Relief Valves

Relief valves are a safety device that prevent pressure from exceeding the maximum allowable working pressure. The relief valve minimizes the risk of any catastrophic failures and it protects other components of the system. Relief valves are spring loaded which mean they open in response to the system pressure. 

Relief valves are typically used in potable water applications and are specifically designed for installation on cold water service lines. They are available in a variety of materials including brass, stainless steel and PVC.
