10. Maintenance

The maintenance intervals depend on the corresponding application
(product, temperature) and are to be determined by the operator
himself carrying out temporary checks.
The following maintenance recommendation must be verified on the
basis of the individual operating conditions. As the valves are often
used in hot applications or are subject to operating frequencies
of more than 30,000 cycles per year, we recommend half-yearly
preventive maintenance.
Replacement of seals according to Service Instructions.
All seals must be greased well before their installation.
The diaphragm must be greased well at the product-averted
side, only!
Recommendation:
APV assembly grease for EPDM
0.75 kg tin - ref.No. 00070-01-019/03; H147382
60 g tube - ref.No. 00070-01-018/93; H147381
Attention!
Do not use grease containing mineral oil for EPDM seals.
Assembly of the valve according to Service Instructions.
