DIALOCK® 2-way diaphragm valve

DK DN 15÷65 DIALOCK® 2-WAY DIAPHRAGM VALVE The new DK DIALOCK® diaphragm • Connection system for solvent weld, threaded and flanged joints valve is particularly • Optimised fluid dynamic design: maximum output flow rate thanks to the suitable for shutting optimised efficiency of the fluid dynamics that characterise the new internal geometry of the body off and regulating • Internal components in metal, totally isolated from the fluid and external enabrasive or dirty vironment fluids. The new • Modularity of the range: only 2 handwheel and 4 diaphragm and bonnet sizes for 7 different valve sizes...

High visibility graduated optical position indicator protected by a transparent cap with seal O-Ring Customisation plate: the customisation lets you identify the valve on the system according to specific needs DIALOCK® SYSTEM: innovative handwheel with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in over 300 positions Handwheel and bonnet in high mechanical strength and chemically resistant PP-GR, providing full protection by isolating all internal metal parts from contact with external agents Floating pin connection between the control...

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 customisation...

1) Isolate the valve from the line (release the pressure and empty the pipeline). 2) If necessary, release the handwheel by pressing downwards (fig.5) and rotating anticlockwise to fully open the valve. 3) Unscrew the union nuts (11) and extract the valve sideways. 4) Remove the protection plugs (14) and bolts (13) with the relative washers (12). 5) Separate the valve body (8) from the internal components (4). 6) Rotate the handwheel clockwise to free the threaded stem (5), compressor (6) and diaphragm (7) 7) Unscrew the diaphragm (7) and remove the shutter (6). 1) Insert the compressor (6) on...

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. 5)...
