Latching Valves 101
Understanding how to use an air valve with vacuum can be valuable information, because air valves can be easier to source and less expensive than valves designed specifically for vacuum applications. Check out this quick video to learn more.

Hi, I’m Mike Kettering, Product Manager for electronic valves at Clippard. What is a latching valve? A latching valve is an electronically actuated two-position valve that stays detented in the last position that it was actuated into. Just like a detented toggle stays in the last position that it was actuated to, a latching valve remains in the same state that it was actuated to.
I’ve never been over the pond, but apparently in Europe, these are commonly referred to as bi-polar valves.
The main benefit of using a latching valve is low power consumption. Since the valve only requires a pulse of power to change states, it can stay unpowered until the state needs to be changed.
Clippard offers a two-wire, 10 mm latching valve as well as a three-wire 15 mm latching valve. To change the state of a 10 mm latching valve, the polarity to the coil simply needs to be inverted. The 15 mm latching valve is a three wire valve with one wire to actuate, one wire to de-actuate, and one common wire.
