All trunnion mounted ball valves shall be fitted with following devices :

� Double block and bleed : design of a valve with two seating surfaces between which the cavity can be vented through a bleed connection and thus confirm the tightness of the valve, at least in closed position, when pressure is applied to any side or both sides of the valve.

� Double piston effect : when the pressure is applied to one side, let us say "upstream" side, and when upstream ball seat is leaking, transfer pressure shall have a positive shut-off effect on the downstream seat (acting, for instance, on the back face of this seat) and thus reinforcing the global tightness of the valve.

� Anti-static design : all ball valves shall be fitted with anti-static device conforming to BS 5351.

� Stem retention (anti blow-out) : In conformity with BS 5351 valve shall be designed with an anti blow-out stem so that the stem cannot be fully ejected by pressure inside the valve with the stem packing, gland retainer bolting removed.

� Secondary seat and stem sealing : all ball valves NPS 6" shall be fitted with a secondary stem sealing and all ball valves greater or equal to NPS 8" shall be fitted with a secondary seat and stem sealing. This system permits an injection of sealant and shall be fitted with an integral check valve. The number and the location of sealing points shall be on the Manufacturer's responsibility.

Purchaser is allowed to request the check of this system design and its operation, specially for modified or new valve model.

� A drain connection shall be located at the lowest part of the body cavity.

6.2.5. Auxiliary connections

4) Stripping insulation from wire shall be done without nicking the conductor. Although this is of greater importance with solid wire than with stranded wire, it is a matter of concern with stranded wire also. The simplest way of avoiding nicks is to use stripping tools of proper design.

5) Insulated taper pins or spade lugs shall be used for all sizes of stranded wire. CONTRACTOR shall have proper tools to make these connections.

6) All wires or leads terminated at a connection shall have sufficient slack to reduce the effects of vibration. In application where multiple wires are routed from a common cable trunk to equally spaced terminals, the vibration bends shall be uniform in length to prevent stress on any one wire. Proper cable support is necessary to avoid having cable weight supported from wire terminations.

Tubular heat shrink sleeves shall be installed on stripped pairs. The sleeves shall be applied immediately after stripping to prevent unravelling of the aluminum adhering mylar tape.

Since only one end of a shield is grounded, each cable has an ungrounded end. This cable end is finished with no ground, and insulation is applied over the trimmed cable end to avoid accidental grounds on any exposed shield or the shield drain wire. Each shield shall be grounded in the control room or in the instrument room.

Special care shall be taken to ground to the correct system, as indicated on the drawings.

10) Hot air heating equipment shall be provided to heat up the cables if connections have to be made when temperature is lower than 5°C.
