Water, Air, Steam Systems 3/4'' PN16 Stainless Steel 304 Safety Relief Valve
Safety relief valve - A pressure relief valve characterised by rapid opening or pop action,
or by opening in proportion to the increase in pressure over the opening pressure, depending
on the application, and which may be used either for liquid or compressible fluid.
Safety Valve - How They Work
A safety valve is a safety device designed to control the pressure in the system. If the pressure is
uncontrolled, it can build up in the system causing equipment failure, explosions or fire hazards.
This valve is designed to open at a predetermined pressure to avoid equipment failure as a result
of being subjected to the pressure that exceeds there design limits. Once the valve opens due to
excess pressure, the media is discharged until the pressure drops to it's acceptable limit and the
valve is than automatically closed.
Standard safety valve, complete with carbon filled PTFE valve seal, closed bonnet, gastight Outlet:
female thread Rc 3/8 acc. to ISO 7/1 "cleaned and degreased for oxygen service"
Applications:
Provided as safety device for protection against thermal expansion in pipeworks and parts of facilities.
Approved for air gases, vapours and cryogenic liquefied gases incl. LNG.
Working temperature: -196°C / -321°F (77K) up to +65°C / +149°F (338K), suitable for horizontal installation
