JIS FC200 Check Valve

A JIS FC200 check valve is an automatic, self-operating non-return valve cast from Grade FC200 gray cast iron in strict accordance with Japanese Industrial Standards (JIS). Designed to prevent fluid backflow in low-to-medium-pressure water and steam systems, it is commonly manufactured in swing or lift check configurations, utilizing the forward momentum of the fluid to open and gravity or backpressure to close tightly against its seat. Conforming to standards like JIS B2031, JIS B2011, and JIS B2239 (for flange dimensions), these standardized valves are primary specifications in Japanese-built commercial marine vessels, high-rise plumbing, and industrial utility loops, allowing maritime contractors and utility managers to secure seamless backflow containment by importing certified JIS FC200 check valves directly from leading manufacturers in China via our advanced B2B commercial platform.
