8.  Spare parts 

 
With their sturdy construction and use of high-quality materials, ROFI

 

Valves have a long service life. 

Nevertheless certain components can wear or fail because of: 
 

 

extremely frequent operation, 

 

excessive vibration in the piping system, 

 

excessive external stress on the valve, or 

 

inadequate maintenance. 

 
Spare parts for components which the Client is able to fit himself using standard tooling are available from 
ROFI S.A.R.L.. For storage and fitting we recommend close attention to the catalogue documents and 
drawings. In terms of storage, it must be remembered that soft seals, certain plastics and lubricants can 
deteriorate over long storage periods and will not function as required. For best results, store these 
products in dry rooms at a temperature of approx. 20°C to achieve a storage life of 4 to 5 years. When 
ordering spare parts, you should specify: 
 
Type of valve, diameter nominal, pressure rating, material, drawing number and- where possible - the 
Purchase Order Number under which the valve was first supplied. 
 

9.  Guarantee / Warranty 

 

The extent and period of warranty cover are specified in the "Standard Terms and Conditions of ROFI 

 

S.A.R.L." valid at the time of delivery or, by way of departure, in the contract of sale itself. We guarantee 
freedom of faults in compliance with state-of-the-art technology and the confirmed application. No 
warranty claims can be made for any damage caused as the result of incorrect handling or disregard of 
operating and installation instructions, datasheets and relevant regulations. This warranty also does not 
cover any damage which occurs during operation under conditions deviating from those laid down by 
specifications or other agreements. Justified complaints will be eliminated by repair carried out by us or by 
a specialist appointed by us. No claims will be accepted beyond the scope of this warranty. The right to 
replacement delivery is excluded. The warranty shall not cover maintenance work, installation of external 
parts, design modifications or natural wear. Any damage incurred during transport should not be reported 
to us but rather to the competent cargo-handling depot, the railway company or carrier company 
immediately or else claims for replacements from these companies will be invalidated.
