DIALOCK® 2-way diaphragm valve

The DK DIALOCK® diaphragm valve is particularly suitable for shutting off and regulating abrasive or dirty fluids. The new internal geometry of the body optimises fluid dynamic efficiency by increasing the flow rate and ensuring an optimum linearity of the flow adjustment curve. The DK is extremely compact and very light. The innovative handwheel is equipped with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in any position. DIALOCK® 2-WAY DIAPHRAGM VALVE • Connection system for solvent welding and for threaded and flanged joints •...

DKOAV DIALOCK® diaphragm valve with fixed flanges, drilled ANSI B16.5 cl. 150 #FF PMDK Wall mounting plate

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 or panel installation, dedicated PMDK mounting plates which are available as accessories can be used. These plates should be fastened to the valve before wall installation. PMDK plates also d 20 25 32 40 50 63 75 allow DK valve alignment with FIP ZIKM pipe clips. CUSTOMISATION The DIALOCK® DK DN 15^65 valve can be customised using a...

1) Isolate the valve from the line (release the pressure and empty the pipeline). 2) Unlock the handwheel if necessary by pushing it downwards (fig.5), and open the valve completely by turning it counter-clockwise. 3) Unscrew the union nuts (11) and extract the valve. 4) Remove the protection plugs (14) and remove the bolts (13) with the relative washers (12). 5) Separate the valve body (8) from the operating mechanism (4). 6) Rotate the handwheel clockwise until the threaded stem (5), the compressor (6) and the diaphragm (7) are released. 7) Unscrew the diaphragm (7) and remove the shutter...

INSTALLATION Before proceeding with installation, please follow these instructions carefully: (instructions refer to versions with union ends). 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 the socket seal O-Rings (9) do not exit the seats. 5) Fully...
