This microvalve operates extremely quietly
The Type 6712 Whisper Valve (photo) is a microvalve with a height of 26 mm and a width of 7 mm, making it small enough to fit inside a miniature apparatus. The low overall weight of the Type 6712 is an advantage in dispensing, pipetting and dosing applications. With its non-impact actuator, the Type 6712 can control flowrate very quietly. The new actuator is designed to operate at a sound level below 36 dB, and the typical metal-to-metal contact noise of a solenoid valve is eliminated. Compared to similar-sized valves, the working pressure range of Type 6712 valves is very high, at 3 bars during switching and 8 bars during the flushing process of the open valve.
