Tender specification: Oventrop connection fittings “Multiblock T” with presetting for regulation, isolation, draining and filling. Distance between pipe centres 50 mm. 2 °C up to 120 °C Operating temperature ts: (for short periods up to 130 °C) Max. operating pressure ps: 10 bar (PN 10) Max. differential pressure: 200 mbar Body made of nickel plated brass (marking “OV 2” on the valve body), stem made on stainless steel with double O-ring seal. Isolating stem made of brass with O-ring and cap with flat seal made of PTFE. Technical data as “Series AV 6”. G 3⁄4 supply and return pipe connection according to DIN EN 16313 (cone “Euro”) for Oventrop compression fitting (alternatively, the compression fittings of other manufacturers – except for composition pipe “Copipe” – which are suitable for the connection to male thread G ¾ according to DIN EN 16313 (cone “Euro”) may also be used). Plastic design covers in white, anthracite, chrome plated or stainless steel finish are available as accessories. Item no.: 1184013 1184014 G 3/4 Application: Two pipe central heating systems, max. operating pressure 10 bar (PN 10), operating temperature 2 °C up to 120 °C (for short periods up to 130 °C) irrespective of the type of heat source. When choosing the operating fluid, the latest technical status has to be considered (e.g. VDI 2035 – Avoidance of damage to hot water heating systems). To guarantee a silent operation, the differential pressure across the fitting should not exceed 200 mbar in any operating status. For use on radiators with supply and return pipe connection. Installation can be carried out with any standard pipe material. Oventrop offers suitable compression fittings for copper, stainless steel, precision steel and plastic pipes as well as the composition pipe “Copipe”. The corresponding installation instructions are to be observed. 31 60 OV 2 50 G 3/4 114 Dimensions of straight pattern model G 3/4 34 Advantages: Oventrop connection fitting “Multiblock T” for the connection to all radiators with a distance of 50 mm between the pipe centres – for regulation – for isolation – for draining – for filling – flow rate presettable Free choice of connection to the supply or return pipe, i.e. the valve is bi-directional (junction points in the pipework are avoided). 34 1184083 1184084 Function: Combined with a thermostat (e.g. “Uni XH”), the Oventrop connection fittings “Multiblock T” are proportional regulators working without auxiliary energy. They regulate the room temperature by varying the volume flow of heating water. The radiator is drained at the isolating and draining screw with the help of the service tool, item no. 1090551. 2014 Oventrop “Multiblock T” OV 2 31 50 114 G 3/4 Models: “Multiblock T” for radiators with: G 3⁄4 male thread according to DIN EN 16313, Straight pattern Angle pattern Rp 1⁄2 female thread, Straight pattern Angle pattern 24 Dimensions of angle pattern model 1 “Multiblock T” Connection fittings for two pipe heating systems Presetting Pressure loss ∆p [kPa] Pressure loss ∆p [mbar] Pressure loss ∆p [kPa] Pressure loss ∆p [mbar] Presetting Flow rate V· [l/s] Flow rate V· [l/s] All patterns at 1 K P-deviation Presetting All patterns at 2 K P-deviation 1 2 3 4 5 6 kv-value at 1 K P-deviation 0.08 0.13 0.20 0.22 0.25 0.28 kv-value at 1.5 K P-deviation 0.08 0.15 0.26 0.32 0.37 0.42 kv-value at 2 K P-deviation 0.08 0.15 0.28 0.37 0.44 0.52 0.75 kvs Performance data Gedruckt auf chlorfrei OVENTROP GmbH & Co.
