Installation des Regelventils

Installation of balancing valve is carried out in accordance with the installation instructions, in addition, the following recommendations should be taken into account:

• A strainer should be installed before the valve.
• Pressure gauges are recommended to be installed before and after the valve.
• The installation position can be any, as long as it does not contradict the installation instructions.
• The arrow on the body should coincide with the direction of the water flow at the installation location of the valve.
• The body of the balancing valve should not be subjected to bending, torsion, stretching, or compression loads.
• The installation location of the balancing valve should be accessible for maintenance, adjustment, and flow measurement.
• Different manufacturers provide different data, but on average, it is recommended to maintain straight sections of 5DN before and 10DN after the manual balancing valve.

Sequence for packing a threaded connection

1. Take a flax fiber string with enough threads so that its twisted diameter is approximately equal to the depth of the thread. The length of the string should provide for 1.5-2 times more windings than the number of thread turns.

2. Starting approximately 50-70 mm from the beginning of the string, slightly twist it, place it in the first thread turn, and, holding it with your hand, tightly wind a long branch of the string clockwise, placing it in each thread turn.

3. When reaching the end of the thread, continue winding with a second layer, shifting the turns to the beginning of the thread. The length of the second layer winding should be approximately equal to 2/3 of the thread length.

4. Wind the remaining end of the string (50-70 mm) similarly clockwise, from the end of the thread to its beginning.

5. Apply a layer of sealant to the winding surface.

6. Tighten the connecting elements by hand. With correct packing, the assembled element should turn 1.5-2 full rotations.

7. Continue tightening the element with a wrench or a torque wrench. In case the assembled element needs to be in a specific position, complete tightening it in the necessary position of the element.

With proper packing, during tightening, the force should not exceed the tightening torque listed below:
