Flange end ball valves are widely used in mining due to their ability to provide precise fluid control and tight shutoff in high-pressure mining environments with hydraulic valves.The floating ball mechanism allows the ball to move slightly under pressure, pressing against the downstream seat for a secure seal.
[pdf] Install the valve with proper positioning of the flow arrow. Support and align adjacent piping and the vale. Install lubricated flange bolts. Hands tighten, and then torque the bolts using the crossover flange bolt-tightening method to load the bolts evenly, and eliminate concentrated stresses.
[pdf] A drill pipe float valve, also recognized as a non-return valve, is a specialized valve installed in the bottom hole assembly (BHA) and its primary function is to serve as a check valve, permitting the downward flow of drilling mud through the drill string but preventing any unwanted fluid from flowing back up into the drill string.
