USE

Power the valve using a suitable control device (refer to 

Tab. 1

 for the exact absorption values).

CAUTION: Do not run light valve for a long time, the inside gaskets could be damaged and 
the valve could block up.

MAINTENANCE

The electric ball valves of the 853 series do not require any particular maintenance.
Internal cleaning can be carried out when the system to which the valve is connected is cleaned. If the 
maintenance man needs to open the valve to check the seal or for extraordinary cleaning, before fitting it 
back you must replace the seal kit of the orifice that was opened.

CAUTION: Fitting back the valve without replacing the seal kit can reduce the seal on the 
internal ball and therefore cause leaks.

- Unscrew the bolts related to the orifice to be opened, then remove it and take out the inner gaskets and 
the O-ring inserted in the internal seat of the flange that has been removed.
- Re-position all the gaskets in their seats, as shown in 

Fig. VI

 (gasket (

1

) is not present on all models), 

then close the flange.
- Insert the bolts in the holes, fit back the washers and screw in the nuts by hand.
- To ensure correct operation, the nuts (

2

) must be tightened using a dynamometric spanner calibrated 

according to that which is indicated in 

Tab. 1

.

- Reconnect all the hydraulic connections.
- Restore electric power supply.
- Put the system under pressure ONLY WITH CLEAN WATER and check that the connections are not leaking.
