Ball

A sanitary Ball valve houses a sphere, or ball, with a central port that allows or restricts flow. As the valve handle is turned and the ball is rotated, the valve opens and medium passes through. In the fully open position, the valve provides unrestricted flow. When closed, flow is completely restricted. A locking handle keeps the ball in place.

Sanitary Ball valves require a one-quarter turn to go from the fully open to fully closed. This quick opening and closing makes the Ball valve a valuable tool where quickly isolating sections of the line is important. While Ball valves are generally used in the fully open or fully closed positions, the handle can be turned to semi-opened or semi-closed to control flow.

The most common type is the Full Port Ball valve. The sphere is oversized, with the port in the sphere being equal in size to the inside diameter of the tube to which the valve is mounted. This allows for unrestricted flow when the valve is fully opened.

At James Duva, Inc., our sanitary Ball valves are available in three-piece construction. The three-piece Ball valve is made up of two end caps and one body. The tri-clamp (tri-clover) end caps are where the connection to the line is made. A three-piece construction is ideal for processes that put heavy demands on the valve. To replace seats and seals, the three-piece valve can be easily disassembled, serviced and reassembled.

Sanitary Ball valves are manufactured for use in applications that require sterile or hygienic processing. Commonly used in dairy, food and beverage, pharmaceutical, medical, and chemical applications, all valve contact surfaces are polished to prevent impurities from settling and corrupting your medium. Ball valves are not recommended for flow control due to the potential for excessive wear.
