Valve actuator assembly

A kit comprising:

• a valve body;
• an actuator assembly associated with the valve body, the actuator assembly comprising:
• a main body;
• a perimeter compressor disposed adjacent to the main body and slidable with respect to the main body between a retracted position and an extended position;
• an actuator shaft that extends through the main body and the perimeter compressor and that is slidable with respect to the main body and the perimeter compressor between an extended position and a retracted position, the actuator shaft comprising a proximal end and a distal end;
• an actuator operably coupled with the proximal end of the actuator shaft and operable to facilitate sliding of the actuator shaft between the extended position and the retracted position;
• and
• a sealing member comprising an inner portion and an outer portion that extends radially therefrom, the inner portion being releasably coupled with the distal end of the actuator shaft, wherein:
• sliding of the actuator between the retracted position and the extended position causes the sealing member to selectively form a fluid seal with the valve body;
• sliding of the perimeter compressor between the retracted position and the extended position causes selective formation of a perimeter seal with the valve body;
• and
• when the perimeter compressor is in the retracted position, the perimeter compressor is spaced from the valve body such that the perimeter compressor no longer imparts a downward force onto the sealing member.

A sealing member comprising:

• an inner portion;
• an outer portion that extends radially from the inner portion;
• a lower surface that extends between the inner portion and the outer portion and is configured to at least partially interface with a valve body to control fluid flow therebetween;
• an upper surface that extends between the inner portion and the outer portion and is spaced from the lower surface;
• a rail that is coupled with the inner portion at the upper surface and extends therefrom and is configured to be releasably coupled with an actuator shaft of an actuator assembly to facilitate coupling of the sealing member thereto;
• and
• at least one tab member that extends from the outer portion for selective grasping by a user.

An actuator assembly configured for attachment to a valve body, the actuator assembly comprising:

• a main body;
• a perimeter compressor disposed adjacent to the main body and slidable with respect to the main body between a retracted position and an extended position;
• an actuator shaft that extends through the main body and the perimeter compressor and that is slidable with respect to the main body and the perimeter compressor between an extended position and a retracted position, the actuator shaft comprising a proximal end and a distal end;
• an actuator operably coupled with the proximal end of the actuator shaft and operable to facilitate sliding of the actuator shaft between the extended position and the retracted position;
• and
• a sealing member comprising an inner portion and an outer portion that extends radially therefrom, the inner portion being releasably coupled with the distal end of the actuator shaft, wherein the sealing member is accessible through the main body to facilitate removal thereof while the actuator assembly is attached to the valve body.
