It is constructed from hardened alloy steel with a 316L stainless steel seat, rated for pressures up to 10 MPa and temperatures up to 350°C. The valve operates under cyclic conditions, handling abrasive coal dust at flow rates of 15 - 40 kg/s.
The valve body is cast using lost-wax precision casting with post-weld stress relief and surface hardening to resist erosion from coal particulates. Internal components are coated with tungsten carbide to extend service life in high-wear environments. This design aligns with API 6A and ISO 10434 standards for coal handling valves in power generation. It is not intended for steam or gas service outside coal feed applications.
This valve is purchased by power plant operators in Asia, Eastern Europe, and Southeast Asia for retrofitting existing coal-fired boilers. It is supplied with a flanged connection per ASME B16.5 Class 600, and mounting dimensions follow standard OEM templates. Packaging includes anti-corrosion oil coating, foam padding, and wooden crate. Lead time is not stated; buyers must confirm production scheduling with the supplier.

Before ordering, verify the valve’s material certifications, including MTRs for the body and seat, and pressure test reports per API 6A. Confirm the coating thickness and hardness with a certified lab report. Do not accept valves without traceable batch numbers or test documentation. Ensure the valve matches your existing piping flange class and bolt pattern.
Logistics are typically FOB Qingdao or Shanghai port. Lead time is 6 - 10 weeks from order confirmation, depending on production scheduling. Payment terms are commonly 30% advance, 70% against shipping documents. Incoterms should be FOB or CIF. Confirm containerization details and export packaging to prevent corrosion during sea transit.
Upon delivery, inspect for surface damage, flange warping, or seal degradation. Perform a visual check of the tungsten carbide coating for cracks or peeling. Conduct a hydrostatic test at 1.5x rated pressure before installation. Retain a sample valve for reference and request a 12-month warranty covering wear-related failure.
