Series LF215 Super Sensitive Low Pressure Regulators are
designed to meet low pressure precision requirements. The
high ratio of diaphragm to orifice provides excellent perfor-
mance and stability at low reduced pressure. The Series LF215
is ideally suited for water requirements up to 2.5 gpm (9.5 lpm)
due to its Lead Free* brass body and brass & stainless steel
internal parts. The LF215 is also suitable for pressure supply to
wall attachment fluidic devices. The LF215 features Lead Free*
construction to comply with Lead Free* installation require-
ments.
Features
• Rugged forged Lead Free* brass body for water service
• Replaceable stainless steel seat
• Large diaphragm provides exceptional performance,
particularly under 10psi (69 kPa)
• 30 mesh stainless steel strainer
