Description

Technical Parameters

Forged steel globe valve The globe valve is widely acknowledged as the most commonly used valve in various industries. It has gained immense popularity primarily due to its ability to reduce friction between the sealing surfaces while opening and closing, as well as its lower opening height. Additionally, its convenient manufacturing process and easy maintenance make it a preferred choice among users.
The forged steel globe valve is exceptionally versatile as it is suitable for both medium and low pressure applications, and even for high-pressure situations. Its closure mechanism is based on the concept that, depending on the valve stem's pressure, the sealing surface of the disc and seat come together tightly to prevent the passage of media circulation.

The forged steel globe valve is a unidirectional flow valve that requires correct installation. Compared to the forged steel gate valve, the face to face length of the forged steel globe valve is longer. However, it may experience high fluid resistance and lower sealing reliability when used for extended periods. Generally, the forged steel globe valve is suitable for high-pressure and high-temperature industrial applications. It is essential to consider the features of the valve before using it.

 

Standard compliance

 

ASME B16.34, API602, and BS5352 are the industry standards utilized for the design and manufacture of various products. These standards provide specific guidelines and requirements for different aspects of the manufacturing process. By complying with these standards, manufacturers can ensure the quality, reliability, and safety of their products.
ASME B16.34 is a standard published by the American Society of Mechanical Engineers (ASME) that focuses on the design, materials, and testing requirements for valves, flanges, fittings, and other pipeline components. It provides specifications for pressure-temperature ratings, dimensions, and methods for testing and inspection.
API602, on the other hand, is a standard developed by the American Petroleum Institute (API) for forged steel valves used in petroleum and natural gas industries. It covers the design, materials, manufacturing, testing, inspection, and documentation requirements for these valves.
BS5352 is a British standard that provides guidelines for the design, construction, and testing of small forged steel valves. It specifies requirements for dimensions, pressure-temperature ratings, materials, testing, and marking of these valves.
Designing and manufacturing products in accordance with these standards ensures that they meet the necessary quality and safety criteria. By following the guidelines outlined in ASME B16.34, API602, and BS5352, manufacturers can create products that fulfill industry requirements and satisfy customer expectations.

2. Connection: Socket weld end : ANSI B16.11

The screwed end of a component is typically defined by its thread type, which is often specified using the ANSI B1.20.1 standard. This standard includes both NPT and BSPT thread types, each of which has its own set of specifications and requirements. When selecting a screwed end for a particular application, it is important to carefully consider the thread type and ensure that it is compatible with other components in the system.

4.Test and inspection: API598

·Diameter: 1/4” to 2”

·Class: 800LB,1500LB,2500LB

Our forged steel globe valve range offers both threaded (NPT, BSPT) and socket weld options, with the choice of a bolted or welded bonnet and a pressure seal bonnet. These valves feature an outside screw and yoke design, and can be ordered with either a reduce bore or full bore. The stem is available as both rising and non-rising, and the hand wheel is non-rising. Screwed end or Socket Weld end options are also available.

When it comes to the material used for the body and bonnet of valves, there are a few popular options to choose from. These include forged carbon steel, forged stainless steel, and forged alloy steel. You may have heard of some specific types of steel, such as ASTM A105, A350 LF2, A182 F304, A182 F304L, A182 F316, A182 F316L, F904L, A182 F11, F22, F51, and F53. All of these materials offer different properties and advantages, so it's important to consider your specific needs when choosing the right material for your valve. Whether you need strength, durability, or resistance to corrosion, there's a material out there that can meet your requirements.

The material options available for trim include A182 F6A with stellite sealing for both trim 8 and trim 5, as well as A276 410, 304, 304L, 316, and 316L. These materials offer a range of properties and advantages, such as increased durability and resistance to corrosion, depending on the specific needs of the application. Careful consideration should be given to selecting the most appropriate trim material to ensure optimal performance and longevity.
