Hydraulic Shock Arrestors
HydroGuard
™
HydroGuard
™
shock arrestors are specially designed for hydraulic hammer arresting applications.
They are built to reduce or eliminate hydraulic shock, otherwise known as water hammer. They do this by
absorbing pressure surges within the water or other fluids that are suddenly stopped or forced in other
directions by fast closing valves. HydroGuard
™
shock arrestors are best used at the point of shock and
should be installed as close to the valve or piping where the shock originates.
HydroGuard
™
shock arrestors are designed with the latest diaphragm technology. A high-grade butyl
diaphragm is sealed inside the vessel creating a barrier between fluid and air chambers. The air chamber
acts as a cushion which compresses when system pressure suddenly increases or surges as a result of
hydraulic shock. HydroGuard
™
shock arrestors are quality tested at several stages along the production
line to ensure overall structural integrity.
HydroGuard
™
shock arrestors represent the best value for your investment and are the highest quality
shock arrestors available in the market!
