What is the main flow direction through most solenoid valves compared to globe valves?

In most solenoid valves, the main flow direction is downward through the valve seat. This design typically allows for an effective and direct path for the fluid as it enters the valve and exits towards the downstream side. Solenoid valves are often used in applications where a quick and reliable actuation is needed to start or stop the flow of fluid. The downward flow arrangement enhances the performance of the valve by leveraging gravity assist when the valve is in its open position.

In contrast, globe valves can have flow paths that may be different from a straightforward vertical orientation due to their design, which is intended for regulation and throttling of flow rather than just open/close functionality. This is why it is important to understand the specific flow characteristics of each type of valve in practical applications, especially concerning how gravity influences performance. Understanding this distinction helps in selecting the right valve for a given application and ensuring optimal system performance.
