MAGNET LATCHING VALVES
Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
Media: Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials. (Series 20 pressure ratings may change due to the viscosity of the liquid.)*
Valve Temperature Range: Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient;
0°F (-18°C) to 150°F (65°C) media. Optional Valves – can tolerate much higher or much lower ambient and media temperatures.
Maximum Operating Pressure Differentials: See table on proceeding page. Burst Pressure: 5000 PSI
Leakage: Bubble tight for standard valves.
Vacuum: To 5 Microns*
ELECTRICAL CHARACTERISTICS
Coil Voltage: 6 to 60V DC Nominal Power: DC — 10.0 Watts
DE-ENERGIZED (OFF)
ENERGIZED (ON)

3-Way Normally Closed Magnet Latching Valve —
Piped Exhaust
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 continuous application of power, is undesirable. Air and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.
• Meets today’s demand for economy of space.
• Uses power only during latching and un-latching. • Great for medical and chemical analyzers.
