Import Brass Check Valve With Male Thread End — Buy in wholesale FOB from Supplier in China

This brass check valve with male thread end is a spring-assisted, non-return valve designed to prevent backflow in piping systems carrying water, oil, or gas. Manufactured by Yuhuan Jingyilai Valve Co., Ltd. in Zhejiang Province, China, it is offered in nominal sizes from 1/2 inch to 4 inches (DN15 to DN100), with the specific model JYL-7108 representing the 1/2 inch variant. The valve body is forged from brass, a copper-zinc alloy chosen for its corrosion resistance, machinability, and suitability for medium-pressure applications up to standard working pressures typical of residential and light commercial plumbing.

The valve operates on a spring-loaded disc mechanism: forward flow lifts the disc off its seat against spring resistance; reverse flow or system depressurisation allows the spring and back pressure to reseat the disc, sealing the line. Brass construction (typically CW617N or CW614N grade, though the supplier does not specify) provides compatibility with potable water when lead-free formulations are used, and resists dezincification in aggressive water conditions. Thread ends comply with ISO 228 (BSP parallel) or NPT standards, depending on destination market, with 1/2 inch to 4 inch coverage suggesting both domestic and export configurations. The spring is typically stainless steel 304 or 302, though material grade should be confirmed.

Buyers include plumbing wholesalers, HVAC contractors, industrial fluid handling distributors, and OEMs integrating valves into packaged systems. Applications span residential water supply, heating circulation loops, compressed air lines, and fuel oil transfer where one-way flow protection is required. Importers should confirm pressure-temperature ratings, thread standard, and whether the brass alloy meets local lead-content regulations such as NSF/ANSI 61 or the EU Drinking Water Directive. The supplier lists a harbor trust tier with zero recorded response rate, so direct enquiry to verify current production capacity, sample availability, and exact material certifications is essential before committing to volume orders.

Yuhuan Jingyilai Valve Co., Ltd. is located in Yuhuan County, Taizhou, Zhejiang Province, China, an area recognised as a concentrated manufacturing hub for plumbing valves and fittings. The supplier address places it within the local science and technology industrial zone. The company holds a harbor trust tier on the marketplace, which represents a baseline verification level. The response rate is recorded at zero percent with an average response time of zero hours, indicating either no recent enquiry activity or incomplete platform engagement data. Importers should treat direct communication as the only reliable channel for verifying current operational status and capacity.

The listing focuses on brass valve products for water, oil, and gas applications, with the JYL-7108 model as a specific catalogue item.
