Abstract
A sanitary valve includes a valve body having a straight-through cylindrical valve chamber terminating in flanges with a valve element support intersecting the valve chamber at a right angle. The valve element is cylindrically shaped with a hemispherical tip that is covered with an elastomeric material which includes a raised circular seal that extends around the circumference of the valve element and a raised U-shaped seal that extends over the tip. The circular seal always engages the supporting means in both the rotatable and sliding versions of the valve to preclude any environmental exposure of the valve chamber.
