The Altecnic series 513 safety relief valves are used in large domestic hot and cold water service systems to protect the hot water cylinder and components in the cold water system.
The outlet port is one size larger than the inlet port enabling the valves
to discharge large volumes of water quickly preventing excess pressure
from causing serious damage to the system.
The discharge capacities for cold water are the result of actual testing
conducted during development of the valves.
