Miniature Check Valves

The F-2804 Series Small Check Valves permit flow in one direction only. Utilizing a small disc design, the valve shifts to seal off flow when pressure reverses.

Key Advantages:

• Low Cost & Miniature Size: Perfect for compact applications.
• Ultra-Low Cracking Pressure: Less than 0.005 PSI differential required for forward flow.
• No Residual Pressure: Zero pressure difference across the valve once flow ceases.
• High Flow Efficiency: Forward flow is relatively unrestricted (approx. equivalent to a 0.040" orifice).

Technical Specifications
