Buying Guide

Match thread type and size

Confirm NPT thread compatibility with your existing piping; the listed valves use NPT threading in multiple diameters to fit standard HVAC runs

Choose the right material

Brass offers corrosion resistance and durability for HVAC water and chilled-water systems; all featured valves are brass construction

Pick an appropriate valve diameter

Valve internal diameter (e.g., 1-1/2" to 3") should match system flow requirements to avoid restriction or excessive pressure drop

Consider handle and operation style

Wheel handles provide precise flow control while rotary sluice designs on larger valves can suit industrial-style shutoff needs

Check connection configuration

Confirm female x female or other connection types match your fittings; the roundup includes both inline female-female NPT options and single-end fittings
