Peter Paul Hazardous Location Valve Model LW51

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.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (LW51J8XGML 120/60) repair pack (KLW51JX AC)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OLW51JDDGML 120/60)

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.)*

Valve Temperature Range: Standard Valves – 0°F (-18°C) to 140°F (60°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. *
