API stands for American Petroleum Institute. API Globes valves are designed, manufactured and tested as per API standards.
SVR Global is a trust-worthy API Globe Valve Manufacturer in USA that offers a wide range of API Globe Valves that are tailored to specific industrial demands. Our designs are specially made to give a high degree of reliability, sustainability, durability, and the highest standards in the entire production process.
Definition of a Globe Valve:
A globe valve is most commonly used in systems to open, close or throttle flow.
It is named after its globular body. A globe valve has two halves of the body being separated by an internal baffle. It has a disc (ball, composition or plug) attached to a stem that swings up and down to control flow and a seat. The flow line is either parallel to or inclined towards the seats. It stops the flow of fluid by moving the disc against the flow stream.
A globe valve is bi-directional, meaning the fluid can flow in either direction within the valve. It can be used both manually as well as automatically.
Applications of an API Globe Valve:
- Applications for Steam
- Feedwater, condenser air, chemical feed
- Found in extraction drains and condensing air extraction systems
- Fuel oil system
- Piping in small sizes
- Plumbing sector.
- Pumps and compressors.
- Suitable for systems requiring frequent stroking, vacuum, or a wide variety of temperature extremes.
- Used as an Emergency shutdown valve
- Used in low-point drains and high-point vents
- Used in systems where flow control is required
- Used in systems where leak tightness is important
- Used in systems where pressure drop is not an issue
- Water-cooling systems.
Advantages of an API Globe Valve:
- The ability to turn off the device is excellent.
- Cleaning and resurfacing the chairs is a breeze.
- The disc can be used as a stop-check valve if it is not connected to the stem.
- Pressure Bonnet of Seals
- Stroke lengthening
- A stem that does not rotate
- Throttling skill that ranges from good to exceptional
Industries that use API Globe Valve:
- Electric power industry
- Textile industry
- Petroleum industry
- Sewage
- Construction
- Oil and gas
- Boilers
- Steam
- Pulp and paper
Types of a Globe Valve:
API Globe Valve
The two sides of a globe valve are unscrewed to open and close the valve. It is most commonly used in systems to open, close, or throttle flow. A globe valve has a stem that swings up and down to control flow, as well as a disc (ball, composition, or plug) and a seat that are both linked to the valve body. The flow line is either parallel to or inclined towards the seats. A globe valve is bi-directional, meaning the fluid can flow in either direction within the valve. It allows you to control the flow and pressure as well as full cut off the flow. It can be used both manually as well as automatically.
Bellow Seal Globe Valve
A Bellow Seal Globe Valve is a control valve with a compact structure that uses bellow to seal the valve stem components. The bellow valve has a bellow within, and the stainless-steel bellows' lower end is welded to the stem to keep the system fluid from eroding it. To produce a permanent seal, the other end is positioned between the body of the valve and the cover of the valve. This double seal construction prevents leakage, as the stem packaging will prevent additional leakage even if the bellows collapse. The bellows are welded to the valve stem to guarantee consistent working efficiency and to avoid valve stem vibration caused by valve insert movement.
Forged Steel Globe Valve
Forged steel is a material created by fusing iron and carbon under extreme pressure. Forged steel has lower surface porosity, a finer grain structure, stronger tensile and fatigue strength, and more ductility than other treated steels. Steel becomes ductile and malleable when heated to forging temperature, allowing it to be shaped into the required shape with force and pressure.
Forged valves are created using a process known as forging, which involves shaping metals & alloys while they are still solid. Forged valves are known for their strength, making them excellent for high-pressure and high-temperature applications.
