Delta Laserline VT DV 3 column radiators

Purmo Delta Laserline Ventil (D2) radiators are manufactured in the same sizes and types and have the same features as Delta Laserline radiators. The main difference is that, unlike Delta Laserline radiators, they are additionally fitted as standard with a pre-set valve insert. The radiator is connected to the system from below via two connection spigots with an internal diameter of G ½”, spaced 50 mm apart (this does not apply to radiators connected to end units). 
In the standard version, on the side opposite the valve insert, there is a welded cover with a G ½” internal thread for convenient fitting of a G ½” air vent, and below this, another cover, also with a G ½” internal thread, for fitting a blind plug.
