Solenoid Valves 820 Series
The Pneumatic Solenoid Valves 820 Series are NC 2/2 type.
The research about materials and new technological solutions allowed the realization of a shutter solenoid valve with an extremely simple operation principle and with avant-garde dynamic characterist-ics. The mass of the moving elements has been reduced to the minimum and every inner friction has been eliminated: in this way, we obtained response times of milliseconds and an operation life over 500 million cycles.
Due to the possibility of controls of speed-up type, their dynamic characteristics are even more improved. Standard solenoid valves with 24 VDC control have a response time lower than 5 ms in open-ing and 2 ms in closing, with a maximum operation frequency of 200 Hz. On the contrary, solenoid valves with speed-up control have a response time lower than 1 ms, both in opening and in closing, with a maximum operation frequency of 500 Hz.
Besides high-speed characteristics, solenoid valves 820 Series offer flow rate values up to 180 dm3/min. (ANR), with feeding pressure from 0 to 8 bar.
Controlling the valve through either PWM (Pulse Width Modulation) or PFM (Pulse Frequency Modula-tion) technique, it is possible to vary the passing flow rate and to obtain, in this way, a solenoid valve, having a proportional flow rate.
820 Series is available both in-line assembly and sub-plate version, equipped with such accessories as multi-position manifolds or speed-up driver boards.
