A diaphragm valve is an elastic, tight-sealing valve that serves to control fluids, gasses, or slurries in a wide range of applications from water and wastewater treatment pharmaceuticals chemical processing. It comprises a flexible diaphragm generally made of rubber or elastomer which serves as the flow control element. This diaphragm splits the valve body into two parts and flow is controlled by moving the diaphragm up and down against a weir or saddle-shaped seat contained inside the valve. 

The seat is pressed against by the diaphragm to close off when the valve is closed, but lifts if the valve is open. This seal, with corrosive or abrasive material, is not imposable, and prevents contaminants from entering the flow path. The maintenance of diaphragm valves is easy, provides precise flow control, is appropriate for both on/off and throttling applications, and places them ideally for many fluid-handling systems.

The basic difference between a ball valve and a diaphragm valve lies in their design, mode of operation, and applications:

Design and Operation: A ball valve utilizes a rotative ball with a hole through its center to control flow; turning the handle turns the ball, opening or closing fluid passage. It's compared with the flexible diaphragm valve that makes use of the flexible diaphragm pressing against the seat or lifting away to control flow, providing for greater more exact control.

Ball valves are suitable for quick on/off services, and when turned 90 degrees, they pass full flow or shut off completely. The diaphragm valve gives better throttling and flow control and should, therefore, be used in applications where more precision is needed.

Suitability: Ball valves suit high pressures and clean fluids. Diaphragm valves, however, are better for corrosive, abrasive, or dirty fluids, as its design is leak-proof and resistant to contaminants.

Benefits:

• It seals strongly as the diaphragm is flexible.
• Non-aggressive and non-corrosive liquids are good.
• They are quite suitable for sanitary applications as they can be easily cleaned and sterilized.
• Precise Controlling of Flow.
