Valve block БКН3 has designs that allow drainage of the impulse line upstream or downstream the isolating valves and connect the monitoring metrology equipment.

The design of the valve block БКН5 allows connecting the metrological control equipment without disconnecting the sensor from the working environment.

Valve blocks БКН3 and БКН5 are designed for connection of pressure difference sensors Sapphire, ЭнИ-100, TZHIU, Metran, AIR and others to the impulse lines.

  • Shutter with self-centering needle valve.
  • Sealing class А according to GOST 9544-2015.
  • Pressure difference sensors connection to impulse lines with the help of mounting flanges.

Manufactured in accordance with the EI.003-00.000 TU

Designations:

    • Ф - elliptic flanges;
    • К1/4 - inner taper thread K1/4";
    • ПР - flat surface of a flange with grooves for rubber ring.
  • Valve block БКН3-4-00 allows to perform the impulse line drainage upstream the isolating valves.
  • Valve blocks БКНЗ-4-10 and БКНЗ-4-11 have the holes with a thread К1/4″ to connect control equipment. They are different by the location of drainage holes depending on the version. The holes have fittings with the plugs screwed into them and allowing for the impulse line drainage next to isolating valves.
  • Valve block БКН5-7-00 is equipped with two additional drain/control valves, through which it is possible to connect the monitoring equipment without disconnecting the sensor from the operating medium.
