Thermal Relief Valves

Thermal relief valves open automatically when heat-driven expansion pushes pressure beyond safe limits. That simple action prevents pipes from bulging or bursting, keeping equipment intact.

Each of our thermal relief valve is built to match its service conditions. Spring tension, seat size and body material are selected based on fluid type and maximum temperature. Every unit is bench-tested to hold its rated pressure plus a small safety margin, then to vent precisely when that limit is reached.

Recognizing that system requirements vary from one installation to the next, Pressure Systems supplies a comprehensive range of thermal relief valves. We have a range of body materials, pressure ratings and connection styles. Whichever industry you work (oil, gas, chemical plants, HVAC systems, etc.), Pressure Systems has got you covered.

Beyond product excellence, we also take pride in our exceptional customer service. Pressure Systems couples each valve with hands-on technical support from the first inquiry through long-term operation. Pre-sales engineers evaluate flow rates, temperature limits and piping layouts to pinpoint the ideal valve model. After delivery, commissioning specialists confirm correct installation, set activation points and validate performance.

Pressure Systems offers thermal relief valves honed by more than forty years of valve-engineering experience. Every unit meets strict manufacturing and testing benchmarks, backed by a nationwide support network and ready access to spare components. The result is reliable protection against overpressure from thermal expansion, delivered without slowing down your processes.
