MAINTENANCE
•
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)
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)
