Dispense valve, proportional, DN 8
2/2-way solenoid proportional valve of nominal diameter DN 8 for controlled liquid dispense. This valve is direct acting and normally closed (NC). This control valve is particularly suitable for demanding dosing tasks due to its good response characteristics.
Valves of this design are medium separated seat valves, where the plunger is separated by a diaphragm from the medium. The valve seat is made of scale build up inhibiting PTFE.
The valve is controlled by a PWM signal (pulse width modulation). The pulse duty factor of the PWM signal determines the coil current and therefore the opening behaviour of the valve. Thus, it can be continuously adjusted to a value between 0 and 100% of the maximum flow rate by altering the coil current.
Also, control by an adjustable current source is possible.
The valve is also available in other PSU housing variants on request and is distinguished primarily by its food grade and hot water capability.
