TECHNICAL DATA PRESSURE VARIATION ACCORDING TO TEMPERATURE For water and harmless fluids to which the material is classified as CHEMICALLY RESISTANT. In other cases, a reduction of the nominal pressure PN is required (25 years with safety factor). Pressure drop PRESSURE DROP GRAPH KV100 FLOW COEFFICIENT The Kv100 flow coefficient is the Q flow of litres per minute of water at a temperature of 20°C that will generate ∆p= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely open.

RELATIVE FLOW COEFFICIENT GRAPH 100 90 Relative flow coefficient The relative flow coefficient refers to the variation in the flow rate as a function of the valve opening stroke.

FASTENING AND SUPPORTING All valves, whether manual or actuated, must be adequately supported in many applications. The DK valve series is therefore provided with an integrated bracket that permits direct anchoring of the valve body without the need of other components. For wall installation, dedicated PMDK mounting plates which are available as accessories can be used. These plates should be fastened to the valve before wall installation. The PMDK plate also allows the DK valve to be aligned with FIP ZIKM pipe clips. d CUSTOMISATION The DIALOCK® DK DN 15÷65 valve can be customised using a...

INSTALLATION Before proceeding with installation. please follow these instructions carefully: (these instructions refer to union end versions). The valve can be installed in any position and in any direction. 1) Check that the pipes to be connected to the valve are aligned in order to avoid mechanical stress on the threaded joints. 2) Unscrew the union nuts (11) and insert them on the pipe segments. 3) Solvent weld or screw the end connectors (10) onto the pipe ends. 4) Position the valve body between the end connectors, making sure that the socket seal O-rings (9) do not exit their seats....
