LOTUS Back Pressure Regulator/Relief Valve (BPR20) maintains constant pressure and constant analyzer flow while protecting critical sampling components as a relief valve.
BPR20 relief valve holds a constant pressure of 20 psig at the analyzer inlet when installed as recommended. This pressure is maintained independent of source pressure fluctuations or sample flow changes.
This unit also acts as a relief valve in the event of an over-pressure condition.
Features
Precise pressure reduction and control when used in conjunction with a HPRV or Needle valve
Most effective way to assure a constant flow rate to on-line analyzers
Specially designed for steam/water sampling service (SWAS)
Non-plugging design
Fail safe design
