GP3FC Schematic

The GP3FC is an investment cast 3-valve manifold with all flanged connections. It bolts directly onto 2-1/8" to 2-1/4" center to center DP transmitters and is designed for direct or remote mounting.

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 GP3FC is available in 316L stainless steel or a lower cost series 300 stainless steel. Seals are available in teflon or grafoil.

The GP3FC can be mounted to a 2" pipe using the D/A Mounting Bracket option for easy installation and maintenance.
