RAVL valve insert set for valve housing 3/4"

Valve insert set for RAVL and RAV valve housing.
The sets make it possible to convert existing RAVL and RAV valve housings to valves that can be pre-set. A set consists of one valve insert and one RA 2990 sensor element with snap-on connection, as a new sensor element with a snap-on attachment must be fitted when the old valve insert is replaced with the RAV/RAVL service insert. It meets the specifications of the EnEV or DIN V4701-10, PAS 1027 and DIN V 18599-5.
