Cone Check

Benefits: 

• Replaces the ball check style valve with a cone, thus providing better flow through and CV values.
• The most versatile check valve option

Limitations:

• Not recommended directly after pumps where cavitation may occur.

Angle Seat Check

• A weighted float at a 45-degree angle provides excellent flow through.
• This is the best-suited non-return valve for installing close to pumps or where cavitation may occur.

• Chemical build-up can occur above the float causing it to seize, regular flushing maintenance may be required.
• Horizontal installation only

Wafer Check

Benefits: 

• Wafer check valves offer a small footprint, as it is installed between two flanges.
• Best suited for larger pipe sizes i.e. greater than DN50 2”.

Limitations: 

• Reduced Bore
• A spacer may be required to allow opening.
