Practical knowledge of the valve: globe valve classification and characteristics
There are several common types of globe valves, each designed for specific applications and flow control needs. First, the straight-through globe valve is one of the most basic and widely used designs. It allows fluid to pass through in a straight line, making it simple and effective for general use.
Another type is the DC (Direct Current) or Y-type globe valve. In this design, the flow path inside the valve body is angled relative to the main flow direction. This unique configuration reduces turbulence and minimizes the disruption of the fluid flow, resulting in lower pressure loss compared to standard globe valves. As a result, it's often preferred in systems where minimizing energy loss is important.
The angle stop valve is another variation, where the fluid changes direction only once as it passes through the valve. This single-direction change leads to less resistance and a smaller pressure drop than traditional globe valves, making it suitable for applications where space is limited or flow efficiency is key.
Lastly, the plunger globe valve is a specialized version of the conventional globe valve. Instead of a flat disc, it uses a plunger that moves up and down along the stem. The sealing mechanism relies on two elastic rings that are positioned around the plunger. A collar separates these seals, and the entire assembly is compressed by the bonnet nut, which applies pressure to ensure a tight seal. These elastomeric seals are interchangeable and can be made from various materials, allowing for flexibility in different operating conditions.
Although globe valves are primarily used for "on" or "off" functions, certain configurations—such as modified plungers or special collars—can also allow for flow regulation. This makes them versatile for both shut-off and throttling applications. Overall, each type of globe valve offers distinct advantages depending on the system requirements, flow characteristics, and maintenance considerations.
