## Summary description

FERRO K20 is a 1/2" check valve with an integrated suction strainer designed for water systems. It prevents backflow while filtering debris at the inlet, protecting pumps and piping. Suitable for domestic and light commercial applications where reliable one-way flow and inlet protection are required, such as booster sets, suction lines and circulation loops.

## Long description

FERRO K20 1/2" check valve with suction strainer is designed for water systems where reliable one-way flow and inlet protection are required. The unit combines a non-return valve function with a built-in suction strainer to prevent backflow and to filter out debris before fluid reaches pumps or piping. Constructed for domestic and light commercial applications, the compact K20 integrates into suction lines, booster sets and circulation loops to reduce the risk of pump damage and system contamination.
Advantages
The combined check valve and suction strainer reduces the number of components in a suction line by integrating two functions into one device, saving installation space and time. The internal strainer captures particles and protects downstream equipment without impeding normal flow under operating conditions. The 1/2" connection size suits common residential and light commercial plumbing, while the valve’s simple mechanical design provides reliable, maintenance-friendly operation.
Suitable for
 Booster pump suction lines
 Domestic water supply and circulation loops
 Small commercial water systems and pressure boosting
 Pump protection on suction side installations
Key specifications
 Connection size: 1/2"

 Design: compact inline body with internal mesh strainer
How to use
Install the FERRO K20 in the suction line with the flow direction aligned to the arrow cast or marked on the valve body. Ensure the unit is accessible for periodic inspection and cleaning of the strainer element. Before commissioning, flush the system to remove loose debris, then check for leaks at threaded or joined connections. Verify proper operation by observing one-way flow and confirming the absence of backflow when the pump is off.
Usage recommendations
To maintain performance, inspect and clean the suction strainer at regular service intervals or if flow decreases. Use with clean water systems where particulate contamination is expected; avoid abrasive or chemically aggressive fluids. When replacing or servicing, match the valve’s connection size and orientation to existing piping and follow local plumbing codes.
