Valves &
Gauges
Valves and gauges for pressure washers, parts washers, waste oil heating systems, and wash bay plumbing, shipped nationwide. Ball valves, check valves, safety relief valves, thermal relief valves, fuel shutoffs, and glycerin-filled pressure and temperature gauges. Thermal relief is a small part doing a large job — it dumps water before a bypassing pump cooks itself, and it’s cheap to replace and expensive to ignore. Match on pressure rating, temperature rating, and port size.
