DANAÏS Cryogen ic :Valves all along the LNG Chain

With its AMRI butterfly valves,

KSB is present all along the LNG

chain, from gas production to

distribution to the final custo-

mer. KSB is a leading butterfly

valve manufacturer for industry

and supplies valves from DN 25

(1’’) to 3000 (125’’), for cooling

water, sea water, steam, inert

gas applications, fire fighting

systems, …

With the DANAÏS Cryogenic

series, you benefit from more

than 30 years of experience and

constant improvements in the

AMRI butterfly valve range. All

over the world, several thou-

sands of DANAÏS Cryogenic

valves are operated by the most

renown companies in the gas

industry – should it be in lique-

faction plants, LNG tankers or

LNG receiving terminals. They

have proven their reliability and

absolute safety in the most

demanding environments.

An outstanding achievement:

almost 60% of existing LNG

tankers are equipped with

DANAÏS Cryogenic valves.

The AMRI butterfly valves are

manufactured by KSB, as well as

the AMRI actuator and automa-

tion series. KSB is able to pro-

vide you with complete solu-

tions, tailored to your specific

needs.

DANAÏS Cryogenic valves are

renown for their easy mainte-

nance. All parts can be easily

replaced: the main parts are

identical for a given diameter,

whatever the valve body type.

Our maintenance centres are

operated by highly skilled tech-

nicians. They are located all

along the main tanker routes or

close to the main production or

reception areas. Most of the

replaceable parts are available

on stock there.

We will assist you at very short

notice for installation, commis-

sioning or regular maintenance

operations.

Different valve types are used on

a LNG tanker or in a terrestrial

installation. The spare part

stocks should be kept to a mini-

mum. KSB took this into

account when conceiving AMRI

butterfly valves and especially

the DANAÏS Cryogenic series.

Most of the replaceable parts

(seat, shaft, disc, gasket holder)

are identical for a given diame-

ter, whatever the body type

(buttweld top or side entry,

wafer, lugged or flanged).

3 layers for unmatched tightness

External sheath: copper or nickel.

Resilient even at low temperatures.

It compensates for minor altera-

tions to the disc surface.

Internal sheath: stainless steel.

Enables the seat to resist pressure

constraints.

Spring: Inconel. Compensates for

relative displacements between seat

and disc due to thermal dilation or

pressure.

Solid seat to resist stress

The seat is machined out of a solid

plate of stainless steel or inconel. It

offers a similar capacity to compen-

sate for relative displacements be-

tween seat and disc and a better

resistance to high pressures.

The reaction ring is no longer a

separate part. Thus, the surface in

contact with the disc is wider.

Pressure disc side: the fluid pressure

pushes the seat against the disc.

KSB is certified ISO 9001. We

use the latest simulation

methods – such as finite ele-

ment analysis and casting flow

simulation – to ensure that our

valves meet the highest require-

ments of our customers.

The standard procedure for

buttweld valves includes radio-

graphic examination of butt-

weld ends and die penetrant

body test.

For its AMRI butterfly valves,

KSB has designed self-centring

metallic seats. They feature a

unique balance of strength to

resist pressure and give flexibili-

ty to compensate for relative di-

lation by temperature changes.

A very high level of upstream/

downstream tightness in the

most severe conditions.

When the disc undergoes mi-

nute deflexion under high pres-

sure, the flexible reaction ring

will evenly push the seat against

the disc, with the required con-

tact pressure to ensure tightness.

All internal parts are metallic,

making the DANAÏS Cryogenic

valves intrinsically fire safe.

The double-eccentric kinematics

eliminate friction during opera-

tion. The disc is hardened with

stellite (i.e. hard chromium),

reducing wear and resulting in a

long service life.

Pressure shaft side (preferred direc-

tion of flow): the disc is pushed

against the seat which rests against

the retaining flange.

F u l l b i - d i r e c t i o n a l t i g h t n e s s :

Full bi-directional tightness: the flexible seat offers the same high

tightness level in both pressure directions.
