SF3TU Schematic
  • Valve assembly is process blowout proof
  • The packing controls both stem leakage and leakage between the manifold body and the valve.
  • Built-in zerk nut allows complete online flush-through relubrication
  • Over-torquing of valve handle in either direction is prevented
  • Ceramic ball (up to 8 times harder than 316SS) eliminates ball creasing and seat galling
  • Unit can withstand considerable mechanical and chemical abuse
  • Valve cannot be accidentally disassembled
  • Large (over 1/4") internal porting

The SF3TU is a 3-valve Unimount manifold with flanged instrument connections that accommodate 2-1/8" and 2-3/16" center to center transmitters. Process connections are 1/2" NPT.

The SF3FU is a 3-valve Unimount manifold with all flanged connections that accommodate 2-1/8" and 2-3/16" center to center transmitters.

The Unimount is designed to bolt onto a 2" pipe. Installation simply requires the tightening of 2 U-bolts - no mounting bracket required. This 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.

The SF3FU can be directly mounted to the meter run flanges with the MRM option, for a practical close coupling system.
