Atlas manufactures a Flow Control Valve that is hydraulically operated and throttled to maintain a preset flow rate and/or limit the maximum flow rate regardless of changing upstream and downstream pressures.
The throttled position of the main valve is controlled by an adjustable pilot valve which senses pressure across an orifice plate.
As the flow rates tend to vary because of changing line pressures or downstream demand, the differential pressure across the orifice plate also tends to vary. When this occurs, the pilot valve repositions to compensate, and changes the throttled position of the main valve piston which controls and maintains the desired flow rate.
Atlas flow control valves regulate the flow or pressure of a fluid. Flow control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Atlas flow control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used.
