The Tandy CV08-B-1.7 is a high-performance, poppet-type, screw-in hydraulic cartridge check valve. It is engineered to allow free flow from the valve port (port 1) to the nose (port 2), while reliably blocking flow in the opposite direction. Designed for insertion into a standard T-8A (SAE-08) cavity, this valve is ideal for preventing reverse flow, maintaining pressure, or isolating specific circuits within a hydraulic system. Its robust construction ensures durability and consistent performance in demanding applications, making it a dependable choice for industrial and mobile hydraulic systems.
