TKD DN 10÷50 DUAL BLOCK® 3-way ball valve

FIP has developed a TKD DUAL BLOCK® ball valve to introduce a high reference standard in thermosplastic valve design. TKD is a True Union diverting and mixing ball valve that meets the most stringent needs required in industrial applications. DUAL BLOCyJ DUAL BLOCK® 3-WAY BALL VALVE • Connection system for solvent weld, threaded and flanged joints • Patented SEAT STOP® ball carrier system that lets you micro-adjust ball seats and minimise axial force effects • Easy radial dismounting allowing quick replacement of O-rings and ball seats without any need for tools • PN16 True Union valve body made...

Ergonomic HIPVC handle equipped with removable tool to adjust the ball seat carrier. Possibility of installing the LTKD stroke limiter (available as an accessory) that permits ball and handle rotation only for set opening and closing angles at 90° or 180° (available as an accessory) ergonomically operable during service and padlockable 3 DUAL BLOCK® patented lock system that ensures union nut tightening hold even in severe conditions such as vibrations or heat dilation 4 Ball shutter high surface finish with floating type full passage with T or that compensates axial force guaranteeing optimal...

For water and harmless fluids to which the material is classified as CHEMICALLY RESISTANT. In other cases, a reduction of the nominal PN pressure is required (25 years with safety factor). TECHNICAL DATAPRESSURE VARIATION ACCORDING TO TEMPERATUREPRESSURE DROP GRAPH AND WORK POSITIONS A - T-port ball valve: 0°- Mixing B - T-port ball valve: 90° - Diverting

 C - T-port ball valve: 180° - Branch closed/direct flow D - T-port ball valve: 270° - Diverting E - L-port ball valve: 0°/270° - Diverting

KV100 FLOW COEFFICIENT The K100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20°C that will generate Ap= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely open. The information in this leaflet is provided in good faith.

The LTKD stroke limiter specifically permits handle and ball rotation only at set opening and closing angles. The LTKD090 version permits operations for 90° angles while the LTKD180 version for 180° angles. The LTKD stroke limiter is made up of a single removable plate made of technopolymer. Designed for ISO 5211 bore and specifically designed to be directly housed on the valve body mounting flange. It is secured to the valve body by self-tapping screws or plastic rivets. d * Pipe and glue not included in the KIT

Power Quick/CP The valve can be equipped with pneumatic actuators, using the PP-GR module reproducing the drilling pattern foreseen by ISO 5211

All valves, whether manual or actuated, must be adequately supported in many applications. The TKD valve series is therefore ready to be equipped with threaded supporting brackets (optional) that permits direct anchoring of the valve body without the need of other components. Using standard threaded nuts (not included) made of STAINLESS steel, you can anchor the valve on 4 fastening points.

1) Isolate the valve from the line (release the pressure and empty the pipeline). 2) Unlock the union nuts by pressing the lever on the DUAL BLOCK® (26) along the axis and separate it from the union nut (fig. 1). It is also possible to completely remove the block device from the body of the valve. 3) Unscrew the union nuts (13) and extract the body (7). 4) After turning the handle (2) to the position with the three arrows pointing at the three ports (for L-port ball with two arrows facing the ports a and b), extract the insert (1) from the handle (2) and insert the two protrusions in the corresponding...

INSTALLATION Before proceeding with installation. please follow these instructions carefully: 1) Check that the pipes to be connected to the valve are aligned in order to avoid mechanical stress on the threaded joints. 2) Check that the DUAL BLOCK® union nut locking device (26) is fitted to the valve body. 3) To release the union nuts (13), axially press the release lever to separate the lock and then unscrew it in the counter-clockwise direction. 4) Unscrew the three union nuts (13) and insert them on the pipe segments. 5) Solvent weld or screw the end connectors (12) onto the pipe ends. 6)...
