**PRODUCT DESCRIPTION**
This innovative One-Way Valve for Forklift Attachments with Pressure Control System exemplifies cutting-edge engineering. It seamlessly allows unrestricted flow from point 2 to 1 under minimal differential pressure, functioning as an exceptional check valve. Flow in the opposite direction, from 2 to 1, is effectively blocked with negligible leakage. When the pressure at point 3 rises sufficiently to counteract the resistance at point 1 along with the spring force, the valve permits free flow from point 1 to 2. Additionally, point 4 is adept at negating the influence of point 3. Should point 3's pressure exceed that of 4, it facilitates the opening of flow from 2 to 1, ensuring optimal performance in demanding conditions.
