A sandwich ball valve is a type of valve used in industrial applications to control the flow of fluids through a piping system. The valve is called a sandwich valve because it is designed to fit between two flanges, with one flange serving as the inlet and the other as the outlet.

The sandwich ball valve consists of a body with a ball-shaped disc that rotates to open or close the valve. The ball is held in place by a stem that is attached to an actuator, which can be manually or electrically operated. When the actuator is engaged, the stem rotates the ball, allowing fluid to flow through the valve or stopping it.

One of the significant advantages of the sandwich ball valve is its ability to provide a tight seal when closed. The ball-shaped disc sits snugly against the valve seat, creating a seal that prevents fluid from leaking through the valve. When the valve is open, the ball rotates to allow fluid to flow through the valve with minimal resistance.

Another advantage of the sandwich ball valve is its high flow rate capacity. The valve design allows for a smooth flow of fluid through the valve, resulting in minimal pressure loss. This is particularly important in applications where maintaining high flow rates is critical.

The sandwich ball valve is available in various sizes and configurations to suit different piping systems' requirements. They are made from high-quality materials such as stainless steel, carbon steel, and brass, and are designed to withstand high-pressure and temperature.

The installation of the sandwich ball valve is straightforward and typically involves mounting the valve between two flanges on the piping system. The valve is secured in place using bolts and nuts, and piping is attached to the inlet and outlet ports.

In conclusion, the sandwich ball valve is a type of valve used in industrial applications to control the flow of fluids through a piping system. They provide a tight seal when closed, have a high flow rate capacity, and are available in various sizes and configurations to suit different piping systems' requirements. They are made from high-quality materials that can withstand high pressure and temperature and are easy to install.
