Cast Steel Bellow Seal Globe Valve

Introduction

Cast Steel Bellow Seal Globe Valve is a stop valve that uses a bellows structure as a sealing element, and the valve body material is cast steel. Its main feature is that it can achieve no external leakage and is suitable for working conditions with high requirements for sealing performance. This valve is widely used in industries such as petroleum, chemical, electric power, and medicine, and is especially suitable for systems that require "zero leakage" or extremely high requirements for sealing performance.

 

Advantages

1. Reliable sealing performance
The valve adopts a bellows sealing structure and is designed according to the MSS SP117 standard. The bellows, as a sealing element, can effectively isolate the contact between the medium and the external environment and prevent leakage at the valve stem. This structure is particularly suitable for occasions where toxic, flammable, volatile or highly corrosive media are transported, which helps to ensure the safe operation of the equipment and meet environmental protection and process safety requirements.

 

2. Wide range of applications
The products cover a variety of specifications from 1/2" to 20" (DN15-DN500), suitable for different pipe diameter systems, and meet the use requirements from small pipelines to large industrial devices. The pressure level supports PN10 to PN40 and 150Lb to 600Lb, which can be used in low-pressure to medium- and high-pressure systems and adapt to various working conditions. In addition, the valve design refers to the ASME B16.34 temperature standard, maintains a stable operating state within the allowable temperature range, and meets the use conditions of different industries.

 

3. Comply with the international standard system
The cast steel bellows sealed stop valve is strictly implemented in accordance with international standards in terms of design, manufacturing, connection, testing, etc. Design standards include BS1873, API602, and DIN3356, length standards include ASME B16.10 and DIN3202, connection end standards include ASME B16.5 and DIN2543-2545, butt welding connection refers to ASME B16.25, and inspection standards use API598 and DIN3230.

 

4. Various connection forms
The valve provides a variety of connection methods, including flange connection and butt welding connection, which can meet the requirements of different pipeline systems and installation methods. Flange connection is manufactured in accordance with the American ASME B16.5 and European DIN2543-2545 standards, suitable for quick disassembly and maintenance; while butt welding connection is based on ASME B16.25 and can be used in occasions with higher requirements for sealing and pressure bearing performance.
