A shutoff valve must be installed between the PLLD pipe tee and the product pipeline. s IIS NOTE: A shutoff valve is required to complete , the PLLD start-up procedure. 6. A dielectric union must be installed between the j I� PLLD check valve and metal piping. A standard union may be used if the piping is fiberglass. SEALING SURFACE 7.
