Construction Vekotrim 1. Body nickel plated. Shutoff ball valve. Flat sealing Application The Vekotrim double connection fitting is designed for installation onto radiators with with an Rp1/ female thread and male thread. Self sealing connections enable easy mounting to the radiator. Models in angle and straight forms, each designed for twopipe systems, mean that the connection fitting can be used in a number of different ways. For example, the straight form can be used for pipe connection vertical to the floor. If a free floor area is required, the angle form is used for the wall connection. Radiators can be shut off individually with the Vekotrim connection fitting. For dismounted radiators decorating and service work, for example, can be carried out without interruption to other radiators. Mounting of the Vekotrim connection fitting is possible on the left as well as on the right of the radiator. This is especially advantageous when the radiator is turned around. Sample application Twopipe system 1. Vekotrim. Radiator. Thermostatic head
IMI HEIMEIER / Thermostatic Heads & Radiator Valves / Vekotrim Note To avoid damage and the formation of scale deposit in the hot water heating system, the composition of the heat transfer medium should be in accordance with the VDI guideline. For industrial and longdistance energy systems, see the applicable codes VdTÜV and 1466/AGFW FW. A heat transfer medium containing mineral oils, or any type of lubricant containing mineral oil can have extremely negative effects and usually lead to the disintegration of EPDM seals. When using nitritefree frost and corrosion resistance solutions with an ethylene glycol base, pay close attention to the details outlined in the manufacturers documentation, particularly concerning concentration and specific additives. Operation Shutoff Supply and return of Vekotrim are closed by using a screw driver (slot size 8. mm x mm) and turning the slots in a horizontal position. 4
