Globe Control Valve Diaphragm Operated or pneumatic operated is available in the market in different sizes and dimensions. The valve uses a globe and is known as a globe valve where a valve that uses a ball for the control of flow is known as the ball valve. The Globe Control Valve has a globe shaped disc inside the body and is fitted in parallel to the pipeline. The globe is connected to a central axis that is turned sideways by the handle attached to it. The diaphragm operated control valves have diaphragms to control the flow. The diaphragms often are operated by air pressure and are called pneumatic diaphragm operated valves. The two can be joint together to make a valve that is accurate, pressure sensitive and has optimal design advantage.

GG25 Cast Iron 3 Way Globe Control Valve
These are the Stainless Steel Globe Control Valve Diaphragm Operated types and can come in different dimensions and sizes. The size of the valve inlet and outlet ranges from 2 inches to 48 inches with different materials being used. The materials vary as stainless steel, austenitic, duplex and alloy steel but the Cast Steel Globe Control Valve and the carbon steel valves are more common. The pressure capacities of the valves also vary from 150lbs to 2500lbs depending on the pressure requirements. Higher and lower pressure valves are also available upon customer requirements.
