Series 50 LW Model LW53

Low Watt
3-Way Normally Closed Valve (piped exhaust)

General purpose valves 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.
• Increased to handle hot air, water and refrigerants.
• High quality engineering.
