Operated Pressure Relief Valve Type LR128 Fisher
The Type LR128 pilot-operated, pressure relief valve or backpressure regulator is designed for liquid applications. The Type LR128 provides smooth operation, tight shutoff, and long life. Its internally actuated metal plug eliminates disadvantages associated with flexible element style regulators, and the specially engineered flow path deflects debris, protecting the seat from damage and erosion. An internal inlet strainer prevents large particles from entering the main valve.
