    LOW WATT VALVES
   Series 50 LW >> Model LW51
Low Wattage — 2-Way Normally Open Valve
General purpose for pneumatic and hydraulic applications. The versatility of these valves is increased to include the handling of hot air, hot water, refrigerants and many other media, by the use of different seals. Air
and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many media require special
seal materials.
• General purpose valve with reduced power consumption. • Increased versatility.
• For pneumatic and hydraulic application.
 Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
Media: Air and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many media require special seal materials. (Series 50 pressure ratings may change due to the viscosity of the liquid.)*
