o
Near total zero setting of the pressure in the delivery line at gun closure.
Advantages:
o
At gun reopening, work pressure is reached gradually.
Advantages:
o
Reduced pressure loss and hardly dependent on flow rate.
o
Great reliability.
o
Easy maintenance.
o
Three versions with different working pressure but one sole range of flow
rate from 9 up to 40 l/min.

- Page 2 At gun closure, the special mechanism of zero setting patented by PA, which does not include a check valve, keeps in connection the delivery line and the bypass line, in that way permitting to lower the pressure all around the system and not only in the source line of the valve.
- Page 3 Ultimo aggiornamento: 15/11/19 DISCHARGE SYSTEM AND WATER ADDUCTION The valve can be fitted on machines fed directly by the water system with bypass recycle to the pump or on machines fed by a tank where the bypass flow is also discharged. In certain conditions, depending on installation and in particular: through feeding from tank, with long delivery lines or strong difference in level,...

STANDARD: every 400 working hours, check and lubricate the seals with water resistant grease. SPECIAL: every 800 working hours, check the wear of the seals and internal parts and, if necessary, replace with original PA parts taking care, during installation, to lubricate with water resistant grease. - Page 6 60.2900.00 VB40/1000 Zero Unload.-flow activated Pos.
