, and an operable end for operating the valve member to open and close the valve.

A serviceable valve carousel system may include a valve carousel housing having a first port adapter receiver, a valve service port, and a second port adapter receiver. A rotatable valve carousel may be disposed within the valve carousel housing. The rotatable valve carousel may include a valve lumen and a removable valve cap. A first port adapter may be removably attached to the first port adapter receiver and a second port adapter may removably attached to the second port adapter receiver. The first port adapter and the second port adapter may be of a type or kind needed to facilitate connectivity. The rotatable valve carousel may be rotatable between a first state that allows fluid communication between the first port adapter and the second port adapter through a check valve and a second state that allows the worn check valve to be removed and replaced via the valve service port.

A valve housing for an exhaust-gas valve includes a first housing half-shell and a second housing half-shell, wherein the first housing half-shell and the second housing half-shell complement each other to form the valve housing. A first valve seat for a valve flap assembly and a swivel bearing mount to swivel mount the valve flap assembly are formed exclusively on the first housing half-shell. Furthermore, an exhaust-gas valve having such a valve housing and an exhaust system having such an exhaust-gas valve are presented. A vehicle having such an exhaust system is also presented. In addition, a method of manufacturing an exhaust-gas valve is explained.
