  • Pressure regulators

Pressure regulator with pressure gauge (11DO 149B7641M). The adjustable pressure regulator reduces the incoming sanitary water pressure and thus ensures a constant pressure in the internal installation, even when the incoming pressure changes. Due to their design, the bronze pressure regulators are not affected by scale or dirt and require no maintenance.

Composition

  • Pressure regulator
  • Pressure gauge (0-6 bar)
  • 2-piece coupling (2 pieces)

Installation

The pressure regulator is usually mounted just after the water counter to protect the entire installation. The pressure regulator can be mounted in any position (horizontal, upright, upside down, reversed and inclined,...) as long as the direction of flow indicated on the body is respected.

The adjustment of the pressure regulator must be done without flow, i.e. without downstream outflow. The pressure regulator is set at 3 bar as standard.

  • To increase the pressure, tighten the adjusting screw (clockwise when looking at the screw from above)
  • To decrease the pressure, loosen the adjusting screw (counterclockwise as you look at the screw from above), open and close the faucet briefly, then tighten the screw again until the desired pressure is reached.

The complete installation and commissioning instructions can be found in the manual under “Downloads”.
