+ Ratings in brackets are optional extended ratings; consult factory.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (22N9DCM 120/60) repair pack (K22NDD 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 (O22N9DCM 120/60)

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.
