Description

The 2/2 way direct acting motorized valve has a 4,2 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 off function. This valve has been specifically developed for applications that require continuous adjustment of the flow rate. Thus, the flow rate can easily be controlled depending on the required amount withdrawn easily. By incorporating the motorized valve in thermostatically controlled heating systems, the flow rate in the system can be controlled automatically according to ambient temperature in the room, for example. The stepper motor drive part of the valve is completely separated from the medium by means of special PTFE bellows. Technical changes reserved.
