BUTTERFLY VALVES

Concentric Double Flanged Butterfly Valve Series S20 DN80-1600

Product family
Valves

General information

The concentric double flanged butterfly valves series S20 have been designed, generally, for industrial applications where dimensional problems are important.

Their bolting design, on both sides, allows the dismantling of only one part of the installation while maintaining the other one under pressure and operational. They also facilitate the assemblies requiring a temporary isolation of some parts of the network in settlements such as pumping stations, warehouses, naval installations, etc.

Field of use

Different materials and coatings used for butterfly valves and liners can have a large response to many situations in the industrial area of drinking water and other fluids as the raw water, sea water, etc.

It provides an effective and reliable solution in conditions of work as may be pumping stations, water treatment, desalination, irrigation, etc.

DN40–600 - Operation by hand lever type MN and MR

 The operation by hand lever allows the disc between 0 and 90°. There are two types of manual control lever, the MN type and type MR.

MN type is the referenced for our range of Wafer and Lug valves. The lever allows seven positions of the butterfly between 0° to 90° with anchorage by spring.

Added values

A) Bushings

They ensure alignment of the shafts as well as reducing the torque.

Together with the shaft packing give additional safety preventing internal leakage and external contamination.

B) Body design

The long-neck construction allows easy installation and provision for insulation, even if the valves are assembled between flanges.

The top and bottom alignment lugs make mounting between DIN-ANSI-JIS, etc., flanges very easy.

C) Spherical disc

The disc edge in contact with the seat is completely spherical providing smooth operation and considerable reduction of the valve torque.

The combination of the valve tightness and reduced friction, especially around the shafts, gives a three folds increase in the life span of the seat

D) Interchangeability

All valve components can be dismantled and the replaceable parts are interchangeable with concentric flanged butterfly valves.

Compliance with standards

Company: designer and manufacturer works according to ISO 9001 by AENOR n° ES 0780 / 1997

Product: complies to the NF EN1074-1 and DVGW standards (up to DN700). Rest of the range in process.

Dimensions :

NF EN 593: Metallic butterfly valves

NF EN 558-1: Face to Face dimensions series 20

EN ISO 5752: Metal valves for flanged pipe network. Table 5 short series

API 609: Butterfly valves Flanged, Lugged and Wafer

NF EN 1092-2: Flange connections to the piping material

Materials: NF EN1503: Valves. Materials for bodies, bonnets and covers

Operation:

EN ISO 5210 : Multi-turn actuator to valve

EN ISO 5211 : Part-turn actuator to valve

Assembling between flanges: ISO PN10 or PN16, DIN 2632 PN10 or PN16, EN-1092 PN10 or PN16, NFE 29222 PN10 or PN16

Identification : EN ISO 5209: Marking

Hydraulic Tests:

EN ISO 5208: Pressure (Ratio A-No leakage)

EN 12 266-1: Sealing (Ratio A-No leakage)

Drinking water approvals : ACS for all the valves from DN32 up to DN900 mm according to the order from May 29th 1997 amended by the circular from the French Ministry of Health DGS/SD7 A 2002 n° 571 and dated from November 25th 2002.

In accordance with the German rules DVGW n° 6201CM0237.

Traceability

Traceability system for Concentric double flanged butterfly valves allows since the departure from the factory to the last day of life of the valve to obtain information relating to the product origin and quality both of coatings and materials, manufacturing, inspection and hydraulic tests results.

From the moment the order is in the computer system, starts the program of manufacturing. A serial number is automatically assigned to this valve. Manufacturing sheet will be marked with this number. This sheet will contain all information about manufacture and inspection of the valve. At the end, two stickers with the number of identification will be placed in the body and in the top flange of the valve.

Assembling

The trial sheet assembly is identified with the internal number. This sheet has as many labels as valves to assemble. This label identifies the person responsible for the mounting and the possible problems during the assembling. The document contains the components of the valve if certification 3.1 is required by the customer.

Hydraulic tests

Label identifying the inspector and the results of the tests. Any remark produced during the tests and the torque is shown.

Foundry marking

Body and disc: manufacturer and type of material.
