What is a Globe Valve?
SVR Global is the biggest Globe valve manufacturer in the USA. A globe valve is a type of flow control valve. It has a spherical body with a moveable disc and a ring seat. It is employed for the purpose of throttling. It has a valve seat that is parallel to the flow line. The valve's design forces the liquid to flow in a different direction within itself. These valves can be operated manually or automatically. Globe valves can be used to control the flow of pressure as well as cut off the flow completely. When compared to other valves, the Globe valve has a higher pressure loss when fully opened. The disc can either entirely withdraw itself from the liquid's flow route or completely close it. This is a type of valve in which the closing component (disc) rotates along the valve seat's centerline. The valve has a very dependable cut-off function since the opening or shutting stroke of the valve stem is relatively short, and the change in valve seat opening is proportionate to the stroke of the disc, making it ideal for flow regulation. As a result, this sort of valve is suitable for throttling and switching off or regulating the medium.
What are the types of Globe Valves?
SVR Global is one of the best Bellow Sealed Globe valve manufacturers with strong customer support. The compact structure of a Bellow Sealed Globe valve is utilized to balance the pressure. The Valve is constructed with bellows rather than stuffing boxes, as is the case with all other valves. Because the valve is entirely closed, the seal prevents leaking. The bellow seal Globe Valve is designed for use in pipelines carrying steam, flammable, explosive, or hazardous media. This sort of valve does not require a flow rate that is fully open or fully closed. Even if the bellows are broken, this valve may resist leaking due to valve system packing because of its structure.
The main benefit of the Bellow Sealed Globe Valve is that it prevents fluid loss, which improves the security of the equipment in which it is employed. This valve has a long operational life and requires little maintenance. We are primarily concerned with achieving complete customer loyalty through the provision of high-quality industrial valves.
A globe valve consists of two sides that are unscrewed to open and close the valve. They’re most typically employed to open, close, or throttle flow in systems. Globe valves have a stem that swings up and down to control flow within the valve, as well as a disc (ball, composition, or plug) and a seat that is generally connected to the valve body. The flow line is parallel to or inclined to the seats. For fluid control and throttling, globe valves have long been the industry standard. Globe valves are used to control the flow of a fluid as well as to shut it off. Unlike check valves, globe valves are bi-directional, meaning the fluid can flow in either direction within the valve. Globe valves allow you to adjust flow and pressure as well as shut off the flow completely. These can be utilized both manually and automatically.
Forged steel globe valve is the most common type of valve. It’s so popular because the friction between the sealing surfaces is less during opening and shutting, it’s more durable, and the opening height isn’t excessive. Forged steel globe valves can handle medium and low pressures, as well as high pressures. Its closing concept is that the sealing surface of the disc and the sealing surface of the valve seat are closely attached to prevent the medium from flowing by depending on the pressure of the stem. The media can only flow in one direction through the forged steel globe valve, which is directed during installation.
The forging steel globe valve has a longer construction than the forged steel gate valve, but the fluid resistance is higher and the seal dependability is lower when used for a long time. For industrial applications, forged steel globe valves are fabricated to API, ANSI, and ASME standards.
Compact and durable, forged steel globe valves are suited for high-pressure and high-temperature applications.

What are the Advantages of a Globe Valve?
- Pressure Seal Bonnet
- Shorter stroke length
- Good shutdown capabilities
- Non-rotating stem
- Moderate to good throttling ability
- The seats are simple to machine or resurface, and they can be utilized as a stop-check valve when the disc is removed.
What are the Disadvantages of a Globe Valve?
• There is a throttling flow under the seat and a shutdown flow above the seat, making seating the valve more difficult or requiring a larger actuator.
• Low-to-moderate pressure limitation
