Purchase now: Winner CV-08W-2A-Y-Z Check Valve
Purchase now: Atlantech Drives provides you the Winner Hydraulics CV-08W-2A-Y-Z, a specialized Hydraulic Check Valve for compact manifold integration. Fitting into the industry-standard Size 08 cavity, this cartridge prevents backflow in hydraulic circuits, protecting pumps from pressure spikes and ensuring actuators stay locked in position when the pump is turned off. The «2A» designation points to a specific Cracking Pressure setting, typically calibrated for lower pressure opening (e.g., 0.2 – 0.5 Bar) to minimize pressure drop across the valve.
Technical Specifications and Zinc Plating
The «Z» in the part number often indicates a Zinc Plated surface treatment on the exposed hex body, providing superior corrosion resistance compared to standard black oxide, especially in mobile applications (trucks, agricultural machinery) exposed to rain and salt. The valve utilizes a hardened steel poppet and seat, precision-ground to ensure a metal-to-metal seal that improves with pressure. This robust construction allows it to withstand system pressures up to 350 Bar.

Expert Installation Advice: Cleanliness
Poppets hate dirt. Expert Tip: A check valve is the simplest valve, but also the most prone to being held open by debris. A single metal chip from a poorly threaded manifold can lodge between the poppet and the seat, causing the load to drift (drop). Always flush the cavity with clean fluid before screwing in the CV-08W-2A-Y-Z and torque it to specification (approx 25-30 Nm) to avoid distorting the seat.
Frequently Asked Questions (FAQs)
Q: Is this a Pilot Operated check valve?
A: No, the «CV» series is typically Direct Acting. It opens purely based on flow pressure. For Pilot Operated (to open the valve in reverse), you need the «PC» or «RP» series.
Q: What does the «Y» stand for?
A: In Winner nomenclature, «Y» usually refers to the internal spring retainer type or a seal variation. For replacement, simply match the full code to ensure dimensional compatibility.
