A valve signature should always be captured for a new control valve. This procedure performs a number of test and measures control air pressure, valve position and set point.

These methods use different types of level control valves to manage the levels of liquids.

There are many types of control valves

T-shaped control valve has two switching positions that allow the dividing or mixing or the complete change of direction of the material flow.

There is a distinct difference between a flow-control valve and a flow restrictor. The flow-control valve restricts the flow of water to about 2.75 gals. per minute, automatically making adjustments for water-pressure changes.

Control valve has the characteristics of simple structures and reliable action. Because of its direct contact with technology media, its performance directly affects system quality and environmental pollution
