LOCK BALL

615 077 79 LOCK BALL Functioning as a straightforward on/off control, this ball valve regulates the flow in low-pressure systems. It is commonly found in the water flushing circuit to control the supply to the drifter, or in pneumatic lines for various control functions. Its simple quarter-turn operation allows for quick isolation of a line, which is essential for both operational adjustments and maintenance procedures.

A properly functioning ball valve is crucial for the reliability of the system it serves. If the valve fails to close completely, it can lead to a constant, wasteful leak of air or water. A more critical failure is a restriction in flow when open, which could starve the drill bit of flushing water, leading to poor cuttings removal and potential jamming of the drill string in the hole.

Common signs of failure include leaks from the valve body or handle, or difficulty in turning the handle. If the valve no longer provides a tight seal when closed, it should be replaced. Always depressurize the line completely before attempting to unscrew the old valve.
