Welding
Step 1
1. Weld the valve body halves into the pipelines.
2. Maintain the minimum clearance (A) so that the actuator can be removed.
3. If welding both valve body halves, ensure that they can be moved axially B1 mm, so that the valve parts can be removed.
4. After welding assemble the valve in accordance with the steps 1-5 in section 5.3 Valve assembly.
Pre-use check
Open and close the valve several times to ensure that the valve disc moves smoothly against the seal ring.
