Nil-Cor Threaded Ball Valves

This special purpose ball valve is available in ½", ¾", 1", 1½" and 2" sizes for corrosive chemical service in pressure piping systems. It is available in both Nil-Cor 510 (glass fibre reinforced PPS resin) and Nil-Cor 410 (glass fibre-reinforced polysulfone resin). Short term exposure to 300°F is acceptable. Exposure above 325°F should be avoided.

Valves have standard NPT ½", ¾", 1", 1½" and 2" end connections. Valve sizes ½", ¾" and 1" have regular port one inch balls in the center body section. The 1½"and 2" valves are regular port. The three-piece design permits assembly to replace all parts without machining or bonding or unthreading pipe connections.

Materials of Construction:
The 410 and 510 Threaded-End Ball Valves are geometrically identical, but made with different resins. The 4l0 and 5l0 body, end caps, ball and Hastelloy "C" stem insert are molded in either the 410 or the 510 composite material. Both valves share the same graphite fibre-reinforced TFE stem thrust washer, self-relieving virgin TFE seats, Viton(R) stem and body O-rings, composite T-handle, and 300 series stainless steel body bolts, nuts and washers.
