Abstract:
A method of dissipating heat from a steam pressure regulator, the steam pressure regulator including a valve body defining an internal flow passage between a first port and a second port, a valve movable between a first position substantially preventing fluid communication through the internal flow passage and a second position permitting generally unrestricted fluid communication through the internal flow passage, and an actuator including an actuator body defining a chamber, a movable actuator wall dividing the chamber into first and second chamber spaces, and a shaft coupling the movable actuator wall to the valve, the method comprising:coupling an intermediate body between the valve body and the actuator body, the intermediate body being adapted for cooperative engagement with a fin arrangement; engaging the fin arrangement with the intermediate body; and dissipating heat from the fin arrangement to the ambient conditions around the fin arrangement that would otherwise be conducted from the valve body to the actuator via the intermediate body.
