Buying Guide

Choose the right body material

Stainless steel resists corrosion in humid greenhouse environments while brass offers cost-effective durability for many water systems

Match valve voltage to your controller

Confirm your irrigation controller or relay supplies 110VAC power; all featured valves use 110VAC so wiring and relay ratings must match

Pick the correct port size

Select 1/2-inch or 3/4-inch ports to match your piping to avoid adapters that can reduce flow or create leaks

Check seal material for water chemistry

Viton seals tolerate chlorinated or treated water better than generic elastomers, extending valve life in nutrient or sanitizer-treated systems

Consider normally closed vs. normally open

Most greenhouse systems use normally closed (N.C.) valves to stop flow when de-energized; choose based on fail-safe needs and wiring logic
