从China供应商批量进口A300 Series Slow-Closure Type Check Valve

The A300 Series is a slow-closure type check valve with a diaphragm design that eliminates friction during operation, providing a quick response to pressure changes. It features an adjustable closing time to mitigate water hammer effects and reduce noise, making it suitable for systems where fluid flow reversal must be controlled gently. The valve operates automatically without external power, using a single combined disc for simplified maintenance.

This model complies with BS EN 1092-2 for flange standards and EN 558 Series 10 for face-to-face dimensions, ensuring compatibility with European piping systems. The nominal diameter ranges from DN50 to DN400 (2" to 16"), with a pressure rating of PN 16 and a temperature range of -5°C to +85°C. The body is typically constructed from ductile iron or carbon steel, with EPDM or NBR seals for water and ethylene glycol applications.

Industries such as water treatment, HVAC, and chemical processing use this valve to protect pumps and pipelines from damage caused by sudden flow reversal. Buyers should confirm the exact material composition, as the listing does not specify the body or seal materials. Trade terms, including MOQ, packaging, and Incoterms, are not provided and must be discussed directly with Zhejiang Banninger Fluild Control Co., Ltd.

Zhejiang Banninger Fluild Control Co., Ltd. is based at No. 555 Zonglv Road, Bridge District, Haiyan County, Jiaxing, Zhejiang Province, China. The location places the company in a region known for fluid control equipment manufacturing, with access to raw materials and export infrastructure via nearby ports like Ningbo and Shanghai.

The supplier holds a harbor trust tier, confirming a verified operational presence, but no response rate or average response time is available. The profile does not include details such as years in operation, production capacity, or certifications, so buyers should request these directly to evaluate the supplier’s technical capabilities and reliability.
