Cla-Val – 81-12 Check Valve

Product Description:

The Cla-Val Model 81-12/681-12 Check Valve is a hydraulically operated No-Slam Check Valve. This valve opens when the pressure at the inlet exceeds the discharge pressure. A gradual rate of opening prevents sudden opening surges. When a pressure reversal occurs, the higher downstream pressure is applied to the cover chamber through the control tube lines, and the valve closes drip tight.

The Cla-Val Model 81-12 does the work of a standard wafer check valve and provides many additional benefits that make it an ideal choice for variable speed drive pump applications where a check valve is needed to prevent return flow.

Revit Description:

• Clearance zones that can be turned on and off
• Multiple graphical options for detail levels and lines
• Maximum and minimum values shown for design assistance (in addition to passing flows)
  • Operating temperature
  • Working pressure
  • Flow rate
• Ready to Try? Both metric and imperial Revit BIM content assets are available for a variety of Cla-Val valves with different connection types.
