MAINTENANCE
The following maintenance must be performed for the product to operate as intended. Failing to do so voids the warranty.
MAINTENANCE PLAN
Every six months:
•
To check for proper function, a full open/close operation must be performed. Long periods without use can cause
the gaskets to get stuck in place. The valve should operate smoothly and without sudden resistance. Jerking
motion is a sign of sticking gaskets.
•
Refill the bearing housing with bearing grease using the grease nipple. SKF LGWA 2/0.4 or similar is recommended
for 0-40°C. For temperatures below freezing a lower viscosity grease is recommended. (Only applies to SVM-TG
and RVM-TG sizes DN710/NPS28 and above)
•
Inspect the devise for visual signs of damage. If any significant damage is found, please contact Wapro for advice.
EVERY 12 MONTHS:
•
If supplied with AUMA actuator, the actuator has an internal movement counter to keep track of movements.The
gaskets should be inspected for wear or tears. This can either be done using a camera sent though the pipe system
or by disassembling the valve (Described on the following pages)
