AWP Safety Relief Valves SVA

Safety valves dependent on back pressure, spring-loaded.

Safety Relief Valves SVA

AWP safety valves are suitable for installation as relief or overflow valves in the refrigerant cycles of industrial refrigeration systems. Safety valves are safety devices for protecting the refrigeration systems and their components from excess pressure (see also EN 378 part 2). They comply with AD2000 regulations. AWP safety valves open up to the valve lift stop if the start-to-leak pressure (set pressure) rises within the 10% range. They close if the pressure drops to the 10% range below the set point. AWP safety valves are maintenance-free. Any defects that occur in the functional performance of the valves can be repaired.
