INTRODUCTION
Ball valves are most widely used valves for flow control in fluid flow lines for wide range of temperature changes (-200°C to 500°C).Most of the outlet valves of chemical plant storage were installed with ball valves for sudden closing and opening purposes. For petroleum and chemical plants it is very convenient to operate with ball valves.
Ball valves are used in situations where tight shut-off is required. The type of seat can vary with the valve pressure rating and m ....etc

A ball valve (like the butterfly valve, one of a family of valves called quarter turn valves) is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle position lets you 'see' the valve's position.

Ball valves are durable and usually work to achieve perfect shutoff even after years of di ....etc

A patented new power machine concept has been designed and analyzed for production, and proof of principle subscale tests have been performed, with positive results. The machine design concept is applicable as a compressor, pump, motor, or engine. Simplicity of design based on spherical ball pistons enables a low moving part count, high power to weight ratio, elimination of valve train and water cooling systems, and perfect dynamic balance.The new design concept utilizes novel kinematic design to completely eliminate inertial loads that would c ....etc
