STRESS RELIEVE Valve insulation is prohibited during stress relieving.
OPERATION ALVE UBRICATION ValvTechnologies metal-seated ball valve requires NO lubrication. Re-tightening of body (with system de-pressurized) and gland packing bolting is permissible, if leakage occurs in these areas. Required Torque values are given in Tables 1 & 2. The use of Copper-Based Anti-Seize Grease for stud lubrication and Molyb- denum Disulfide Anti-Seize Grease for packing lubrication is recommended.
In the event of a conflict between these instructions and those contained in this manual an authorized ValvTechnologies distributor or to ValvTechnologies Houston facility should be contacted. The lubricant of worm gear actuators should be inspected every three months and be replenished or replaced if required.

ISASSEMBLY ONTINUED 1) Valve shall be cycled closed. CAUTION! Balls are matched to end 2) Orientation and position shall be marked on valve components, par- caps – these matched pairs ticularly the side of the ball matched to the seat, prior to removal. should never be separated 3) Marking should be indelible to the valve cleaning process, but should or interchanged.
If ball/end cap cannot be re-lapped. The seat must be re-machined, re-coated and re-lapped to the new ball. This must be done by an approved ValvTechnologies facility. The seat may be re-worked several times, as a rework face tolerance is designed into the end cap.

Only approved ValvTech- NOTE: It is recommended that all internal carbon steel nologies components should be used valve parts and surfaces be coated with light motor oil.
The stem MUST be prevented from being driven into the ball. 9) All operator adapter plates supplied by ValvTechnologies have a machined hole in the middle of the plate. When this plate is mounted to the valve, it should be concentric with the shaft before the bolts are tightened holding the mounting plate to the valve.

Complete Assembly 26) Remove the end cap and insert the body gasket/seal. 27) Recheck/re-inspect the sealing faces on ball, body and end cap to ensure they were not damaged during handling. 28) Replace all damaged body studs. Apply Copper-Based Anti-Seize Grease high temperature com- pound to the threads.
TESTING 1) Valves may be tested in accordance with ValvTechnologies’ Quality Procedure, VQP 010. 2) When performing the seat test, the pressure must be applied on the upstream side. The arrow on the valve (or the label indicating the high pressure end) will indicate the direction in which pressure should be applied.
