Buying Guide

Match voltage and coil type

Confirm the valve’s coil voltage (12V DC, 24V, 110VAC) matches your system to avoid compatibility or wiring issues

Choose appropriate port size and thread

Select the port size (for example 1/8 in or 3/4 in) and thread type that fit your piping or fittings to prevent leaks and extra adapters

Consider body material for media

Brass works for many fluids including gasoline-compatible uses, while stainless steel provides better corrosion resistance for harsh environments

Verify normally-open vs normally-closed

Pick the correct default state (normally-closed or normally-open) for your control logic to ensure safe default behavior

Prioritize proven application fit

Use valves tagged for your task—boost control, vacuum repair, zone-valve motors, or general fluid control—to ensure functional suitability
