How can we improve?

30 Products

Fluid Handling

Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Check Valves

Permit flow in only one direction by closing when flow stops or reverses

Fastening and Joining

Welding Gas Flashback Arresters

Welding Gas Flashback Arresters

Attach to your gas welder to extinguish flames and stop reverse gas flow
