Heavy Duty Bronze Safety Relief Valve A Real Workhorse For Hot Water Systems With Rock Solid 75 Psi Set Pressure Plus 1-1/2 By 2 Inch Npt Female Threads Asme Certified For High Heat Up To 250 Degrees F Runs Smooth Every Time
✔️ 75 psi preset rating with one point five by two inch pipe threads
This heavy duty hot water control component releases excess system pressure to prevent damage in residential and commercial heating setups. Technicians install it directly onto plumbing lines where temperature and pressure regulators fail to maintain safe operating limits.
✅ Bronze chamber resists corrosion while maintaining structural integrity under stress✅ Steel tension spring pairs with EPDM diaphragm to isolate moving parts from fluids
✅ Factory calibrated seventy five pound psi cutoff activates before dangerous surges occur
✅ Meets ASME Section IV standards approved for residential and light commercial boilers
💡 What is a safety relief valve used for in hydronic heating circuits?
This pressure regulating device acts pretty handy when boilers encounter temperature spikes or failed control loops.
- Triggers automatic discharge pathways before internal vessel stress exceeds safe mechanical limits
- Shields associated piping assemblies and gauge clusters from irreversible thermal shock scenarios
- Delivers consistent performance across varied seasonal loads without needing frequent technician visits
