A hydro valve, often referring to a hydraulic check valve in this context, allows hydraulic fluid to flow in only one direction within a hydraulic system.
Here's a breakdown of how it works, based on the provided reference:
- One-Way Flow: The valve's primary function is to ensure unidirectional flow. It's positioned between the pump and the hydraulic cylinder.
- Internal Mechanism: Inside the valve, there's a mechanism (likely a poppet, ball, or cone) that either opens or closes the passage based on the fluid pressure.
- Forward Flow: When the hydraulic fluid pressure from the pump is high enough, it overcomes the spring pressure (if any) or the weight of the closing element, pushing it open. This allows the fluid to flow freely through the valve toward the cylinder.
- Reverse Flow Prevention: If the pressure attempts to reverse (e.g., fluid trying to flow back from the cylinder toward the pump), the pressure forces the poppet, ball, or cone against its seat, creating a seal and preventing any backflow.
In essence, the hydraulic check valve operates as a simple "one-way street" for hydraulic fluid, controlling the direction of force and movement within the hydraulic system.
