GP3FU Schematic

The GP3FU is a 3-valve Unimount manifold with all flanged connections that accommodate 2-1/8" and 2-3/16" center to center transmitters. It is designed to bolt onto a 2" pipe. Installation simply requires the tightening of 2 U-bolts - no mounting bracket required.

The Unimount design allows the completion of all piping prior to installation of the transmitter. The built-in manifold mounting system permits easy removal of the transmitter without disturbing the process lines or mounting connections.

An exclusive vent/calibrate valve located between the high pressure block valve and the equalizer valve permits venting and calibration of the transmitter at the manifold.

The GP3FU is available in 316L stainless steel or a lower cost series 300 stainless steel. Seals are available in teflon or grafoil.
