Peter Paul Magnetic Latching Valve Model MLV 21

PeterPaul single orifice valves feature an orifice that is closed in the energized position, preventing any flow between the inlet and outlet ports. This type of valve is often used in remote areas where continuous power may not be available or with battery-powered portable equipment where power capacity is limited. It is also valuable in equipment where coil heating, due to the continuous application of power, is undesirable. These valves are compatible with air and other fluids when using standard Buna seals. Special seal materials are required for hot water, steam, gasoline, oils, some hydraulic fluids, and many other media.

Valve is magnetic latching.
Meets today’s demand for economy of space.
Uses power only during latching and un-latching.
Great for medical and chemical analyzers.
