Parker RL4 Relief Valves are designed such that when the upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve. Flow through the valve increases proportionately to the increase in upstream pressure. The manual override option with positive stem retraction is available for the full working pressure ranges. This option permits the user to relieve upstream pressure while maintaining the predetermined cracking pressure.

Application: In the key markets of chemical & refining, food, beverage & dairy, medical & dental, microelectronics, oil & gas, and power generation.
