MAXI Check H – High Pressure Ball Check Valves

Seated Metal High Pressure Ball Check Valves

MAXI‐Check H – High Pressure Ball Check Valves valves are designed specifically for slurry, ash disposal, and mine de‐watering applications. The robust construction ensures years of continuous and reliable use.

The ball is manufactured from Silica Bronze or Stainless steel. As a result, it is able to withstand the mechanical forces exerted due to the high pressures in the systems where it is used. As the media flows through the valve, the ball lifts off the seat/seal arrangement and rolls or rotates as a result of the media moving through the valve. When the flow stops the ball falls into the seat/seal arrangement and prevents any back flow.
