American Valve's Model 4000 Cast Iron Flanged-End Ball Valve, revolutionized the PVF industry. With the addition of Model 4000D in Ductile Iron and Model 4001 in 316 Stainless Steel, we are raising the standards for ball valve technology.

The 4000 Series features a Teflon-fused ball that is more durable, less susceptible to accumulating buildup, and is longer lasting than an ordinary unprotected ball. This adds to a long list of advantages over other types of valves.

With the help of Dupont, we developed a process to impregnate Teflon^® .008" into a solid metal ball. An additional .004" is added electrostatically for smoothness. Since the Teflon^® becomes part of the metal, it can't flake, chip, or peel off.

The corrosion and chemical resistance of Teflon^® has been recognized around the world.  With the introduction of this valve we present an affordable (same price as most gate valves) ball valve that will outlast any unprotected metal valve in any application.

The lubricity of our Teflon® ball allows for lower torque ratings in any application, making it easier to turn; and it requires a smaller, less expensive actuator.

We offer a complete line of actuators, gear operators, and operating nuts for the 4000 series. Our unique Teflon® fused ball, and lower operating torques, make the 4000 series an effective alternative to cast iron gates, carbon steel ball valves, and plug valves. The four-bolt actuator mounting pad is ideal for applications requiring automation.

Advantages of the 4000 series over butterfly valves...

• Face to face and flanged dimensions conform to ANSI standard B16.10, which exactly match end to end dimensions of all cast iron gate valves and plug valves.
• Blow-out proof stainless steel stem.
• Adjustable length/ removable handles to fit into areas of limited space.
• Lockable in full open or closed positions.
• Mounting pad for easy actuation.
• Available in sizes 1/2" through 10"
• Full port through 6"
• Reinforced teflon seats.
• Zero lead
• This patented cast iron ball valve has been engineered to replace any IBBM gate valve, all iron gate valves, or plug valves
