Series 30 Model 31

2-Way Normally Open Valve

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.
