Paramètres de performance principaux
To start with, working temperature ranges from‑29℃ up to +425℃. Next, nominal pressure reaches PN16. What is more, it supports on‑site pressure setting adjustment. Also, flange dimensions follow ASME B16.5 and GB/T industry norms. Meanwhile, manual lever enables periodic functional test. Last but not least, every finished unit completes full‑set pressure calibration before delivery.
Points clés de vente
For one thing, built‑in spring triggers fast pressure release. For another, external lever simplifies routine function checking. On top of that, WCB cast steel body withstands high‑temperature steam. In turn, precise nozzle guarantees stable opening‑closing pressure. Apart from that, full factory calibration cuts your on‑site debugging work. Equally important, this Safety Relief Valve prevents dangerous overpressure damage for pressure equipment.
Avis de vrais clients
Many industrial plant operators share real‑world usage reviews. First, boiler station users trust its accurate pressure popping action. Second, chemical factory engineers value convenient lever test function. Third, equipment contractors approve strict factory calibration procedure. Even so, buyers must confirm set pressure and medium type before bulk purchase.
Large application
Above all, it safeguards industrial steam boiler systems. Next, it fits pressure vessels for gas and liquid storage. Then, it works for power plant and heating station pipelines. Additionally, it applies to petrochemical and light‑industry pressure equipment. Finally, it supports energy manufacturing over‑pressure safety workflows.
En conclusion, notre Safety Relief Valve offers robust and trusted pressure‑relief safeguard for high‑pressure industrial facilities. If you hunt for qualified overpressure protection hardware, this Safety Relief Valve meets your system safety demands perfectly.
