Ball valves are probably the most common type of shut off valve. They are generally used when the shut off needs to happen quickly in an emergency situation or to allow maintenance of the system. It can be opened and closed completely with the help of a lever by a quarter-turn. When the internal ball of the valve is aligned with the pipe, it means that the valve is in the open position. The open position allows flow of the liquid or gas. With a rotation of the ball to 90 degrees, the valve will be closed and blocks the flow of the medium. Ball valves are usually sealed with a rubber or plastic fitting either side of the ball component. This eliminates leaks when the valve is in the closed position.
Another common usage of ball valves are Pneumatic or Actuator Ball valves. These valves integrate into systems to moderate valve opening and closure. They are often fitted with gauge monitors or flow meters to measure flow. Actuated valves are commonly used within industrial processes, manufacturing factories, chemical handling, food and beverage facilities, mining operations, power plants and energy sector use such as refineries. They are also frequently used in wastewater handling, municipal treatment facilities, clean water production, aquariums, aquatics and animal care, chemical synthesis, metals and plating operations.
Currie & Warner manufactures many components for these type of valves. They require high precision components with high surface finishes. Commonly the housing of the valve is made from a precision casting which is machined. Currie & Warner's contribution is the turned components which are assembled inside the valves. Below you can see some of the ball valve components we supply.
