Block and Bleed Manifolds

Block and bleed manifolds allow isolation of your pressure instrument.  This, in turn, allows removal of the pressure gauge, switch or transmitter for maintenance without interrupting the process.  In addition, the “bleed” part of a b&b manifold, allows the instrument pressure to vent safely via a separate valve, in a controlled fashion, after isolation and before instrument removal.  For flanged process connections to threaded instruments consider the Monoflange from Stewart Buchanan which reduces potential leak paths.  Through our association with Stewart Buchanan, Fluidic offer a variety of needle and ball valve block and bleed manifolds.

 

Stewart Buchanan Block and Bleed Manifolds

  • J2 – Remote Mount Female:Female (Needle valve)
  • K2 – Angled Bonnet Female:Female (Needle valve)
  • L2 – Remote Mount Male:Female (Needle valve)
  • M2 – Direct Mount Pipe To Flange (Needle valve)
  • N2 – Enclosure Direct Mount Pipe To Flange (Needle valve)
  • O2 – Flat Face Remote Mount (Needle valve)
  • Q2 – Direct Mounted Transmitter Manifold (Needle valve)
  • BVL – Block and Bleed Valve Manifold (Ball valve)
  • BVM – Block and Bleed Valve (Ball valve with Needle Vent)

 

All the above Stewart Buchanan block and bleed manifolds are pressure rated to 413bar (6000psi).  In addition, Fluidic can suply pre-assembled to your instrument and hydrostatically pressure tested, generally to 1.5x the max working pressure.  Block and bleed manifolds are available in a variety of materials, including exotic metals, to NACE standards and with material certification.

 

Another advantage of this device is that, by connecting a test gauge to the vent port, it is possible to check the calibration of the installed instrument without removing it from the installation.

 

Through our association with Stewarts, Fluidic also offer block and bleed isolation manifolds.  Consider the L2 manifold with integral swivel adapter which reduces the number of potential leak paths.  See photo graph above left.
