Series 30 Model 33

3-WAY NORMALLY CLOSED (e to a)

A complete range of valves that is particularly suitable when cost and size are major factors. The bodies are constructed of brass (stainless steel is optional). Compatible with air, water, and other fluids using standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials.

Brass body with stainless steel internal construction.
A smaller, cost effective alternative to any industry standard.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (33JJ5DCM 120/60) repair pack (K33JJD 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 (O33JJ5DCM 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 30 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.*
