API 602 Standard Class 150 Bellow Sealed A105 Forged Gate Valve
Product introduction:
Forged steel gate valve is composed of components such as valve body, valve cover, valve stem, gate plate, and sealing parts. Among them, the valve body and valve cover are made of high-quality forged steel, which has high strength and good corrosion resistance. The valve stem is made of stainless steel material, which has good corrosion resistance and wear resistance. The gate is a key component of the valve, and its sealing performance directly affects the effectiveness of the valve. The sealing structure of forged steel gate valves is usually metal sealed, which can effectively prevent medium leakage.
Bellow sealed forged steel gate valve with another key component is the metal bellow pipe. The lower end of bellow pipe is automatically welded with the valve stem assembly, and the upper end of it is automatically welded with the connecting plate to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem. This special dual sealing design (bellows+packing) to ensure zero leakage, If the bellows fails, the valve stem packing will also avoid leakage and comply with international sealing standards.The valve cover comes with a grease fitting, which can directly lubricate the valve stem, nut, and shaft sleeve, good performance than the traditional gate valves which can only add lubricating oil to the threads.

Product features:
1. Good sealing performance: The forged steel corrugated pipe gate valve adopts corrugated pipes as the sealing structure, which can achieve zero leakage sealing effect, and is very suitable for industrial occasions with strict requirements.
2. Long service life: The corrugated pipe is made of high-quality stainless steel or high-temperature alloy materials, which have excellent corrosion resistance and fatigue resistance, and the service life can reach more than 10 years.
3. Compact structure: Compared with traditional gate valves, forged steel corrugated pipe gate valves have small volume, light weight, convenient installation, and are suitable for situations with limited space.
4. Flexible operation: The operation methods of forged steel corrugated pipe gate valves are flexible and diverse, and can be controlled manually, electrically, hydraulically, and other ways to meet various industrial application needs.
