• Safety anti-ejection circlip keeps shaft in place
and allows easy maintenance (FM version
only)

• Safety reinforced by a secondary water
tightness

• Spline driven one piece shaft connected to
floating disc :

. high reliability of tightness and torque

transmission in the long term.

•

High power transmission with robust grooved
connection between the shaft and the disc.

• Complete protection of the shaft and valve
body from fluids.

• Reliability of movements with self-lubricating
bearings.

• Identification and traceability ensured by

riveted metal tag : see on page 15.

Normalisation

• Design :

According to EN 593 and marking according to EN 19

• European Directive :

Our butterfly valves are in accordance to the safety requirements of the following directive.

:

Directive 2014/68/UE : Equipments under pressure PED

(Pressure Equipment Directive)
Applies to the design, manufacturing and the assessment of the conformity of pressure equipment, the maximum allowable pressure of
which is 0.5 bar.
Pressure equipment for water supply, distribution, and disposal of water is excluded.
Depending on the type of pressure equipment, maximum allowable temperature (PS), DN, physical nature of the fluid (liquid, gas
or vapour) and the degree of danger of the fluid (group1/2)*, the directive classifies this same equipment into different categories
(article 3.3, I, II, III, IV), required for the assessment of conformity with CE marking.
The equipment defined in article 3.3 of the directive must not bear the CE marking.
(*) Group 1 : hazardous fluids (directive 67/548/EEC) / explosive / highly flammable /easily flammable / flammable / very toxic / toxic /

combustion agents.

Group 2 : all other fluids

Important notice : the indicated pressure for the different categories of fluids (L1/L2/G1/G2) is under no condition a guarantee of use.
Therefore, it is essential to validate the use of products under given operating conditions. Socla is not responsible for
alterations of the products to working conditions not previously specified by the customer.
In order to facilitate your choice regarding these new regulatory requirements, Socla has put the necessary information
concerning products with CE marking, specification sheets and product identification plates at your disposal in the price list (+ see additional
explanations on the detachable slip).
In addition, the operating instructions are available on our web site www.socla.com or by simple request from our sales department.

• Iso top connection for actuations :

According to EN ISO 5211

• Face to face :

According to 558-1 series 20
ISO 5752 series 20
API 609 table 2

• Connecting flanges : see on page 10

According to EN1092-1 and EN1092-2
ASME/ANSI B16.5
BS10-d and BS10-e
JIS B2238 and JIS B2239

• Tests :

According to

EN12266-1

Resistance and tightness of the body : test P11(1,5 x allowable operating pressure)
Tightness of the seat : test P12 rate A (1,1 x

Kv = volume of water in m3/h through a valve at a preset

opening stage and under a head loss of 1 bar.

The butterfly valve is not the best product for regula

­ting Nevertheless, the Sylax FM-CNPP butterfly valve
can be used to regulate by an opening stage between
30° and 90°.

A regulation in the opening stage lower than 30° is
not advisable because of over speed, cavitation effect,
which could damage prematurely the valve.

The maximum flow velocity of the fluid through the valve must not exceed :

- 3 m/s for liquid fluids. Between 3 and 5m/s, the use of the Sylax FM-CNPP butterfly valve is possible, but the phenomena of
cavitation, noise, vibration and water hammering increase..

Type of flange

The Sylax FM-CNPP butterfly valve has been
designed to be mounted on standard flanges.
Only standard flanges type 11, 21 and 34
according to EN 1092 are quite compatible.

For other types of flanges, refer to the table
below.
Non appropriate connections will cancel our
guarantee.

NOTE :

The use of expansion seals, as well as the use of elastomer coated flanges, between the flange and the valve are strictly
forbidden.

Installation

• General remarks :

For safety reasons, the installation must take place
under the supervision of authorised people taking
account of local safety instructions and advice.

The handling of butterfly valves and their controls
must be done by staff trained in all technical
aspects of their operation.

Before installation the pipes must be depressurised
and purged (empty of its fluid) in order to avoid
any danger to the operator.

The pipe work must be correctly aligned so that
no extra stress is exerted on the valve casing.

Check the compatibility of the connection flanges
against the operating pressure : the PN number of
the flanges must be greater or equal to the ope­rating pressure.

The valve is a machined piece of equipment and
must not be used to prise apart the flanges.

An instruction notice specifying the installation
characteristics and the commission of the Sylax
FM-CNPP is added to every product. It is available
on our web site www.socla.com or on request
by our sales department.

• Installation conditions :

It is recommended that the distances mentioned
below be respected in order to prolong the life
time of the valve.

Mounting the valve close to pipe work junctions
places it in turbulent zones which increase its
wear.
