“Pop-type” relief valves are designed for use as secondary relief valves in carbon dioxide transports & stationary storage tanks. The relief valves are designed to protect tanks from excessive pressure in event of fire /other emergencies. Small throttling-type primary relief valves must be provided to control boil-off and maintain tank pressures. Provisions must be made to prevent accumulation and build-up of water and foreign material in valves.
- “Pop-type” design permits relief valve to open slightly to relieve moderately excessive pressures.
- Relief valve “pops” open to full discharge capacity when pressure exceeds a predetermined point.
