Safety Relief Valve spring loaded lever steam pressure protection boiler
This Safety Relief Valve complies with GB/ASME standards, DN25‑DN150 WCB cast steel. It protects boilers, pressure vessels for steam, gas, liquid media. Chinese factory delivers reliable over‑pressure release for energy and chemical industrial systems.
Safety Relief Valve: Spring‑Lever Over‑Pressure Protection for Pressure Vessel
Our Safety Relief Valve delivers dependable overpressure protection for pressure equipment. First of all, it adopts spring‑loaded structure with manual lever. Besides, the lever allows manual lifting test for regular inspection. Furthermore, it opens automatically when system pressure exceeds preset value. In addition, flange connection fits most industrial pressure vessels. Moreover, it works for steam, gas and non‑corrosive liquid working medium.

Core Performance Parameters
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.
Key Selling Points
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.
Real Client Feedback
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.
Wide 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.
In conclusion, our 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.
