- Our patented PFA*-fused ball resists corrosion better than balls made with unprotected metal surfaces. (Refer to any manufacturer’s chemical resistance guide for further information.)
- PFA inhibits the buildup of lime, calcium, sludge, etc. that accumulates on a ball’s surface and prevents premature failure of the valve seats.
- 4000 Series valves with PFA-fused balls can last up to ten times longer than valves made with unprotected ball surfaces.
- The lubricity of the PFA-fused ball allows for lower torque ratings in any application, and eliminates ball pitting, prevents buildup, lowers torque, and stops premature valve failure.
- Since PFA is actually impregnated .008” into the solid metal, it can’t wear, chip, or flake off.
- Same flanges and end-to-end dimensions as any 125# or 150# gate, ball, or plug valve
- Convenience of quarter-turn operation.
- Certified to NSF 61 & 372 for potable water.
- Polyester powder coating for added strength and lubricity.
4000 Series Industrial & Commercial Valves
4000 Series Valves Lead the Way
American Valve’s 4000 Series™ is a solution without compromise for facility, factory, and municipal managers. Featuring a patented, corrosion-resistant PFA*-fused solid ball, the 4000 Series is more durable, less susceptible to buildup, and longer-lasting than any ordinary ball valve.
Our design provides maximum flow rate free from obstruction and is the ideal alternative to gate, butterfly, and eccentric plug valves. Seats are protected from wear, and automation is a breeze with low operating torque and an ISO standard mounting pad.
With the same ANSI B16.10 end-to-end dimensions as any 125/150 class gate valve or eccentric plug valve, and the convenience of a quarter turn operation, 4000 Series ball valves are used in a wide range of applications around the world. When gate, butterfly, or eccentric plug valves cannot be trusted, switch to solutions from American Valve.

4000 Series Industrial Valve Features
For facility, factory, and municipal managers who are frustrated with corrosion & build-up on their gate, plug, ball, or butterfly valve and not getting bubble-tight shutoff with their gate or plug valves, the American Valve 4000 Series offers a complete family of cost-effective flanged ball valves featuring a patented PFA*-fused ball that outperforms and outlasts ordinary ball valves.
4000 Series valves are easy to open, easy to close, and feature a patented PFA*-fused ball that resists buildup and corrosion to extend valve life. All 4000 Series ball valves are certified by UL to meet NSF/ANSI Standards 61 and 372 for drinking water safety.
Gate valves have been around for centuries, and so have their inherent design flaws. The metal seat rings and discs are constantly exposed to buildup and wear, making them difficult or impossible to cycle. Earlier ball valves were designed for oil refineries, and lacked features needed in water, air, or steam applications.
The Ball
The heart of the 4000 Series is in the ball. Whether using a cast iron ball (for cast iron bodies), or a stainless steel ball (for ductile iron and stainless steel bodies), the 4000 Series uses a ball fused with PFA* that resists surface build-up that prematurely damages the seats. Since the PFA* is fused .008” into the solid metal, it can’t wear, chip or flake off.
Easy Installation
The 4000 Series has the same end-to-end flanged dimensions of any 125/150 class gate, ball or plug valve—making the 4000 Series the optimal choice for both new and retrofit projects.
Certified for Drinking Water Systems
All 4000 Series valves are certified by Underwriters Laboratories (UL) to NSF/ANSI Standards 61 and 372 in both hot and cold applications.
Seats
4000 Series valve seats are made from reinforced Teflon®, with a back ring for low pressure applications. Compared to a traditional gate valve with a Class IV allowable leak rate, the 4000 Series has a bubble-tight shutoff.
Body Coating
Both the interior and exterior of the body is coated with a Polyester powder coat that meets FDA food-grade requirements.
Top Works
The 4000 Series handle is standard A53 steel pipe, and can be easily removed, replaced, or modified. The valve is lockable in the open or closed position. A square nut can be installed for underground or in-vault installations. It’s easy to accessorize with gear, chainwheel, pneumatic, and electric actuators.

How much torque does it take to turn?
Our patented PFA-fused ball means reduced operating torque compared with ordinary ball valves. The actual amount of torque required to operate a valve is dependent upon many variables, such as line pressure, temperature, type of fluid, and frequency of operation.
*PFA is an ingredient commonly branded as Teflon(R).
