How HydroGuard™ Shock Arrestors Work

HydroGuard™ shock arrestors absorb pressure surges within waters or other fluids that are suddenly stopped or forced into other directions by fast closing valves.  A high-grade butyl diaphragm is sealed within the vessel creating a barrier between the fluid and a compressible air chamber.  The air acts as a cushion which compresses when the system pressure suddenly increases as a result of hydraulic shock.  HydroGuard™ shock arrestors are best used at the point of shock and should be installed close to the valve or piping where shock originates from.
