AN ISO 9001:2008 CERTIFIED COMPANY
Safety Valve
FEATURE :
APPLICATION :
DESIGN STANDARD :
- The Cr-V spring & novel disc & seat design provide reliable
bubble – tight seal.
- Excellent re-seating ability
- It features heavy-duty hood & lever mechanism, and a short tuned
blow-down which adjusted with a single ring to meet specific requirement
- It could use for ASME section VIII application at 150psig pressure rating.
- Boilers, piping lines and vessel protection, including fired and
unfired pressure vessels.
- Power plants and heat exchangers cycles.
- Pressure reduction & air system.
- Chemical and pharmaceutical plants & food industry too.
- Refineries and pulp & paper mills.
- Pressure booster systems of water & air.
- ASME VIII Sec.-1
- IBR-1950
