What is the approximate closing force of a direct-acting solenoid valve?

The approximate closing force of a direct-acting solenoid valve is typically around 25 lbs. This value is based on the operational characteristics of solenoid valves, which are designed to convert electrical energy into mechanical energy to control fluid flow.

In the context of hydraulic systems, the closing force is essential as it ensures that the valve seals properly to prevent fluid from leaking when the valve is in the closed position. The force needs to be sufficient to overcome the pressure of the fluid acting on the valve seat while also accounting for any friction in the mechanism.

While other values might seem plausible, the design standard and common manufacturing practices usually lead to a closing force in the range of approximately 25 lbs. This aligns with calculations based on the dimensions and performance criteria of typical solenoid valves used in hydraulic applications. Understanding this characteristic helps in selecting appropriate components for a hydraulic system, ensuring reliable operation.
