Modulating process control - steam, water and general process media.
A control valve modulates flow to a proportional setpoint rather than simply switching on or off - the actuator is paired with a positioner that drives the valve to any position between fully open and fully closed in response to a control signal.
We supply pneumatic control valves for steam, water and general process media, sized to line pressure, flow coefficient (Cv) and the specific media being controlled.
Actuated control valve for proportional (modulating) process control, not simple on-off isolation.
IllustrationPneumatically actuated angle-body valve for steam, hot water and process fluid switching - compact, fast-cycling.
Y-pattern globe-style control valve offering lower pressure drop than a standard globe body at full opening.
An on-off automated valve (e.g. an actuated ball valve) only opens or closes fully. A control valve, fitted with a positioner, can hold any intermediate position in response to a 4-20mA or pneumatic control signal - used for proportional process regulation like flow, pressure or temperature control loops.
