Valve: Specifications

Valve Dimensions

‹› Intake and exhaust valves must not be refaced by grinding. Only grinding is permitted.

CAUTION!
Risk of injury if exhaust valves with sodium filling are disposed of improperly.

‹› Cut exhaust valve with sodium filling into 2 parts with a metal saw between shaft center and valve plate. While doing this, do not

come into contact with water.

‹› Throw at the most 10 such sawed exhaust valves in a bucket filled with water and step back immediately.

‹› When there is contact with water, a sudden chemical reaction occurs which burns the sodium filling.

‹› The treated parts may then be discarded through conventional disposal channels.
