A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

A valve has a closing member that can be brought from a closed position into an open position by a rotational movement about an axis of rotation transverse to a through-flow direction. A shaft is connected to the closing member and comprises a shaft end. A valve housing has an adjusting device, which has an adjusting device housing and comprises a receptacle in which the shaft end can be received. In order to be able to fix the valve in a switching position, a shaft portion comprises a passage that can be made congruent with two housing-side openings. The passage and the openings can be penetrated by a securing body, and the connection between the shaft and the shaft portion is secured against release when the passage and the openings are congruent.

The present disclosure relates to valve lockout systems, including valve lockout systems for use with an actuator and butterfly valves. The lockout system allows controlled access to operation of the valve, either to prevent intentional or unintentional operation of the valve. Thus, the lockout system prevents the unauthorized opening or closing of the valve. The lockout system includes a lockout plate in which a lockout bar is positioned. The lockout bar includes a surface containing a recess. Depending upon the location of the recess the valve shaft can be opened or closed.

The present invention is an improved fluid valve control device which attaches to a pre-existing and pre-installed hex head valve. The valve control device has at least one lever which can be used to turn the valve on or off. This device can be attached to a manifold assembly that has a valve which typically requires a tool to control so that it eliminates the need for a separate tool being used to turn the valve on or off after installation at relatively low cost.

An adapter cap for a fire hydrant including a hydrant actuation nut by means of which the hydrant is opened and closed by rotating the hydrant actuation nut, where the adapter cap includes a cap housing having connection means for connecting the adapter cap to the hydrant actuation nut, the cap housing having a cap actuation nut by which the adapter cap may be engaged and the cap housing including a skirt part arranged to encircle at least a part of the connection means, wherein a connection means centre axis of the connection means and a cap actuation nut centre axis of the cap actuation nut are arranged coaxially, wherein the connection means and the cap actuation nut are made from metal, and wherein at least a part of the skirt part is made from a polymer material, the adapter cap further includes at least one sensor arranged in the cap housing-(4), wherein the at least one sensor is arranged to detect at least one operational parameter of the hydrant , and wireless communication means arranged in the cap housing for communicating the at least one operational parameter wirelessly to an external data system .

A clamp arrangement for retaining a flexible tube (18) during operation of a roller pump (10) for pumping fluid, the clamp arrangement comprising a pair of rotatable bobbins (24A, 24B, 26A, 26B) mounted adjacent to each other. Each bobbin (24A, 24B, 26A, 26B) has a tapered groove (30), formed partially around a cylindrical surface of the bobbin (24A, 24B, 26A, 26B), and counter rotation of the bobbins (24A, 24B, 26A, 26B) clamps the tube 18 between the bobbins (24A, 24B, 26A, 26B) in the tapered grooves (30). The clamp arrangement allows tubes of different shapes and diameters to be securely held without overly deforming the tube.
