Thermal Relief Valve 1/2 GP
$13.00
Thermal Relief Valve 1/2 GP. A thermal relief valve dumps water once it exceeds a set temperature, protecting the pump from heat damage during extended bypass.
When a pump runs in bypass with the trigger off, the same water recirculates and heats quickly. Without thermal relief, that water can reach temperatures that destroy seals and packings in minutes.
Thermal relief valves are inexpensive, single-purpose safety devices. They should be tested periodically — a stuck valve provides no protection at all, and you won't know until the pump is already damaged.
Grime Task Force stocks valves, filters, and control components across the range because these are the parts that protect everything expensive on a rig — and the parts most likely to be the actual cause when a machine starts behaving badly.
