6.6.2.6.4 For a lined shell, the internal stop valve required by 6.6.2.6.3.1 may be replaced by an additional external stop valve.

(a) a self closing internal stop valve, that is a stop valve within the shell or within a welded flange or its companion flange, such that

6.6.3.5.3 For filling and discharge openings the first shut off device shall be an internal stop valve and the second shall be a stop valve placed in an accessible position on each discharge and filling pipe.

(a) an external stop valve fitted as close to the shell as reasonably practicable and

(b) an external stop valve fitted as close to the shell as reasonably practicable and

We stop for a drink of water.

6.6.3.5.2 All openings with a diameter of more than 1.5 mm in shells of portable tanks, except openings for pressure relief devices, inspection openings and closed bleed holes, shall be fitted with at least three mutually independent shut off devices in series, the first being an internal stop valve, excess flow valve or equivalent device, the second being an external stop valve and the third being a blank flange or equivalent device.

I'll get some water to stop that bleeding.

6.6.4.5.2 Each filling and discharge opening in portable tanks used for the transport of flammable refrigerated liquefied gases shall be fitted with at least three mutually independent shut off devices in series, the first being a stop valve situated as close as reasonably practicable to the jacket, the second being a stop valve and the third being a blank flange or equivalent device.

Get me some cold water and some towels and stop yapping.

Lynda, stop waving, you'll have Mr Machin fall into the water.

This is called a cycle valve tube.

No stop valve shall be installed between the shell and the pressure relief devices except when duplicate devices are provided for maintenance or other reasons and the stop valves serving the devices actually in use are locked open or the stop valves are interlocked so that the requirements of 6.6.4.7 are always fulfilled.

And this is how you make a valve.

6.6.2.5.2 All openings in the shell, intended for filling or discharging the portable tank shall be fitted with a manually operated stop valve located as close to the shell as reasonably practicable.

(v) the valve shall continue to be effective in the event of damage to the external device for controlling the operation of the valve

This is actually a heart valve, which we engineered.

The external discharge fittings (pipe sockets, shut off devices), the stop valve and its seating shall be protected against the danger of being wrenched off by external forces (for example using shear sections).

No stop valve shall be installed between the shell and the pressure relief devices except where duplicate devices are provided for maintenance or other reasons and the stop valves serving the devices actually in use are locked open or the stop valves are interlocked so that at least one of the duplicate devices is always in use.

The external discharge fittings (pipe sockets, shut off devices), the internal stop valve and its seating shall be protected against the danger of being wrenched off by external forces (for example using shear sections).

6.6.2.5.6 Each stop valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperatures expected during transport.

6.6.3.5.9 Each stop valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperatures expected during transport.

6.6.4.5.8 Each stop valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperature expected during transport.

But Nineveh has been from of old like a pool of water, yet they flee away. Stop! Stop! they cry, but no one looks back.

Does the color of the valve matter? What matters here?

(ii) the valve may be operable from above or below

Connections and accessories leading to or from such a valve shall have a capacity for a flow more than the rated flow of the excess flow valve.

Other openings, except for openings leading to venting or pressure relief devices, shall be equipped with either a stop valve or another suitable means of closure located as close to the shell as reasonably practicable.

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

And the way you engineer this heart valve is the same strategy.

What if a cylinder cracks, a valve stuck, a bearing burned out?

No stop valve shall be installed between the shell and the pressure relief devices except when duplicate devices are provided for maintenance or other reasons and the stop valves serving the devices actually in use are locked open or the stop valves are interlocked so that at least one of the duplicate devices is always operable and capable of meeting the requirements of 6.6.3.8.

To stop the unsustainable exploitation of water resources by developing water management strategies at the regional, national and local levels, which promote both equitable access and adequate supplies.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

Stop, stop, stop!

Stop, stop, stop!

Stop, Erminio. Stop, stop.

It has a funny trilobal shape at the bottom, which contains the aortic valve.

Dave, stop now. Stop. Stop it.
