Specification Table of Pneumatic Diaphragm Operated Control Valve
Pneumatic Diaphragm Operated Control Valve is a type of control valve that uses a diaphragm to control the flow. The diaphragm is installed inside the body of the valve and is controlled by the air pressure. The Pneumatic Diaphragm Valves are easy to install and cost low to install. They also have optimized process designs. The number of welds and valves are low that the system is less complicated. The body of the valve is made up of stainless steel. The material for the body can vary based on the applications requirements and the material that flows inside the valve. There are different sizes and dimensions to the valves and pressure capacities vary with different pressure ratings.

The Pneumatic Diaphragm Actuator Operated Valve comes in sizes ranging from 2 inches to 48 inches and the pressure ratings vary from 150lbs to 900lbs. The valve sizes and pressure numbers are controlled by the standards and specifications. Industrial scale valves can come with higher pressure capacities and higher outlet sizes as well. The Pneumatic Control Valve is made to withstand corrosion and high air pressures. The diaphragm provides accuracy of control. The applications include water management systems, petroleum and oil and gas industrial applications. The Cast Steel Pneumatic Diaphragm Operated Control Valve is one of the most common types of body material but other materials are also in use.
