DESCRIPTION
Experience the power of precision with our Hydraulic Lock Valve, specially designed for forklift attachments. This sophisticated valve features a remarkable silent check function, allowing fluid to flow freely from port 2 to port 1, even at minimal differential pressures, effectively performing as a check valve. Meanwhile, any reverse flow from 2 to 1 is ingeniously blocked, ensuring exceptionally low leakage. When pressure at port 3 surpasses the combined resistance at port 1 and the spring force, seamless flow from port 1 to port 2 is enabled. Furthermore, port 4's presence mitigates the influence of pressure 3, and if pressure at 3 exceeds 4, it elegantly opens the channel from 2 to 1, showcasing an advanced level of hydraulic control.
