Abstract: The valve component comprises a valve member movable between an open position and a closed position. The valve component comprises a valve control mechanism including a drive member that moves the valve member. The drive member rotates the valve member between the open position and an intermediate position and linearly moves the valve member between the intermediate position and the closed position. The valve control mechanism includes a cam to drive the drive member. The cam includes a cam slot to engage the drive member. The cam slot includes a recess to receive the drive member in the closed position of the valve member so that the recess locates the drive member to resist or prevent linear movement of the valve member away from the valve closed position towards the valve intermediate position.

Abstract: A fluid conduit interlock comprises at least one retention member for engaging a fluid conduit, the or each retention member configured to be movable between a retention position for retaining the fluid conduit and a release position for releasing the fluid conduit, a valve member configured to be movable between a valve open position for opening a hollow bore and a valve closed position for closing the hollow bore, and an interlock mechanism configured to operably link the movement of the or each retention member and the movement of the valve member so that the or each retention member in the release position locks the valve member in the valve closed position and so that the valve member in the valve open position locks the or each retention member in the retention position.

Abstract: A valve component for a valve, the valve comprises a valve housing defining a hollow bore along which flowable material may flow. The valve component comprises a valve member movable between a valve open position for the valve member to open the hollow bore and a valve closed position for the valve member to close the hollow bore, and a valve control mechanism including a drive member configured to be operable to move the valve member between the valve open position and the valve closed position, the drive member operable to rotate the valve member between the valve open position and a valve intermediate position and to linearly move the valve member between the valve intermediate position and the valve closed position.

Abstract: A flange assembly includes a flange for connection to a hose or pipe, the flange defining a contact face for engagement with a contact face of an opposed flange. The flange assembly also includes at least three clamps spaced circumferentially around the contact face. Each clamp includes a clamp body pivotably secured to the flange and a clamp member mounted on the clamp body, which is movable between a first, retracted position and a second, clamping position. A clamp face of the clamp member faces the contact face of the flange. The clamp member is movable relative to the clamp body to adjust the position of the clamp face relative to the contact face of the flange and adjust a clamping force created between the clamp face and the contact face of the flange to retain an opposing flange in face-to-face engagement with the contact face of the flange.
