The Parker RAH101S50N is a high-performance, direct-acting, poppet-type, screw-in hydraulic cartridge valve. It is engineered to limit the pressure in a hydraulic circuit by diverting excess flow to the tank when the pressure reaches a preset level. This valve is designed for reliability and fast response, providing excellent protection for hydraulic system components against over-pressurization. Its robust construction and cartridge design allow for easy installation into standard C10-2 cavities, making it a versatile solution for various industrial and mobile hydraulic applications. This specific model comes with a fixed, non-adjustable pressure setting for tamper-proof operation.
