SF3TC Schematic
  • Investment cast 316SS body bolts directly to transmitter to eliminate need for transmitter oval flanges
  • 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 SF3[TC],[T4C],[FC] are investment cast 3-valve Transmount manifolds with flanged instrument connections. They bolt directly onto 2-1/8" and 2-1/4" center to center DP transmitters. On the process side, they can be supplied with threaded[TC], integral tube fitting [T4C], or flanged[FC] connections.

The SF3[TC],[T4C],[FC] can be mounted to a 2" pipe using the D/A Mounting Bracket option for easy installation and maintenance.

These units were designed to allow the use of a box end wrench on transmitter bolts.
