Abstract

A valve assembly for use in a piping system includes a valve having an inlet and outlet arranged for connection to the piping system, and further includes a valve body, a control element disposed in a flow passage, and a shiftable valve stem operatively coupled to the control element. Valve packing is disposed about the valve stem and is secured by a retainer assembly. An adapter plate is provided and is attached to the valve body by a plurality of gland bolts, with the adapter plate and the gland bolts cooperating to secure the retainer assembly. An actuator bracket is provided and includes a first portion and a second portion, with the first portion secured to the adapter plate by a plurality of fasteners, and an actuator is secured to the second portion of the actuator bracket by a plurality of fasteners, with the actuator having a control rod operatively coupled to the valve stem.

First claim

What is claimed:

1. A method of servicing a valve assembly in a piping system, the method comprising:
providing a valve having an inlet and outlet in flow communication with the piping system, the valve further including a valve body, a control element disposed in a flow passage, a shiftable valve stem operatively coupled to the control element, and valve packing disposed about the valve stem and secured by a retainer assembly and a plurality of gland bolts;
providing at least a portion of the valve body generally adjacent the retainer assembly with a plurality of adapter apertures;
providing an actuator bracket having a first portion and a second portion that extends generally perpendicular to the first portion of the actuator bracket, and securing the first portion to the adapter apertures by a plurality of fasteners;
providing an actuator secured to the second portion of the actuator bracket by a plurality of fasteners, the actuator having a control rod operatively coupled to the valve stem, the control rod having a longitudinal axis that is generally perpendicular to a longitudinal axis of the valve stem; and
removing the actuator, including removing the plurality of fasteners securing the first portion of the actuator bracket to the adapter apertures, while maintaining a process fluid in the piping system.

2. The method of claim 1 , arranging the plurality of adapter apertures in a first pattern and a second pattern, the first pattern arranged to support the first portion of the actuator bracket in a first position, the second pattern arranged to support the first portion of the actuator bracket in a second position, and selecting the first pattern or the second pattern when initially attaching the actuator bracket to the valve body.

3. The method of claim 1 , including providing the first portion of the actuator bracket with a cutout sized to provide an access opening to at least one of the gland bolts.

4. The method of claim 1 , wherein the control rod of the actuator is operatively coupled to the valve stem through a clevis and pin.

5. A valve assembly for use in a piping system and comprising:
a valve having an inlet and outlet arranged for connection to the piping system, the valve further including a valve body, a control element disposed in a flow passage, and a shiftable valve stem operatively coupled to the control element;
valve packing disposed about the valve stem and secured by a retainer assembly;
an adapter plate overlying the retainer assembly and attached to the valve body by a plurality of gland bolts, the adapter plate and the gland bolts cooperating to secure the retainer assembly;
an actuator bracket having a first portion and a second portion, the first portion secured to the adapter plate by a plurality of fasteners;
an actuator secured to the second portion of the actuator bracket by a plurality of fasteners, the actuator having a control rod operatively coupled to the valve stem; and
wherein the adapter plate includes a plurality of actuator bracket mounting apertures arranged in a first pattern and a second pattern, the first and second patterns arranged to permit the actuator bracket to be mounted on the adapter plate in either a first position or a second position, thereby permitting the actuator to be mounted in either a first position or a second position relative to the valve body; and
wherein the adapter plate and the actuator bracket cooperate to permit the actuator bracket to be dismounted from and remounted to the valve body without disturbing the valve packing.

6. The valve assembly of claim 5 , wherein the first portion of the actuator bracket includes a cutout sized to provide an access opening to at least one of the gland bolts.

7. The valve assembly of claim 6 , wherein the cutout is sized and positioned to provide the access opening to the at least one of the gland bolts when the actuator bracket is attached to the valve body and the actuator is attached to the actuator bracket.

8. The valve assembly of claim 5 , wherein the gland bolts engage only the adapter plate and the valve body.

9. The valve assembly of claim 5 , wherein a longitudinal axis of the control rod is generally perpendicular to a longitudinal axis of the valve stem.

10. The valve assembly of claim 5 , wherein the first portion of the actuator bracket is generally perpendicular to the second portion of the actuator bracket.

11. The valve assembly of claim 5 , wherein the control rod of the actuator is operatively coupled to the valve stem through a clevis and pin.

12. An adaptive assembly for use with a valve and actuator assembly, the valve and actuator assembly including a valve, a valve stem surrounded by valve packing, and an actuator, the adaptive assembly comprising:
an adapter plate securable to a valve body of the valve and sized to permit passage of the valve stem through the adapter plate, the adapter plate arranged to receive a plurality of gland bolts attachable to the valve body;
the adapter plate overlying and securing a retainer plate to the valve body, the retainer plate operatively coupled to and applying a compressive force to the valve packing;
an actuator bracket having a first portion and a second portion that extends generally perpendicular to the first portion of the actuator bracket, the first portion secured to the adapter plate by a plurality of fasteners;
the second portion of the actuator bracket arranged to receive an actuator using a plurality fasteners to permit a control rod of the actuator to be operatively coupled to the valve stem, the control rod having a longitudinal axis that is generally perpendicular to a longitudinal axis of the valve stem; and
wherein the adaptive assembly is arranged to permit the actuator bracket to be dismounted from and remounted to the valve body without disturbing the valve packing.

13. The adaptive assembly of claim 12 , wherein the adapter plate includes a plurality of actuator bracket mounting apertures arranged in a first pattern and a second pattern, the first and second patterns arranged on the adapter plate to permit the actuator bracket to be mounted to the adapter plate in either a first position or a second position, thereby permitting the actuator to be mounted in either a first position or a second position relative to the valve body.

14. The adaptive assembly of claim 13 , wherein the first portion of the actuator bracket includes a cutout sized to provide an access opening to at least one of the gland bolts.

15. The valve assembly of claim 12 , wherein the control rod of the actuator is operatively coupled to the valve stem through a clevis and pin.
