GENERAL PURPOSE VALVES
Series 30 >> Model 33
3-Way Normally Closed Valve — Piped Exhaust
Complete range of valves particularly suitable when cost and size are major factors. The bodies are constructed of brass (stainless steel is optional). Air, water, and other fluids compatible with 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.
Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
