Features
1、High-Performance Forged Body Construction: The valve body is formed through an integral forging process using high-quality carbon steel, stainless steel, or alloy steel. This eliminates casting defects, significantly enhances material density and strength, ensuring long-term stable operation under high pressure, high temperature, and demanding conditions, and completely avoids the risk of pressure-containing part failure.
2、Reliable Automatic Sealing System: The sealing surfaces of the disc and seat feature a metal-to-metal or metal-to-non-metal design. The sealing surfaces are precision ground to ensure excellent mating contact. The valve utilizes the forward pressure of the medium to automatically open the disc. When flow reverses or stops, the disc closes rapidly by its own weight and the reverse pressure, providing tight and reliable unidirectional shut-off to prevent backflow.
3、Compact Female Threaded Connection: It utilizes standard tapered pipe threads (such as NPT, PT, BSPT) or straight threads for connection. The valve screws directly onto the pipe, allowing for quick and easy installation, as well as convenient disassembly and maintenance. The threaded connection is compact and occupies minimal space, making it particularly suitable for piping systems with space constraints.
4、Low Flow Resistance Straight-Through Flow Path Design: The internal flow path features a straight-through design. This results in a short, smooth media flow path, effectively reducing fluid resistance losses and pressure drop. The smooth transitions in the flow path avoid turbulence and media stagnation, making it suitable for various industrial fluids including water, steam, oil, and corrosive media.
5、Wide Applicability Across Operating Conditions: The product design covers pressure classes from Class 800 to Class 2500 and a wide temperature range. It meets the piping control requirements of diverse industries such as petroleum, chemical, power, metallurgy, pharmaceutical, and general industrial applications.
6、Operation and Configuration: As an automatic valve, it requires no external power source or manual operation. It relies entirely on the energy of the flowing medium to open and close, providing sensitive response and reliable action. It can be installed in either horizontal or vertical positions, offering installation flexibility to suit different piping layout requirements.
