Back Pressure Regulator

Features: The Type-700BP Back Pressure Regulator is a high flow, highly accurate pneumatic relief valve with an adjustable set point. It’s primary function is to provide protection against over pressurization in the downstream portion of a pneumatic system. This precision unit is capable of handling flows up to 50
SCFM. A rolling diaphragm provides the sensitivity that causes the Type-700BP to vent to atmosphere in response to the slightest upstream changes.
