Fisher Type LR128
The Type LR128 pilot-operated, pressure relief valve or backpressure regulator is designed for liquid industrial/commercial 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. The Type LR128 is used in conjunction with a Type 98HM pilot and Type 112 restrictor. An internal inlet strainer prevents large particles from entering the main valve, limiting damage to internal parts.
The Type LR128 provides accurate backpressure control and fast response for medium to high-flow applications. Its metal plug and engineered flow path deflect debris, protecting the seat from damage and erosion. The Type LR128 handles a range of liquids; from water, to lube oil, to fuel.
