RISING STEM BALL VALVE

Control Seal’s Non Contact Rising Stem ball valves are single seat non friction design, this valve was designed for frequent switching and fluctuating temperature services, The Control Seal design is also recommended for emergency shut down and blow down service, Control Seal has also developed a Non Contact rising stem ball valve for sand slurry design with a sand content of +/- 50%.

An important aspect of the life time of a valve is the sealing mechanism. Almost all valves, like standard Ball, Gate, Plug and butterfly valves have their sealing mechanism based upon shear force, friction and tearing. The Rising Stem Ball Valve sealing mechanism is based upon axial movement only. The sealing is not liable to friction or tearing. This friction free quarter turn mechanical energized sealing means no abrasion on the seal and, compared with other types of valves an exceptional long life time.
