Common Questions
- Does it include a strainer?
- Yes - B1156F (W/PRESS) 1/2 has an integral stainless steel strainer built into the body, so you do not need a separate inline strainer ahead of it. The strainer is removable for cleaning; if the valve starts to lose downstream pressure, pull and rinse the strainer before assuming the seat has failed.
- Does it come with a gauge?
- No - B1156F (W/PRESS) 1/2 has no gauge and no gauge tapping. Set the outlet pressure using a gauge elsewhere on the downstream piping.
