The Cam-Tite® ball valve is a quarter turn with a uniquely designed ball geometry that is optimized for tight shutoff and process isolation. The spherical surface around the port edge of the ball is machined away, forming a bevel that passes completely around the port opening. The resulting non-spherical ball mechanically compresses both upstream and downstream seats to effect a tight, dependable seal independent of line pressure.
The Cam-Tite® is unique from other floating ball valve designs since it does not rely on upstream pressure to force the ball into the seat to create a seal. Breakaway torque is also minimized with this valve, which is especially important when the valve remains in the closed position for long periods of time.
The top entry design employs a bolted bonnet which provides mechanical support for the valve stem using upper and lower stem seals. By using upper and lower stem seals, lateral loading is minimized maintaining near perfect alignment. This results in a low operating torque and long stem seal life without leakage. The top entry design feature allows for easy removal and replacement of all trim components utilizing one subassembly
