Full-lift structure, disc lift ≥1/4 of nozzle diameter, large discharge capacity. Closed bonnet, no manual lifting wrench.
02
Hard-alloy overlay sealing surface
Disc and seat overlaid with stellite hard alloy, anti-erosion, reliable sealing performance, long service life.
03
API standard pound-grade design
Designed per API-526, tested per API-527; flange ASME B16.5; pressure class Class150-600.
04
Working parameters
Body WCB carbon steel; working temperature-29℃ ~ 300℃; applicable for gas, steam and liquid media.
05
Limitation：Not suitable for medium containing solid particles, particles will damage bellows.
Typical Application Equipment
- Petrochemical & refining pressure vessels and process pipelines
- Toxic, harmful, flammable & corrosive medium pressure systems
- Working conditions with fluctuating outlet back-pressure
- Heat exchangers, separation towers and storage tanks
- Chemical fertilizer, fine-chemical process equipment
Full lift safety valve applies for gas, steam and liquid systems with temperature-29℃ ~ 300℃. Built-in bellows counteracts fluctuating back-pressure. When system pressure exceeds set value, the valve opens fully to discharge medium. When pressure drops back to allowable value, full lift safety valve closes automatically to protect equipment and pipelines. Suitable for toxic, corrosive media and conditions with variable back-pressure.
