– 3-WAY VALVES 2600 DA – 5600 DA – 5700 DA - 2600 RA – 5600 RA - 5700 RA
ATTENTION
IF THE VALVE IS FITTED WITH A SOFT SEAL, CONSIDERING THE
COMPLEXITY OF THE OPERATIONS FOR BODY GASKET/S REPLACEMENT, YOU ARE
ADVISED TO CONTACT OUR SUPPORT SERVICE.
For all 3-way Mixer (2600-5600) and Diverter (5600-5700) valves, the replacement operation of the gasket cannot be
carried out with the valve assembled on the tubing.
Once the valve is dismantled from the tubing, air must be given to the servomotor to position the valve at half stroke,
then proceed as follows: Fig. example “
2600 DA
– 5600 DA
”
Unscrewing the plug locking nuts ref. 3 with the relevant washer ref. 4, if the valve is model 2600-5600, the plug remains
inside the compartments (same applies for 5700 DN15-20 ), then unscrew the locking nuts ref.17 and remove the
servomotor / bonnet / trim assembly, remove the old gasket, clear the compartment carefully and proceed to replace
the gasket ref.9.
Then, proceed to assemble in the reverse order.
If the valve is model 2700
– 5700 DN25-200, the lower profile ref. 5 – see figure example “2700 RA – 5700 RA” next
page, it will be removed from the stem and remain in hand together with the locking nuts and relevant washer.
Then, the servomotor / bonnet / trim assembly can be removed.
For 5700 type valves, you are always advised to firstly remove the trunk ref.1°, to facilitate the unscrewing operation of
the internal nuts and obviously to replace the lower gasket of the trunk.
