Abstract
An actuation system for a valve assembly is provided, the actuation system includes an actuation unit arranged to engage with an operating member of a valve to drive rotation of the operating member; and a remote actuation device arranged at a distance from the actuation unit and coupled to the actuation unit by an actuation cable, the actuation cable being operable to engage the actuation unit to drive rotation of the operating member; wherein the actuation system further includes an environmentally sensitive actuator arranged to operate the actuation cable; and wherein the remote actuation device includes a manual input element arranged to operate the actuation cable.
Claims25
An actuation system for a valve assembly, the actuation system comprising:
- an actuation unit arranged to engage with an operating member of a valve to drive rotation of the operating member;
- and
- a remote actuation device arranged at a distance from the actuation unit and coupled to the actuation unit by an actuation cable, the actuation cable being operable to engage the actuation unit to drive rotation of the operating member;
- wherein the actuation system further includes an environmentally sensitive actuator arranged to operate the actuation cable;
- and
- wherein the remote actuation device includes a manual input element designed to receive a specific manual input, the manual input element arranged to operate the actuation cable in response to the specific manual input.

An actuation system for a valve assembly, the actuation system comprising:
- an actuation unit arranged to engage with an operating member of a valve to drive rotation of the operating member;
- and
- a remote actuation device arranged at a distance from the actuation unit and coupled to the actuation unit by an actuation cable or linkage, the actuation cable being operable to engage the actuation unit to drive rotation of the operating member;
- wherein the remote actuation device includes a manual input element and a remote trigger mechanism arranged to operate the actuation cable or linkage;
- wherein the manual input element is a push button and the remote trigger mechanism is arranged to convert an axial movement of the push button into a rotational movement that operates the actuation cable or linkage.
An actuation system for a valve assembly, the actuation system comprising:
- an actuation unit arranged to engage with an operating member of a valve to drive rotation of the operating member;
- and
- a remote actuation device arranged at a distance from the actuation unit and coupled to the actuation unit by an actuation cable, the actuation cable being operable to engage the actuation unit to drive rotation of the operating member;
- wherein the actuation system further includes an environmentally sensitive actuator arranged to operate the actuation cable;
- wherein the remote actuation device includes a manual input element arranged to operate the actuation cable;
- wherein the remote actuation device comprises at least one remote trigger member coupled to an end of the actuation cable;
- and
- wherein the at least one remote trigger member is arranged to be operated by the environmentally sensitive actuator and arranged to be operated by the manual input element.
