The ATOS HQ-022 is a high-performance, direct-acting modular pressure relief valve of the poppet type. It is designed for subplate or manifold mounting according to ISO 4401 size 06 (CETOP 03) standards, allowing for easy integration into hydraulic systems. This valve provides reliable pressure limitation in a hydraulic circuit by diverting excess flow to the tank when the set pressure is reached. Its robust construction ensures long service life and consistent performance in demanding industrial applications. The pressure setting is easily adjustable via a hexagon socket screw, providing precise control over your system’s operating pressure.
