Forged Steel Globe Valve
A Forged Steel Globe Valve is a type of valve where the closure element (valve disc) moves along the centerline of the seat. The movement of the disc directly correlates with the change in the valve seat's port size, making the port adjustment proportional to the disc's stroke. These valves feature a short stem stroke for opening or closing, ensuring reliable shut-off performance and a precise relationship between the seat port and disc movement. As a result, they are highly suitable for applications requiring shut-off, regulation, or throttling.
One of the key advantages of forged steel globe valves is their wear resistance during operation. The friction between the valve disc and the body's sealing surface is minimal compared to gate valves, reducing wear. The open height of the valve is typically only 1/4 of the seat channel's diameter, making it significantly more compact than gate valves. Additionally, the design involves a single sealing surface between the body and disc, simplifying manufacturing and making maintenance easier.
These valves are versatile and can operate in a temperature range of -196°C to 700°C. They are available in various operation modes, including manual, bevel gear, pneumatic, electric, hydraulic, pneumatic-hydraulic linkage, and electro-hydraulic linkage. The body materials include WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M, and Ti (316L), allowing compatibility with a wide range of media such as water, steam, oil, nitric acid, acetic acid, oxidizing agents, urea, and more.
The Bolted Bonnet Forged Steel Globe Valve is a robust and versatile valve designed for high-pressure systems. Its bolted bonnet connection offers ease of use and exceptional strength, making it capable of withstanding significant pressure. However, due to the risk of bolt creep and potential leakage at elevated temperatures, these valves are recommended for applications with operating temperatures of ≤350°C.
