Globe Valve Suppliers
Valvesonly Europe are reputed Globe Valve Suppliers in Germany. A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a still ring seat in a generally spherical body. The valve body is designed with a linear motion mechanism that allows precise throttling, making it ideal for applications requiring flow regulation and frequent operation. The globe valve’s disk can be completely removed from the flow path or it can completely close the flow path, ensuring effective shut-off capabilities. These valves are known for their robustness and are widely used in systems where flow control, rather than just on/off control, is essential, such as in cooling water systems, fuel oil systems, and chemical feed systems. The design of a globe valve allows for a wide range of flow rates and ensures minimal leakage when closed, with their design often featuring ports in a straight-line or angle pattern to suit various piping configurations.
How does Globe Valve work?
- The main parts of a globe valve include the body, bonnet, stem, disk, seat, and actuator.
- The fluid enters the valve body, flows through the seat region, and exits the valve. The path of the flow is typically in an S-shaped curve, entering the valve body and making a 90-degree turn to pass through the seat area, then making another turn to exit.
- The disk or plug, connected to the stem, is positioned above the seat. The actuator controls the movement of the stem. When the actuator turns the stem, it moves the disk up or down.
- When the disk is lifted away from the seat by turning the actuator, the valve opens, allowing fluid to pass through. The degree of opening can be adjusted to control the flow rate.
- When the disk is lowered onto the seat, it blocks the path of the flow, sealing the valve and stopping fluid flow. The tight seal between the disk and seat ensures minimal leakage.
- The design of the globe valve allows for precise flow control. Their throttling capability makes globe valves ideal for applications where fine control of flow is necessary.
- Globe valves are usually installed so that the fluid pressure helps to keep the disk tightly against the seat when the valve is closed, improving the sealing capability.
What is the difference between Globe Valves and Gate Valves?
Globe valves and gate valves are different mainly in their design and function. Globe valves are designed for regulating flow, which makes them ideal for applications which requires precise control. The flow path within a globe valve involves a movable disk that can be positioned incrementally to throttle the flow, which provides fine control over the fluid rate. This design, however, creates a tortuous path that results in a higher pressure drop compared to gate valves. Additionally, globe valves can achieve a tight seal when closed, minimizing leakage, and they operate relatively quickly, needing fewer turns to open or close.
Gate valves, on the other hand, are usually used for on/off control. They have a gate-like disk that moves vertically to open or close the valve, which provides an unobstructed, straight-through flow path when fully open. This results in a very low pressure drop, making gate valves suitable for applications where maintaining flow efficiency is crucial. However, gate valves are not suitable for throttling purposes because partially opening them can cause vibration, noise, and potential damage. They also require more turns to operate fully, making them slower to open or close compared to globe valves. Gate valves are typically less expensive and better for applications where the valve remains in either a fully open or fully closed position for extended periods.
