Abstract
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.
Claims21
A valve assembly, comprising:
- 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;
- wherein the handle has a first opening and the valve housing has a second opening, wherein 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;
- wherein the valve actuator is a multi-turn actuator;
- wherein the open position of the multi-turn actuator includes rotational amounts from the closed position of 360 degrees and greater than 360 degrees.

A valve assembly, comprising:
- 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;
- wherein the handle has a first opening and the valve housing has a second opening, wherein 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;
- an indicator stem configured for slidable movement relative to the handle in response to movement of the handle;
- wherein the indicator stem has a third opening, wherein when the valve actuator is in the closed position the first opening aligns with the third opening to enable receipt of the lockout member to prevent movement of the valve actuator from the closed position to the open position.

A valve assembly, comprising:
- 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;
- wherein the handle has a first opening and the valve housing has a second opening, wherein 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, wherein the valve assembly can be locked out only when the valve actuator is in the closed position;
- wherein the first and second openings extend transverse to the actuation axis,
- wherein the handle is axially and rotatably movable within an opening in the valve housing, and wherein a central axis of the first opening axially aligns with a central axis of the second opening along the actuation axis when the valve actuator is in the closed position, and wherein when the valve actuator is in the open position the central axis of the first opening is axially above the central axis of the second opening along the actuation axis.
