3PC Ball Valve


Economy, polymer-seated, 3-piece ball valves provide a lower cost solution in many applications.

3PC Ball Valve

What is a 3PC Ball Valve?

Ball valve components in high-cycle and heavy pressure applications experience a lot of wear and tear. Three-piece ball valves are ideal for these applications because replacing and servicing parts can be done quickly and easily.

3 piece ball valves are most commonly found in manufacturing facilities and are available in a wide variety of connection types, including:

  • Female National Pipe Taper (FNPT)
  • Socket Weld
  • Tube Socket Weld
  • RF Flange

Exclusive in ZECO Valve’s 3pc ball valves, the assembly bolts can screw directly into the assembly flanges. There are no assembly nuts to be dropped or lost when installing or servicing the valve.

Features of 3PC Ball Valves

Since the main body of a 3-piece ball valve can be removed for cleaning and maintenance, it is often the most cost-effective option in the long run. Changing seats and seals is more affordable than replacing the entire valve, and not having to remove the pipe connectors prevents a line shutdown should maintenance be required.
