BALL VALVE COUPLING

摘要

This invention relates to an environmental coupling that reduces spillage to less than 1 ml. One ball valve (22') includes flat surfaces (102') on the ball and a retainer (104') with "flats" (106') that correspond to the "flats" on the ball valve. This feature keeps the ball valve (22') on centerline and allows valve actuation without damage to either ball valve. The coupling also provides other numerous safeguards against spillage. For instance, the handle design prohibits wrong sequencing of opening and closing the ball valves.
