The Hydraulic Check Valve functions when fluid pressure is exerted in the desired direction, it overcomes the valve's internal spring force and pressure, allowing fluid to flow through the valve. However, if the fluid tries to move in the opposite direction, the valve closes, blocking the passage and preventing backflow.Attributes:• Resistant to corrosion. • Maximum internal leakage is 0.25 milliliter per minute at 24000 Kilo Pascal.• Designed to withstand a maximum cracking pressure of 172 Kilo Pascal.Applications: The Hydraulic Check Valve is used in combination systems involving brakes, differential locks, and hydraulic fans to maintain the proper functioning of each component.
