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 and for angle (90 deg) pattern control valve body use DL-RC-PVD. There is small difference in the length of the needle / stem depending on the lab fixture control valve style.

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