Non-adjustable Gas Safety Valves
View our wide range of non-adjustable gas safety valves that are used to vent overpressure in your system. A safety valve vents the medium to prevent pressure build-up, thereby increasing the safety of the system. These valves can not adjust the set pressure, so this needs to be known when specified. Once the pressure reaches this limit it will immediately fully open to release the excess pressure. This is usually accompanied by a popping sound. When the system’s pressure goes back down to the set pressure limit, the valve will close. This keeps downstream equipment and people safe from the dangers of overpressure in a system. These safety valves are specifically made for gas-based applications and therefore not suitable for systems transporting liquids.
