Import Bellows Valves Wj15f2.5p — Buy in wholesale FOB from Supplier in China

The WJ15F2.5P is a bellows-sealed globe valve designed for high-pressure steam and gas applications in power generation and industrial systems. It features a stainless steel bellows assembly that prevents stem leakage, a critical requirement in thermal power plants and metallurgical operations where media purity and zero emission are non-negotiable. The valve is rated for a working pressure of 2.5 MPa, with a nominal diameter of DN15, and operates reliably in temperatures up to 425°C, making it suitable for superheated steam lines and auxiliary systems in turbines and boilers.

Constructed from forged carbon steel or stainless steel, the WJ15F2.5P incorporates a precision-machined disc and seat for tight shutoff, with a typical hardness of HRC 35-45 for the trim components to resist wear. The bellows material is commonly Inconel 625 or AISI 316L, offering typical corrosion resistance to chloride and sulfide environments as well as fatigue life exceeding 10,000 cycles under standard ASME B16.34 conditions. Variations may include extended bonnet designs for high-temperature isolation or cryogenic service, though this model is optimized for standard steam service.

This valve is primarily sourced by EPC contractors and MRO teams in power stations, where it is installed in feedwater systems, drain lines, and bypass circuits. Dongfang Yoyik Engnieering supplies it as part of a broader portfolio of power plant spares, including pressure reducing valves and solenoid actuators, with packaging typically involving wooden crates for export. Buyers should confirm compatibility with existing pipeline materials and flanges, as the WJ15F2.5P uses a typical ANSI B16.5 Class 300 flange connection.

Dongfang Yoyik Engnieering Co., Ltd. is based in Deyang, Sichuan Province, China, with its office and technical team located at 4-3F, Building A, Huashan Platz. The company has specialized in the manufacture and supply of industrial spare parts since 1989, building a reputation for technical expertise in power plant and metallurgical applications. Its product range extends beyond valves to include generator set accessories, electromagnetic valves, and customized components for thermal and hydropower stations.

The supplier’s focus is on providing professional support for technical transformations and overhaul projects, offering not just off-the-shelf parts but also tailored solutions for complex engineering challenges. While the company does not disclose specific certifications or client lists in its profile, its long-standing presence in the sector and the breadth of its catalog suggest a capacity to meet stringent industrial standards. Buyers should directly verify compliance with project-specific requirements, such as ASME or PED certifications, as these are not explicitly stated.
