The Duraline Control Valve is completely renewable by replacing the internal cartridge per SEFA 7-2010-8.2a.

  • For Duraline globe/straight (180 deg) pattern control valve body, use:
    • DL-RC180-PVD
  • For angle (90 deg) pattern control valve body, use:
    • DL-RC-PVD

There is a small difference in the length of the needle/stem depending on the lab fixture control valve style.

Note: DL-RC180-PVD and DL-RC-PVD are used in all Duraline control valve bodies regardless of fixture material or size.
