C8000 Ball Valve with Teflon®-fused Ductile Iron Ball

Patent Pending!

Superior Design, Superior Results
Quality Certified Valve Company’s Patent Pending Hardball C8000 Ball Valve conforms to ANSI Standard B16.10, to replace gate and eccentric plug valves. The Hardball C8000 end-to-end and flanged dimensions exactly match cast-iron gate valves and plug valves.

Superior Shut-off
The precision engineering and superior design of the Hardball C8000 features Class 6 bubble-tight positive shutoff. Gate and plug valves, which are known to leak upon installation, achieve only Class 4 non-positive shutoff.

Ball Valve with Teflon fused ductile iron ball

Superior Flow Rate
Full port design of the Hardball C8000 yields 50-75% greater flow rate compared to the flow rate of conventional gate valves.
Example: 6" C8000 Ball Valve flow rate = 5,470 GPM,
6" Gate Valve flow rate = 3,175 GPM.

Superior Seal
The Hardball C8000’s blow-out proof Stainless-Steel stem and Chevron PTFE Teflon Stem-Seal packing eliminates leakage of air, fluids and steam. Plus, the C8000’s reinforced Teflon Seats are not exposed to abrasion or line pressure, unlike the gate’s exposed bronze seat. Gate valves require costly on-going maintenance to limit leakage.

Superior Ratings
QC’s Hardball C8000 is NSF 61-8/California Prop65 approved; AWWA C507-99 Proof of Design Tested, Tested to API 598, with an FDA Food-grade Epoxy coated body. Inferior gate valves cannot meet the rigid testing and Safe Drinking Water Standards of the Hardball C8000.

Superior Quarter Turn Design
The Hardball C8000 can be locked either fully open or closed.With its ISO 5211 Mounting Pad, the C8000 can be easily and cost-effectively actuated, whereas multi-turn gate valves cannot be effectively or affordably automated.

Superior Materials
Quality Certified Valve Company’s Hardball C8000 Ball Valve–constructed with a FDA food-grade epoxy powder coating body–is twice as strong as the competition’s ball.

Superior Strength
Quality Certified’s exclusive, Teflon-fused ductile-iron ball has a tensile strength of 65,000 vs. 31,000 for the competitor’s inferior cast-iron ball (figure 1). The fused Teflon non-stick coating prevents pitting, corrosion, and build-up of calcium, lime and sludge. This significantly increases lubricity while reducing torque and premature failure that normally results.

Superior Performance
QC’s Hardball features superior stem-to-ball engagement, ensuring positive leak-proof
shut-off and control. Traditional cast-iron used
in other ball valves is less than half the tensile strength of ductile. Through normal use, cast-iron balls can wear prematurely, damaging the stem-to-ball engagement and the ball’s ability to rotate (figure 2).
