What direction should the arrow stamped on the body of a solenoid valve point during installation?

The arrow stamped on the body of a solenoid valve is designed to indicate the direction of flow through the valve. When installing a solenoid valve, it is crucial to align the valve correctly according to this directional arrow to ensure proper operation. If the flow direction is not followed, it could result in inefficient system performance or fluid flow issues. Proper installation ensures that the valve opens and closes as intended, allowing the fluid to pass through in the designated direction, which is critical for systems relying on precise fluid control, such as hydraulic or pneumatic systems. This makes aligning the solenoid valve with the flow direction essential for effective and safe system functionality.
