Series 30 Model 31

2-WAY NORMALLY OPEN

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.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (31K5XGM 120/60) repair pack (K31KDX 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 (O31K5DGM 120/60)
