Direct Acting Latching Valves are current-actuated

January 8, 2008 - Available as 2-way model MI 210 and 3-way model PI 300, both valves provide positive positioning in actuated state without continued application of current. Products have 2 stable positions and are constructed with brass bodies and stainless steel internal parts. Power consumption is 2.5 W, with standard available voltages of 6, 9, 12, and 24 Vdc, and flow rate (Cv) is 0.035.

Humphrey Introduces MI 210 and PI300 Direct Acting Latching Valves

Humphrey Products Company has introduced two latching valves, the model MI 210 2-way direct acting latching valve and the model PI 300 3-way direct acting latching valve. Both valves are designed to provide positive positioning in the actuated state without the continued application of current.

The Humphrey Latching Valves have two stable positions - in the spring rest position a spring pushes the plunger with the sealing element against the valve seat. When a short current impulse is applied, the plunger is lifted up from the valve seat and a built-in permanent magnet holds it in the magnetic rest position. A short, reverse polarity current impulse pushes the plunger back into the spring rest position, closing the valve.

Both the model MI 210 and model PI300 feature brass bodies with stainless steel internal parts and a flow rate (Cv) of 0.035. The power consumption is 2.5 watts, with standard available voltages of 6, 9, 12 and 24 VDC.
