The safety pressure relief valve is designed for reliable overpressure protection in pipeline systems and downstream equipment. This low-flow proportional relief valve remains closed during normal operation and opens automatically only when the system pressure reaches the preset setting, safely releasing excess pressure before closing again once pressure returns to normal. With a maximum inlet pressure of 300 psig (20.6 bar), a maximum allowable outlet pressure of 225 psig (15.5 bar), and an adjustable set pressure range from 10 to 225 psig (0.7 to 15.5 bar), this valve provides precise pressure control in demanding applications. It features an internal orifice of 4.8 mm, an operating temperature range of -40°C to 300°C, an adjustable bonnet cap for pressure setting, and a locking design with lead seal wire to help maintain the preset pressure. This safety pressure relief valve is an ideal solution for protecting piping systems and preventing damage caused by excessive pressure.
