Features
1、High-Performance Forged Body Construction: The valve body is formed through an integral forging process using high-quality forged steel, forged stainless 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 Stem Sealing and Operation System: The sealing surfaces of the disc and seat feature a metal-to-metal hard sealing design. The sealing surfaces are precision ground to ensure excellent mating contact. Rotating the handwheel drives the stem, which lifts or lowers the disc to achieve reliable media shut-off or flow initiation. A multi-layer packing seal structure is employed in the stem stuffing box. The packing gland can be adjusted or the packing replaced as needed, effectively preventing external leakage along the stem.
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 150 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、Manual Operation and Shut-off Characteristics: Operated by a handwheel (counter-clockwise to open, clockwise to close), it features low operating torque, a short travel stroke, and simple, effortless operation. It is suitable for applications involving frequent operation. The stem threads are precision-machined and coated with a lubricating layer to ensure smooth and flexible operation.
