DIALOCK® 2-way diaphragm valve

 Open the catalog to page 1

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 •...

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.

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...
