Abstract: A valve system having a valve position indicator is disclosed. The valve position indicator allows for viewing of the valve position from one or more viewing locations. In one example, the valve position indicator includes a side valve open/close indicator and a top valve open/close indicator on a valve assembly. An indicator locking mechanism securely locks the valve position indicator in alignment with a position of a control valve.

Abstract: The invention is directed to an indicator (22) of the opening and/or closing status of a device controlling the flow of a fluid, such as a tap or a pressure reducer for compressed gas, comprising a sleeve-shaped support (24) to rotatably engage with a protruding portion (18) of a body of the device and from which an actuating spindle (20) extends along a longitudinal axis of said device; an indicator sleeve (26) axially sliding along the support (24); a rotor (28) to be fixed to the spindle (20) and comprising at its periphery a least one track (32) with a curved profile; and at least one track follower (30) extending radially from the indicator sleeve (26) through a longitudinal slot (242) in the support (24) and engaging with the at least one track (32).

Abstract: The invention is directed to a valve for gas under pressure, for example at temperatures below ?100° C., comprising a body with a gas inlet, a gas outlet and a passage connecting the inlet with the outlet; a shut-off device for closing the gas passage; a spindle designed for operating the shut-off device; and at least one gasket between the spindle and the body. The valve further comprises at least one cavity around the spindle for accumulating particles separated from the at least one gasket while operating the spindle and the shut-off device, for example at temperatures below ?100° C.
