Buying Guide

Match voltage and power

Confirm the valve’s operating voltage (12V DC, 110VAC, 24V) to ensure compatibility with your system and avoid wiring or control issues

Check port size and thread type

Select the correct port size (1/8 in, 1/2 in, 3/4 in) and thread standard to fit existing plumbing or boost-control fittings without adapters

Choose material for the fluid

Brass bodies are common for water, fuel, and gasoline-compatible use, while other materials may be better for corrosive fluids—match material to media

Confirm normally-open vs normally-closed

Verify whether the valve is normally-closed or normally-open to ensure correct fail-safe behavior in power-loss or control scenarios

Consider application-specific features

For boost-control or vacuum repair, prioritize valves labeled for boost control or specific appliance models; for zone valves, look for compatible replacement motors
