Abstract
A lower housing assembly for a valve actuator comprises a lower housing and an inventive latch subassembly. The lower housing includes valve stem and mounting post apertures that receive therethrough the valve stem and mounting post of a valve assembled with the lower housing assembly. The inventive latch subassembly comprises a rigid latch lever and a latch bias member. The rigid latch lever pivots between engaged and disengaged positions; the latch bias member biases the latch lever toward the engaged position. In the engaged position, the latch lever obstructs the mounting post aperture to prevent assembly of the lower housing with the valve, or engages a slot in the mounting post to prevent disassembly of the lower valve housing from the valve. In the disengaged position, the mounting post aperture is unobstructed by the latch lever, thereby permitting assembly and disassembly of the lower housing and the valve.
