Overview
A compact, spring-loaded pop-type thermal relief valve with full stainless steel construction, engineered to protect closed-loop liquid systems from overpressure caused by thermal expansion. Designed for pump discharge lines, heat exchanger jackets, condensate return systems, jacketed piping, and tank coils, with minimal leakage and low maintenance in demanding industrial service. Supplied, set and serviced for process plants across Nepal.
Features & Benefits
- Pop-type spring-loaded mechanism gives a fast, sharp opening response the moment system pressure exceeds the set point, which matters in thermal expansion scenarios where pressure can rise quickly.
- Soft seat construction ensures bubble-tight shutoff after reseating, preventing cumulative leakage losses in closed-loop systems that would otherwise cause pressure drift over time.
- Full stainless steel wetted parts resist corrosion from condensate, process chemicals, and hot fluids, making this a long-service-life device with minimal replacement cycles.
- Compact body keeps installation footprint small, which is practical for tight locations like pump discharge flanges and jacketed pipe branches.
- Flanged end to ASME B16.5 standard integrates cleanly into flanged piping systems without adapter hardware, simplifying installation and inspection access.
- Vertical installation orientation ensures consistent spring loading and repeatable set-pressure performance across the operating life of the valve.
