Patent ID: 7828268

Claim:
A valve actuator for a valve, comprising; (a) a cylindrical body that is thermally nonconductive and has a first wall that defines a first space and a first engaging means formed on a first end of the body; (b) a cylindrical adjuster positioned coaxially with the body and having a second wall that defines a second space and a second engaging means formed on the adjuster for cooperative engagement with the first engaging means; (d) a shaft that extends from a valve stem through the second space within the adjuster, wherein the adjuster is retained on the shaft; (e) the adjuster being axially movable between a first position and a second position such that when the adjuster is in the first position the first engaging means engages the second engaging means thereby fixing the position of the adjuster relative to the body and when the adjuster is in the second position the adjuster is radially movable relative to the body; and (f) a spring aligned with the shaft biasing the adjuster toward the first position such that the first engaging means engages the second engaging means thereby fixing the position of the adjuster relative to the body.
