This valve is solid stainless steel, and so is NSF approved. They are found in some but not all models of Casadio, Dalla Corte, Lelit, Reneka and Sanremo.
Note this valve will only work where the fitting it threads into has enough clearance so that the piston inside can move freely up and down. In some cases, the inside of the female fitting that this valve threads into will not be deep enough, and the piston will bottom out, not allowing it to move.
1/4" gasket not included.
