Bubble tight seating, true in-line maintainability, extremely easy seat replacement and long, trouble-free service life in a very simple and rugged design. 
All of the Ball-Plex™ units are standard with 316 SS balls and PTFE seats. Other alloys are also available for the balls. Available from stock in cast iron, bronze, carbon steel and stainless steel. Other alloys are also available. Threaded and flanged units are available with full rated pressures from Class 125 to Class 300 (Class 600 flanges also available).
