PART 3 EXECUTION

3.1 EXAMINATION

A. Verify that conditions are acceptable for product installation in accordance with manufacturer's instructions.

B. If preparation or conditions are the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.

3.2 PREPARATION

A. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

B. Inspect adjacent pipeline; remove rust, scale, welding slag or other foreign material.

C. Ensure that valve seats and pipe flange faces are free of dirt or surface irregularities that may disrupt flange seating and cause external leakage.

D. Inspect valve disc seating surfaces and waterway and eliminate dirt or foreign material.

3.3 INSTALLATION

A. Install in accordance with manufacturer's instructions.

B. Valve Installation:1. Do not use gaskets between pipe flanges and valves unless instructed otherwise by

valve manufacturer.2. Verify suitability of valve for application by inspection of identification tag.3. Mount actuator onto valve prior to installation.4. Handle valve with care so as to prevent damage to disc and seat faces.5. Valves in horizontal pipelines should be installed with stem in horizontal position to

minimize liner and seal wear.6. Ensure that valves are centered between bolts before bolts are tightened and then

opened and closed to ensure unobstructed disc movement. If interference occurs, due for example to pipe wall thickness, taper bore adjacent piping to remove interference.

22 05 23-23

7. Install butterfly valves with disc in almost closed position.

C. Actuator Installation:1. Air hoses or electrical connections to be made by actuator manufacturer.2. Cycle valve operation from fully closed to fully open, then back to fully closed.3. At same time, check travel stop settings for proper disc alignment.

3.4 ADJUSTING

A. Check valve installation for proper alignment.

B. Turn valve fully open and closed 3 or 4 times to ensure smooth operation and proper seating.

C. Test and adjust relays, timers and counters for proper function.

3.5 PROTECTION

A. Protect installed products until completion of project.

B. Touch-up, repair or replace damaged products before Substantial Completion.

3.6 FIELD QUALITY CONTROL

A. Site Tests, Inspection: Inspect completed assembly for proper locknut screw-in depth, after installation and prior to final acceptance. Report component damage to the Architect.

3.7 CLEANUP

A. Upon completion and verification of performance of installation, remove surplus materials, excess materials, rubbish, tools and equipment.
