Servo-direct stepper motor controlled valve, DN 10
The 2/2 way servo-direct motorized valve has a 10 mm orifice, but a continuously variable stroke to accurately control the flow through the valve. It can function with low inlet pressures and flow rates, similar in nature to a direct acting valve without a complete shut of function.
The stepper motor drive part of the valve is completely separated from the medium by means of special PTFE bellows. This valve has been specifically developed for applications that require continuous adjustment of the flow rate. For example the flow through an instant flash heater can easily be regulated for maximum accuracy and efficiency.
Alternatively, by incorporating the motorized valve in thermostatically controlled heating systems, the flow rate into the system can be controlled according to ambient temperature in the room.
