They are a fully passive flow device requiring neither maintenance nor any outside sources of power or manual assistance to operate.

The Check valves are offered as direct replacements for ineffective and maintenance ridden flap type check valves, commonly known to seize, rust and bind in unwanted positions. Unlike flap type valves, the  rubber check valve will handle large obstructions without jamming or having swing gates binding open.rubber check valves to provide backflow protection from

1.sewage slurries,

2.outfalls to ocean fronts from heavy rainfall activity,

3.prevention from land erosion due to back flow conditions,

4.protection from saltwater to fresh water ponds and catch basins and numerous other water based applications. our history in the manufacture of rubber piping products dates back to 1986. When an engineered solution is needed to solve a piping or backflow problem.

Yu-xiang®Rubber Check Valve are available in a Flanged:

Designed to bolt directly to existing flanges or new installations, flanges are drilled 150# standard. Other drilling standards are also available upon request. can be installed in either vertical or horizontal application.

Yu-xiang® Rubber Check Valves are available in a various selection of elastomers including NSF/ANSI 61 certified material and back pressure capabilities to suit most applications.

Rubber Check Valves will not freeze or deform and functions solely on the inlet and back pressure which will be present in each application.

Each valve is carefully constructed using the finest of engineered materials and some of the most experienced rubber technicians in the industry. All check valves are engineered in precise detail to ensure proper operation and will provide years of unhindered operation and trouble free service.

Benefits of the Rubber Check Valves:

• All rubber construction resists abrasive slurries

• NSF61 is standard construction

• Very quiet operation with no water hammer

• Its unique design prevents backflow

• Negligible maintenance and energy costs

• Will not warp or freeze

• Quick interchange with any flap type check valve

• Available in sizes 1" – 96"

• Available with special I.D to suit concrete pipe
