Understanding Globe Valves

globe valves are and how they work. Globe valves are linear motion valves that control the flow of fluids by moving a disc (or plug) along a seat, which regulates the flow rate. These valves are used to start, stop, and regulate the flow of liquids, gases, or steam in various applications, including industrial, commercial, and residential systems.

Before diving into the selection process, let's have a basic understanding of whatare and how they work. Globe valves are linear motion valves that control the flow of fluids by moving a disc (or plug) along a seat, which regulates the flow rate. These valves are used to start, stop, and regulate the flow of liquids, gases, or steam in various applications, including industrial, commercial, and residential systems.

Selection Tips and Considerations

1. Application and Fluid Compatibility: One of the first considerations when selecting a globe valve is the application and the type of fluid it will be handling. Different applications require different materials and designs to ensure optimal performance and durability. Consider factors such as the fluid's temperature, pressure, corrosiveness, and viscosity to choose the right materials and valve design. Consult with experienced Globe Valve Manufacturers and Suppliers who can provide guidance on material compatibility.

2. Valve Size and Pressure Rating: The valve size and pressure rating must match your system's requirements. Oversized or undersized globe valves can lead to inefficiencies, increased energy consumption, or even system failures. Refer to industry standards and consult with experts to determine the appropriate valve size and pressure rating for your application.

3. Flow Control: Globe valves are versatile when it comes to flow control. They can be used for on-off service or for throttling and regulating flow. If precise flow control is required, consider selecting a valve with a design optimized for throttling applications. Keep in mind that improper flow control can lead to excessive wear and reduced valve lifespan.

4. Materials of Construction: Globe valves are available in various materials, including stainless steel, brass, bronze, cast iron, and more. The choice of material depends on factors like fluid compatibility, temperature, and corrosion resistance. For example, stainless steel is suitable for corrosive fluids, while bronze is often chosen for seawater applications. Consult with Globe Valve Manufacturers and Suppliers to determine the best material for your needs.

5. Bonnet Type: Globe valves have two common bonnet types: bolted bonnet and pressure seal bonnet. The choice between the two depends on the pressure and temperature requirements of your system. Pressure seal bonnets are suitable for high-pressure applications, while bolted bonnets are generally used for lower-pressure systems.

6. Sealing Mechanism: Globe valves can have different sealing mechanisms, including globe, plug, and needle. The choice of sealing mechanism affects the valve's ability to provide a tight shut-off and control the flow accurately. Consider the level of leakage tolerance acceptable for your application and choose the appropriate sealing mechanism accordingly.

7. Actuation: Globe valves can be operated manually, pneumatically, electrically, or hydraulically. The choice of actuation depends on factors like the valve's size, accessibility, and the need for remote control. For large or hard-to-reach valves, automated actuation systems may be necessary for convenience and efficiency.

8. Maintenance and Accessibility: Globe valves, like all mechanical equipment, require regular maintenance. Consider ease of access for maintenance when selecting a valve. Valves with readily accessible components and spare parts availability can reduce downtime and maintenance costs.

9. Compliance with Standards: Ensure that the selected globe valve complies with relevant industry standards and certifications. Compliance with standards ensures the valve's performance, safety, and reliability in your application.

10. Supplier Reputation: Finally, choose Globe Valve Manufacturers and Suppliers with a strong reputation for quality, reliability, and customer support. A reputable supplier can provide valuable guidance, technical expertise, and after-sales support, ensuring a smooth and successful valve installation.

Conclusion

When it comes to choosing the right globe valve for your fluid control needs, there's no room for compromise. By carefully considering factors such as application compatibility, valve size, materials, and flow control requirements, and working with reputable Globe Valve Manufacturers like Oswal Industries Limited, you can make an informed choice that enhances the performance and longevity of your fluid control system.

Application and Selection Principle of Globe Valve

The globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from under the disc, the resistance that the operating force needs to overcome is the friction force between the valve stem and the packing and the thrust generated by the medium pressure. Since the force to close the valve is greater than the force to open the valve, the diameter of the valve stem should be larger, otherwise there will be a failure of the valve stem bending.

According to the connection method, it can be divided into three types of globe valve: flange connection, threaded connection and welding connection. Since the appearance of the tight sealing valve, the medium flow direction of the globe control valve has changed from the top of the disc to the valve cavity. At this time, under the action of the medium pressure, the diameter of the valve stem can be reduced accordingly because the pressure to close the valve is small and the pressure to open the valve is high. At the same time, under the action of the medium, the valve is also relatively tight.

1. Application of globe valves

Globe valves can be used in heat transfer oil, toxic, flammable, high permeability, polluted environment and radioactive fluid medium pipelines, and can also be used for regulation. All castings for this valve are precision cast. Globe control valve refers to a valve whose closing member (disc) moves along the centerline of the valve seat. According to this movement form of the valve disc, the change of the valve seat opening is proportional to the stroke of the valve disc. The stem of this valve has a relatively short opening or closing process and has a very good interception function. And because the change of the valve seat opening is proportional to the stroke of the valve disc, it is very suitable for regulating the flow. Therefore, this type of valve is ideal for blocking, regulating and throttling, as well as pneumatic valve control ball valves.

2. Selection principle of globe valves

(1) Globe valves should be selected for pipelines or equipment of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high temperature and high pressure pipelines in petrochemical systems, etc.

(2) The flow resistance of stainless steel globe valves requires a loose pipeline, that is, a local area where pressure loss is rarely considered.

(3) Small valves, such as needle valves, instrument valves, sampling valves, pressure gauge valves, etc.

(4) There is flow adjustment or pressure adjustment, but the adjustment accuracy is not high, and the pipe diameter is relatively small.

(5) Water supply and heating projects in urban construction, as well as pipes with a smaller nominal diameter, such as pipes with a nominal diameter of less than 150mm. All of the above can choose globe control valve, balance valve or plunger valve.
