DIATROL® ASME D Series
Water is contained in an NSF61 listed bladder. This provides a completely non-metallic water reservoir, eliminating any contact of system water with metal.
When a sudden valve closure occurs, the resulting pressure surge travels back from the valve to the bladder type shock suppressor forcing the bladder to expand into the air cushion.
The shock is absorbed by the compressing of the air. After absorption of the shock, the system water pressure and the air chamber pressure equalize at the static pressure level.
