BYF/RXBF Flanged Back Pressure Valve, 304/316L Self-operated Back Pressure Valve For Metering Pump Pipeline Pressure Stabilization & Relief

RXBF/BYF back pressure valve adopts self-operated diaphragm structure with flanged connection, 304/316L stainless steel body. Two core functions: maintain stable back pressure in pipeline to guarantee stable output of metering pump; automatically open to release pressure when pipeline pressure exceeds set value. Diaphragm soft seal with good sealing performance and weak corrosion resistance. No external power required, driven by medium pressure itself. Widely used in dosing equipment, water treatment, chemical anti-corrosion liquid pipeline, protect pumps and piping equipment.
