The Hydac RVM10120-01-C-N-0.5 is a high-quality, direct-acting screw-in cartridge check valve, also known as a one-way valve. Engineered with a poppet-type design, it permits free flow of hydraulic fluid in one direction while reliably blocking flow in the opposite direction. This valve is essential for preventing backflow, isolating circuit components, and maintaining pressure within a hydraulic system. Its robust construction and NBR seals ensure dependable, low-leakage performance in a wide range of industrial and mobile hydraulic applications.
