Common Applications
The Control Valve Steam (CVS) is a characterized control valve and is ideal for use in fan coils, unit ventilators and low pressure steam. The CVS is available in both fail-safe and non fail-safe applications.
Operations
The Siral CVS is an electronically actuated characterized control ball valve. Control signal options include on/off, floating point or modulating (proportional) and are used to determine the final positioning of the ball rotataion angle which determines the amount of flow through the valve.
