60.5450.00 VRPP 600
- Pneumatic piston control.
- Pneumatic piston at max pressure => max defined pressure;
without air pressure => circuit in low pressure
- Possibility to vary the working pressure by adjusting the air feed
pressure
- Possibility to adjust the max working pressure mechanically.
- Usable with a multiple number of lances.
- High balancing to guarantee slight variations of the rated
pressure when the flow varies in bypass.
- Fixing device PI.EFFE.CI. AC6-45 - M6 screws UNI 5391.
Technical specifications
- Valve body in stainless steel 303
- Parts in Brass and 303 Stainless Steel
- Pneumatic cylinder Alluminium.

    Last update: 03/11/2011 DIMENSIONAL DRAWING DESCRIPTION The valve has an inlet fitting, an outlet fitting and a bypass fitting with G ½” F threading. A pneumatic jack is fitted to the valve with a feed fitting G ¼” F thread. SELECTION This product is to be utilized with clean fresh water, even slightly additivated with normal detergents.
  • Page 3 Last update: 03/11/2011 PRESSURE ADJUSTMENT/SETTING The adjustment has to be made with the system under pressure and the gun open and with the air feed pressure at 4 bar – 0.4 MPa. Vary the pressure by screwing/unscrewing the jack head (pos.24). This operation will be less difficult if the correct nozzle has been chosen.
