About Control Valves

Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system. These valves are used throughout industry in many applications.  Control valves types include globe, diaphragm, pinch, knife or gate, needle, butterfly, ball, and plug. 

Products & Services Related to Control Valves

Air Pressure Regulators
Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices.
Air Valves
Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.
Diaphragm Valves
Diaphragm valves close by means of a flexible diaphragm attached to a compressor.
Plastic Valves
Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling.
Plug Valves
Quarter-turn plug valves use a cylindrical or tapered plug with a hole in the center to control straight through flow when in the open position.
Pressure Regulators
Pressure regulators are used to maintain a constant outlet pressure or flow.
Sanitary Valves
Sanitary valves are designed for applications requiring clean or sterile processing.
