Purchase now: Winner CV-08W-20-Y-N-2 Check Valve
Purchase now: Atlantech Drives provides you the Winner Hydraulics CV-08W-20-Y-N-2, a high-quality Screw-in Cartridge Check Valve. Designed for the standard C-08-2 Cavity (Size 08), this valve acts as a one-way street for hydraulic fluid, preventing reverse flow and holding load pressure securely. The «CV-08W» series typically designates a direct-acting poppet design, which offers extremely low internal leakage, making it superior to spool valves for load-holding applications.
Technical Specifications and Cracking Pressure
This specific model is configured with a 2.0 Bar (approx 29 PSI) cracking pressure (indicated by the «20» code, subject to verification). This means the valve remains closed until the inlet pressure exceeds 2.0 bar, making it useful for creating a slight backpressure in return lines to prevent cavitation or emptying of cylinders. It features Buna-N Seals («N» code), compatible with standard mineral-based hydraulic oils (HLP/HM) used in mobile equipment and industrial power units.

Expert Tips: Why Cracking Pressure Matters
Don’t just swap any valve. Expert Tip: The cracking pressure is not random. Using a 2.0 bar spring in a suction line (where you need 0.3 bar) will cause pump cavitation and catastrophic failure. Conversely, using a 0.3 bar spring in a bypass cooling loop might not force enough oil through the cooler. Always replace with the exact pressure code («20») to maintain the thermal balance of your system.
Frequently Asked Questions (FAQs)
Q: What is the flow direction?
A: Standard Winner CV-08 valves allow free flow from Port 1 to Port 2. However, «W» models sometimes reverse this (2 to 1). Always check the stamped symbol on the hex body before installation.
Q: Can I use it with biodegradable oil?
A: Buna-N seals are generally not recommended for biodegradable esters (HEES). For eco-fluids, look for the Viton («V») version.
