Abstract
A separable flange retainment system includes a first boss on the flange and a mating second boss on a valve body. The boss on the valve body has a threaded aperture for reception of a suitable fastener. A generally U shaped retainer device having an orifice in its bight portion straddles the bosses and is secured in position by the fastener. The retainer device precludes lateral and rotational movement between the flange and the body.
