Relief Valve is a safety valve specifically created to safeguard a pressurized device or system from an over-pressurized situation. An over-pressurized problem occurs when a device generates enough pressure beyond its threshold limit value. Since enough pressure might lead to hardware failure or fire in worse conditions, so it is of utmost importance that a relief valve is installed in your device.

A relief valve works by releasing the pressurized fluid out from an additional passage from the system. The relief valve, also referred to as pressure relief valve, must open at a pre-agreed set pressure; allow a noted capacity of fluid to flow at a denied overpressure and automatically close when the pressure of the device has reached a stable and secure point.

Moreover, these valves are commonly designed with elements that are well suited with the process fluids, ranging from air or water to the most abrasive media.
