Abstract
A powered actuating assembly configured for mounting on a tubular valve body. The actuating assembly includes: (a) an actuator unit configured to impart torque to the valve stem; (b) an actuator mounting plate with a first surface supporting the actuator unit and a second surface configured to engage and resist movement relative to the valve body; and (c) securing links configured to extend around a valve body surface opposite the mounting plate and secure the mounting plate to the valve body.
Claims21
An actuating valve sub assembly comprising:
- (a) a tubular valve body housing a valve and a valve stem accessible from an exterior of the valve body;
- (b) a powered actuating assembly mounted on the valve body, the actuating assembly comprising:
- (i) an actuator unit configured to impart torque to the valve stem;
- (ii) an actuator mounting plate with a first surface supporting the actuator unit and a second surface configured to engage and resist movement relative to the valve body;
- and
- (iii) securing links configured to extend around a valve body surface opposite the mounting plate and secure the mounting plate to the valve body;
- (c) a plurality of actuator stems, wherein each actuator stem has a different size tool head, wherein the actuator unit imparts torque to one of the actuator stems which engages the valve stem.
A powered actuating assembly configured for mounting on a tubular valve body, wherein the valve body houses a valve and a valve stem accessible from an exterior of the valve body, the actuating assembly comprising:
- (a) an actuator unit configured to impart torque to the valve stem;
- (b) an actuator mounting plate with a first surface supporting the actuator unit and a second surface configured to engage and resist movement relative to the valve body, wherein the second surface has a curvature substantially corresponding to a curvature of an outer surface of the valve body;
- and
- (c) securing links configured to extend around a valve body surface opposite the mounting plate and secure the mounting plate to the valve body.
A method for actuating a valve sub assembly, the method comprising the steps of:
- (a) positioning a powered actuating assembly on a tubular valve body, wherein the valve body houses a valve and a valve stem accessible from an exterior of the valve body;
- (b) wherein the powered actuating assembly comprises:
- (i) an actuator unit configured to impart torque to the valve stem;
- (ii) an actuator mounting plate with a first surface supporting the actuator unit and a second surface configured to engage the valve body and resist torque applied to the valve stem, wherein the second surface has a curvature substantially corresponding to a curvature of an outer surface of the valve body;
- and
- (iii) securing links configured to extend around a valve body surface opposite the mounting plate and secure the mounting plate to the valve body;
- (c) tensioning the securing links on the valve body;
- and
- (d) applying toque to the valve stem with the actuator unit.
