Cast iron flanged ball valve with PTFE&#174; fused ball The 4000 and 3700 Series feature a Tefllon&#174; fused ball that is more durable, less susceptible to accumulating buildup and 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 PTFE&#174; .008" into a solid metal ball. An additional .004" is added electrostatically for smoothness. Since the PTFE&#174; becomes part of the metal, it can't flake, chip, or peel off. The corrosion and chemical resistance of PTFE&#174; 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 PTFE&#174; ball allows for lower torque ratings in any application, making it easier to turn and require a smaller, less expensive actuator. We offer a complete line of actuators, gear operators and operating nuts for the 4000 series. Our unique PTFE&#174; 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.
