Installation of water flow regulator

Automatic direct-acting flow regulators are technically complex pipeline equipment, so before installation, be sure to study the installation instructions and pay attention to the following recommendations:

• Manometers should be installed before and after the regulator to monitor its performance.
• It is recommended to install a flow meter on critical sections to monitor the regulator's performance.
• The regulator housing should not be subject to torsion, stretching, bending or compression from connected pipelines.
• Flow regulators are unidirectional, so the direction of water flow at the installation site should correspond to the arrow on the housing.
• Flow regulators should be installed on a horizontal or vertical pipeline, unless prohibited by the installation instructions.
• Direct-acting flow regulators are very sensitive to the presence of mechanical inclusions in the flowing water, so it is mandatory to install mesh filters in front of them.

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:
