Pneumatic Control Valve

A pneumatic control valve is an automated valve that uses compressed air through a pneumatic actuator to regulate flow rate and pressure in steam and process piping systems. This Robotrol-operated pneumatic control valve is built for boiler steam lines, utility systems, and industrial process pipelines where precise, repeatable control is required. Reliable Control for Demanding Applications The valve is engineered for heavy-duty service, providing smooth modulation of steam and process flows under varying load conditions. Its pneumatic actuation allows fast, accurate response to control signals, making it suitable for systems that need tight regulation of pressure or flow rate rather than simple on/off operation. Robust Construction Built with a flanged end connection for secure, leak-tight installation in industrial piping, this valve is designed to withstand the demanding conditions of steam and process environments. It is available in 40 NB and 50 NB sizes, with other sizes available on request. Where It Is Used The valve is commonly installed on boiler steam lines and in process plants where flow or pressure must be automatically controlled — including utility systems and other industrial pipelines carrying steam or process fluids.
