The patented "floating piston" rides up and down in the cylinder with flow surges. As flow pressure is reduced, the piston softly settles on the seat to prevent backflow. Opening and closing actions are positively controlled to minimize pulsation and to eliminate chattering.

Available in line sizes 1" - 20", class 150-2500.
