Import Bellows Valves Khwj20f1.6p — Buy in wholesale FOB from Supplier in China

The KHWJ20F1.6P is a bellows-sealed globe valve designed for high-integrity isolation in power plant auxiliary systems. This model incorporates a 1.6 MPa pressure rating with a DN20 nominal diameter, using a metal bellows to prevent stem leakage, a critical requirement in steam and gas applications. The valve body is typically cast from carbon steel or stainless steel, depending on the medium, with a flanged end connection for secure piping integration.

Bellows valves of this series are engineered with a convoluted metal bellows assembly that compensates for axial movement, ensuring zero leakage across the stem interface. The standard material for the bellows is AISI 316L stainless steel, offering corrosion resistance in high-temperature steam environments. The valve disc and seat are often stellite-hardfaced for extended service life, while the stem is protected by a graphite-packed gland as a secondary seal. Typical industry standards for such valves include ASME B16.34 for construction and API 598 for pressure testing.

These valves are primarily deployed in thermal and nuclear power plants for applications such as turbine gland steam systems, heater drain lines, and auxiliary steam isolation. Buyers typically include EPC contractors, power plant operators, and OEMs sourcing components for new builds or maintenance projects. The valve’s compact design and reliable sealing make it suitable for systems requiring frequent cycling. Confirm the exact material composition, pressure-temperature ratings, and compliance with project-specific codes like ASME Section III for nuclear service before ordering.

Dongfang Yoyik Engnieering Co., Ltd. is based in Deyang, Sichuan Province, China, with its office and technical center located at 4-3F, Building A, Huashan Platz. The company specializes in machinery and industrial equipment for power generation, including a broad catalog of spare parts for thermal, hydroelectric, and coal-fired plants. Its product portfolio spans sensors, transmitters, switches, and valves, with a focus on components for steam turbines, boilers, and auxiliary systems.

The supplier’s profile highlights a technical research and development team alongside a mature after-sales service structure, supporting customers with installation guidance and troubleshooting. While the listed response rate is currently zero, the company positions itself as a provider of precision-engineered parts for critical power industry applications. Buyers should verify the supplier’s current response protocols and technical support availability directly for time-sensitive projects.
