GP3T4C Schematic

The GP3T4C is an investment cast 3-valve manifold with flanged instrument and standard integral tube fitting process connections. It bolts directly onto 2-1/8" to 2-1/4" center to center DP transmitters. The GP3T4C eliminates any thread contact with the process fluid (reduces possible leaks, loss of accuracy, or hazardous conditions).

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 GP3T4C is available in 316L stainless steel or a lower cost series 300 stainless steel. Seals are available in teflon or grafoil.

The GP3T4C can be mounted to a 2" pipe using the D/A Mounting Bracket option for easy installation and maintenance.
