Festo GRLA Series Pressure Relief Valve

Keep your pneumatic machinery on an even keel with this Festo pressure relief valve. With its one-way flow, it releases air without taking more in, to keep your system pressure at the right level. The adjusting element is a simple slotted screw, so it's easy to fine-tune the unit to meet your needs. Sudden movements are no problem, thanks to the secure threaded mounting port. As the valve has a standard G1/8 pneumatic connection, it's widely compatible with commonly used parts.
