The Check valve H44H-25 is a high-pressure swing check valve engineered for industrial applications, including thermal power, hydropower, and steel sectors. With a nominal pressure rating of PN25 (25 bar), it is designed to handle higher pressure systems compared to the H42W-10P, making it suitable for demanding environments such as main steam or feedwater lines. The valve’s robust construction includes a cast steel body and metal-to-metal seating for enhanced durability in high-temperature and high-pressure conditions.
This model is part of Dongfang Yoyik’s portfolio of power plant components, which includes pressure relief valves, globe valves, and servo valves. The H44H-25’s swing mechanism ensures low resistance to flow in the forward direction while providing reliable backflow prevention. Industry-standard valves in this class often incorporate a lever and counterweight for improved closure speed, though the exact design for this model should be confirmed with the supplier.
Targeted at EPC contractors and maintenance teams in heavy industries, the H44H-25 is used in systems where flow reversal could damage equipment or disrupt operations. Buyers should validate the valve’s compatibility with their pipeline’s pressure, temperature, and medium, as well as the supplier’s ability to provide supporting components like the DFB80-50-240 cast steel globe valve or KJC65-16 servo motor control valve for integrated solutions. Packaging and lead times are negotiable and should be addressed during the inquiry phase.

Dongfang Yoyik Engnieering Co., Ltd., based in Deyang, Sichuan, China, provides technical solutions and spare parts for power generation and industrial sectors. The company’s expertise spans thermal power, hydropower, and steel industries, offering a comprehensive range of services from equipment selection to installation, commissioning, and after-sales support. Their multi-brand agency status ensures the supply of authentic components for diverse customer needs.
The supplier’s product range includes the H44H-25 check valve alongside other critical components like pressure relief valves, centrifugal pumps, and hydraulic systems. However, their profile lacks specific details on response rates or third-party verifications, so buyers should directly confirm the company’s reliability, lead times, and ability to provide technical documentation for the H44H-25.

Prior to ordering the Check valve H44H-25, confirm the exact pressure and temperature ratings for your system, as PN25 valves are designed for high-pressure environments. Request material certificates for the cast steel body and metal seating to ensure compliance with ASTM or EN standards, and verify the valve’s suitability for your specific medium (e.g., superheated steam).
Discuss the flange standard (ANSI or DIN) and dimensions to ensure a precise fit with your pipeline, and clarify packaging requirements for export, which may include reinforced crates for heavy components. Lead times for the H44H-25 may be longer due to its high-pressure classification, so confirm production schedules and the nearest port (e.g., Shanghai) for FOB or CFR Incoterms.
Upon delivery, inspect the valve for dimensional accuracy and material conformance, and perform a hydrostatic pressure test to validate its rating. Request a test report for the body and seating materials, and consider a third-party inspection for critical applications. Ensure all documentation, including certificates of origin and conformity, is provided to facilitate customs clearance and quality assurance.
