� The minimum wall thickness for butt welding connection must be greater than or equal to the largest value of either the calculated minimum thickness of butt welding connection or the nominal thickness of the pipe as indicated on data sheet.
� If the butt welding connection has a yield strength lower than the yield strength of the pipe to which it is intended to be welded, the wall thickness in each zone of the butt welding connection is at least equal to the specified pipe wall thickness times the ratio of the minimum yield strength guaranteed by the specification of the steel of the pipe and the minimum yield strength guaranteed by the specification of the steel of the butt welding connection.
� The specified pipe wall thickness and grade (with reference to the equivalent grade in API 5L spec. or ASTM spec.) with which the valve is intended to be used is specified in the data sheet/piping class.
4) The Manufacturer shall submit for approval to the Control Authority and to the Purchaser/Engineer the dimensional drawings, the calculation of the parts used for the welding connection to the pipeline and the material part list for all the types of valves.

Rev. 7 – 08/04/15 Page 7 of 31
6.2.2. Welding ends
The connecting pipe outside diameter, wall thickness, specified minimum yield strength and material grade are mentioned in the relevant piping specification and valve data sheet.
Butt-welding ends shall be in accordance with figure 1 for wall thickness up to 20.0 mm; for thicker walls, refer to figure 2. The inside diameter at the welding end shall be equal to that of the pipe on which the valve shall be welded. If a welding end of a valve has a thickness not equal to the pipe with which it is intended to be used, the welding end preparation at the joint has to be in conformity with fig. 3.
The tolerance of the inside diameter at the bevel end shall be following :
NPS Tolerance of inside diameter at bevel end (1) (mm)
2" - 10"
12" - 48"
+ 1.6
+ 2.4
-0.4
-0.8
(1) Tolerance refers to variation from specified ID calculation by (OD spec. - 2t spec). OD = outside diameter t = wall thickness
The out-of roundness at a welding end, defined as the difference between the maximum and the minimum inside diameter at the welding pipe end shall not exceed 1% of the specified inside diameter.
The length of the butt end shall be sufficient to allow welding and heat treatment without damage of the internal parts of the valve. If Purchaser/Engineer accepts design which do not meet this requirement, than Manufacturer shall inform the Purchaser/Engineer about the precautions which needs to be fulfilled in order to guarantee that during welding of the butt welding ends no damage shall occur to the seat. These precautions shall be highlighted by the Manufacturer in the erection and installation instruction book.

6.2.4. Design features
All ball valves shall be full bore - to allow pigging - unless stipulated otherwise on the valve data sheet.
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.

� Electrical material shall be conform to IEC classification IP65 for area classification zone 1, gas group IIB, temperature class T4 minimum according to CENELEC/European standards.
Protection modes of the solenoid valves shall be Eexd, e or m. Voltage shall be 24 VDC.
For the position switches : Eexd +e, or i.
For junction boxes : Eexd with only one outlet cable gland for the multi-wire, Purchaser/Engineer cable.
� Choice and design of the actuator shall be based on the following criteria :
� The design of the actuator system, the machining precision of its components and the choice of the moving part material shall be such as to guarantee performance with a long-life and great accuracy. Particularly, great care shall be taken for the corrosion resistance, roughness and hardness of the friction surfaces of the moving parts.
� Actuator shall be able to produce 150% of the mechanical power (couple, translation force, etc…) required to open the valve form the fully closed position and under the required maximum design differential pressure of the valve and perform the travel under the required stroke time. For pneumatic (gas or air) and hydro-pneumatic (gas-over-oil) actuators, this condition shall be fulfilled with the minimum pressure of the air or gas supply. Moreover, the curve power/valve travel of the actuator shall be suitable for the resisting forces of the valve during full travel.
� The actuator shall be equipped with torque limiting devices, if required, for operation with full maximum pressure of the motor fluid.
� Unless otherwise specified in the data sheet, actuators shall be equipped with an emergency, local device to open or close manually the valve. This device consists generally of a hand-wheel for pneumatic and electrical actuators, and of an oil handpump for oil-over-gas ones. The manual operating device shall be safe, normally de-clutched and thus shall not move when actuator is in operation. A de-clutching device, generally a lever, shall permit a safe manual operation without any influence of a remote signal : manual operation shall have the full priority over motorised operation during the whole de-clutching duration.
Moreover, when required, local motorised operation shall also be possible, to open or close the valve, by means of push button(s) generally. Electrical actuators shall always be equipped with these local, motorised operation devices.
� The required failure position of the valve, as mentioned in the data sheet (generally fail as it is) shall be guaranteed as soon as one of the following supply is lost :
� remote electrical control signal
� gas or air for pneumatic or gas-over-oil actuators
� electrical power supply for electrical actuators (causes always "fail as it is" position).
� Actuator shall be equipped with local position indicators and position limit switches (open/closed) for remote indication.
� When required in the data sheet, actuator shall be equipped with a positioner in order to receive a remote proportional signal for intermediate position of the valve.
