Industrial Ball Valves / 4001 Flanged Ball Valves

Stainless Steel flanged ball valve with PFA* fused ball

4001The ultimate in corrosion resistance.

Investment cast 316 Stainless Steel with all Stainless Steel top works--Even the handle. Other 4001 features such as full port, low torque, and the corrosion-resistance of our PFA* fused stainless steel ball make this valve a winner.

PFA* Fused Ball

The 4000 and 3700 Series feature a PFA* fused ball that is more durable, less succeptible 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 PFA* .008" into a solid metal ball. An additional .004" is added electrostatically for smoothness. Since the PFA* becomes part of the metal, it can't flake, chip, or peel off.

The corrosion and chemical resistance of PFA* 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 PFA* 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 PFA* 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.
