Surge Arresting - Automatically prevents water hammer pressure surges associated with air release valves operation.Optimum performance - Air outlet can be adjusted according to surge analysis results, on site to a required aero-dynamic performance. The SA addition is assembled on user selected valves only (at local high elevated points). The flow through other valves remains unrestricted.Reliability - Simple, durable mechanism, Can be serviced without having to put the air valve out of service.
