Viton Fluoroelastomer Balls
| General Information: |
| The resilient and compliant quality of these seam-free, synthetic rubber balls offers a number of advantages in non-return valve applications. Being relatively soft they provide a good seal at low pressures and eliminate the need for highly accurate seatings which are often costly to produce. Also they dampen vibration, are quiet in operation and extend valve life. |
