Import Accumulator Charge Valve 10l For Power Plant — Buy in wholesale FOB from Supplier in China

The 10L accumulator charge valve is a hydraulic control component designed for power plant accumulator systems, specifically engineered to regulate pre-charge pressure and isolate bladder or piston accumulators with a 10-litre nominal gas volume from the main hydraulic circuit. Manufactured by Deyang Dongfang Yoyik Engineering in Sichuan Province, this valve integrates charging port, pressure gauge connection, and shut-off functionality in a single compact body suited for confined turbine auxiliary equipment spaces. The unit serves critical safety functions in emergency shutdown systems and energy storage circuits where rapid discharge and reliable isolation prevent equipment damage in thermal generation facilities.

Construction typically employs forged or cast carbon steel body with hardened alloy steel poppet and seat components to withstand repeated pressure cycling at accumulator operating pressures. Sealing elements depend on system fluid: NBR or HNBR for mineral oil applications, with FKM or PTFE alternatives for phosphate ester (EH) fluid compatibility in modern steam turbine electro-hydraulic control systems. The 10-litre accumulator size corresponds to medium-capacity energy storage for turbine governing systems, boiler feed pump emergency lubrication, or valve actuator backup power, standard configurations in 125 MW to 600 MW unit auxiliary systems across Chinese and export installations.

Target buyers include power plant maintenance departments, turbine overhaul contractors, and hydraulic system integrators replacing worn charge valves during scheduled outages. The valve interfaces with standard charging kits and pressure test equipment used in accumulator maintenance protocols. Deyang Dongfang Yoyik Engineering markets this component alongside broader power plant spare part ranges including servo valves, oil pumps, and sealing components, suggesting integrated sourcing opportunities for complete auxiliary system refurbishment. Confirm specific port configurations, pressure ratings, and certification package scope before procurement, as the source description does not detail these parameters.

Deyang Dongfang Yoyik Engineering Co., Ltd. maintains its headquarters at Huashan Plaza, Jingyang District, Deyang City, Sichuan Province, China, postal code 618000, the same address as its sister listing for accumulator charge adapters. The company holds harbour-tier platform status with zero recorded response rate and zero average response hours, indicating no recent transactional activity or enquiry handling data is visible through this channel. The supplier profile emphasises advanced production equipment including CNC lathes and machining centres, alongside a claimed strict quality management system, though no specific certification body or standard is named.

The company positions itself as a manufacturer of power plant spare parts with application coverage from turbines to coal-fired generators, citing participation in key domestic and international engineering projects without naming specific clients, locations, or contract values. The listing for this 10L accumulator charge valve presents it within a broader product range including servo valves, oil pumps, mechanical seals, and sealing components. No information is provided regarding factory floor space, employee count, annual revenue, R&D investment, or patent holdings. Buyers should conduct independent due diligence including factory audit, quality system verification, and reference checks with existing power sector customers before committing to volume orders.
