BACK PRESSURE / RELIEF VALVE BPR DESCRIPTION The Back Pressure Relief Valve is used to regulate upstream pressure in SWAS for analytical measurement sensors, maintain an constant inlet pressure before the analyzers which help stabilize the flow rate for each analyzer. When some analyzers are installed parallel for a same sample source, the back pressure relief valve can provide constant inlet pressure which allows all analyzers to be able to be shut off at all times without interrupting others. APPLICATIONS • Steam & Water Analysis Systems. • Grab sampling systems. SPECIFICATIONS Wetted parts: Regulated Pressure: Large area diaphragm design to keep constant pressure stable. BACKPRESSURE COLUMN CATIONIC RESIN / RELIEF VALVE BPR. SH.2 CR-60
