APPLICATIONS AND USES
“Y” pattern strainers are typically used in applications where the amount of solids to be removed is small, and where frequent clean-out is not required. Rastelli “Y” pattern strainer are suitable for water systems, for low temperature hot water systems. In addition, bronze valves are suitable for chilled systems and for applications in the marine field.
INSTALLATION AND MAINTENANCE
It is suggested to install the “Y” strainer following the arrow marked on the body and with the cap facing down, so that when it is opened, all the collected impurities on the straining component, will go out and they will not go back inside the pipe. Before installing the “Y” strainer, it is advisable to check if there is enough space to take out the straining components.

Please refer to product literature for more information. Forward sorted material to recycling (e.g. metallic materials) or dispose it, according to local and currently valid legislation taking into consideration the environment.
