Sanitary Ball Check Valves


Waukesha Cherry-Burrell Sanitary Ball Check Valves have a 316L stainless steel body with a curved offset ball trap. Product flow pushes the ball up into the trap and out of the product stream for full diameter flow.

This check valve is well suited to applications where there is pulsing flow and should not be used for sticky, adhesive products, or those with excessive viscosities where the ball can be held in the offset tube.

Product Features:

  • Vertical installations are preferred where product must flow bottom to top to gravity seat the ball.
  • For horizontal check valve installations, the curved offset must be upright and perpendicular to the plane of the pipeline for free-draining and proper ball seating. A minimum liquid pressure is required to seal ball.
  • Waukesha Cherry-Burrell Sanitary Ball Check Valves use larger diameter balls for the tube size than those used by competitors, eliminating the possibility of jamming the ball in the product tube, which can otherwise occur when subjected to high back pressure or hydraulic shock.
  • Choose the ball material to suit various applications
  • either (Buna-N, Viton, or EPDM) or solid nylon.
