Buying Guide

Match valve type to system

Choose steam-radiator vents for radiator systems and 4-way manual air valves for pneumatic control to ensure functional compatibility

Check thread and port sizes

Confirm thread types like 1-1/4 FIP, 1-1/2 FIP, 1/8-inch NPT or 1/8-inch ports to match existing fittings and unions

Prefer brass or heavy-duty construction

Brass-bodied valves resist corrosion and withstand steam or water exposure better than cheaper alloys

Consider adjustability and orientation

Adjustable vents and 90° fittings allow easier alignment and fine-tuning of flow or venting in tight spaces

Evaluate manual control needs

Manual 2-position or 4-way valves are simple and reliable for on/off routing without power or pneumatics
