A globe valve refers to a valve in which the closing element (valve disc) moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the stroke of the valve disc.

Due to the relatively short opening or closing stroke of the valve stem and its highly reliable shut-off function, as well as the proportional relationship between the change in the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow. Therefore, this type of valve is very suitable for use as a cut-off, regulating, and throttling device.

The selection principle is: 1. Globe valves should be used on pipelines or devices for high temperature and high pressure media. High temperature and high-pressure pipelines in thermal power plants, nuclear power plants, and petrochemical systems. 2. On pipelines with lax flow resistance requirements. Places where pressure loss is not given much consideration. 3. Small valves can be selected from needle valves, instrument valves, sampling valves, pressure gauge valves, etc. 4. There is flow regulation or pressure regulation, but the requirement for regulation accuracy is not high, and the pipeline diameter is relatively small, such as on pipelines with nominal diameter ≤ 50mm, it is recommended to choose. 5. Small and large fertilizers in synthetic industry production should use high-pressure angle globe valves or high-pressure angle throttling valves with nominal pressure PN160 and nominal pressure 16MPa or PN320 and nominal pressure 32MPa. 6. In the desilication workshop and coking prone pipelines of alumina Bayer process production, it is easy to choose DC globe valves or DC throttling valves with separate valve bodies, removable valve seats, and hard alloy sealing pairs. 7. For water supply and heating projects in urban construction, shut-off valves, balance valves, or plunger valves can be used for pipelines with a nominal diameter of less than 150mm.

Pay attention to the issue of the valve being in the on/off position when forging steel globe valves. Ball valves are usually maintained in the open position, and in special circumstances, they may be closed for maintenance. Other valves cannot be treated solely based on their open position. The forged steel globe valve must be in the closed state during maintenance to ensure that the lubricating grease fills the sealing groove along the sealing ring. If it is in the open position, the sealing grease will directly fall into the flow channel or valve chamber, causing waste. When valve grease is injected, the issue of grease injection effect is often overlooked. The pressure, grease injection amount, and switch position are all normal during the grease injection operation. But to ensure the lubrication effect of the valve, it is sometimes necessary to open or close the valve and check the lubrication effect to confirm that the surface of the valve ball or gate is lubricated evenly.
