Direct acting, stepper motor controlled valve DN 4,4

About this product

The 2/2 way direct acting motorized valve has a 4,4 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 Thus, the flow rate can easily be controlled depending on the required amount withdrawn easily.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.

Applications: - Thermostatically controlled heating system - Instant flash heater - Hot / cold drink dispensers - Industrial appliances - Air conditioning - Agricultural implements - Cleaning systems - Temperature equalisers - Dish washers - Washing machines - Water treatment

Characteristics: - Direct acting - stepper motor, medium separated by PTFE bellows - Long term performance capability - Suitable for hot water up to 80°C - continuous opertion - No water hammer - High operating safety through the use of high quality materials and 100% final testing of the products
