Banjo ® Polypropylene Check Valves These polypropylene check valves have a one piece construction. • Glass filled polypropylene • One piece construction • EPDM gasket • 316 stainless steel spring 5 1 30977 Nibco ® Chemtrol ® True Union Red Kynar ® Ball Check Valves These check valves stop the flow of media in one direction while allowing flow in the opposite direction, all with minimum turbulence and chatter (and while maintaining pump prime). The valve's injection-molded polyvinylidene fluoride (PVDF) construction is ideal for use with hot corrosive liquids, chemical processing, industrial plating, waste treatment systems, and outdoor installations. The original Chemtrol ® True Union design allows the valve and operational components to be conveniently lifted from the piping system for repair or replacement. Chemtrol ® Kynar ® red PVDF exhibits superior strength, working temperature, and chemical resistance characteristics. It has versatile chemical resistance to slats, strong acids, dilute bases, and many organic solvents such as aromatics, aliphatics, and chlorinated groups. PVDF is also ideally suited for handling wet or dry chlorine bromine and other halogens. • Red Kynar ® • FKM O-ring • Valve pressure rating: 150 psi at 73°F water non-shock • Maximum service temperature: 280°F • Red pigment provides UV protection • ASTM D3222 Type I material • Do not use or test with compressed air or other gases Price $339.44 $463.70 $636.66 $1,131.40 $1,415.25 Prices are subject to change.
