DESCRIPTION
The ingenious design of the Non-Return Valve with Spring-Loaded Mechanism for Forklift Applications ensures flawless functionality under various conditions. It allows seamless flow from port 2 to port 1 with minimal differential pressure, acting efficiently as a check valve. Flow in the opposite direction, from port 2 to port 1, is securely blocked, maintaining exceptionally low leakage. When pressure at port 3 rises to overcome the force at port 1 and the spring tension, the valve permits unrestricted flow from port 1 to port 2. Port 4 acts as a safeguard, nullifying the influence of port 3, enabling flow from port 2 to port 1 when port 3's pressure surpasses that of port 4.
