General information

The concentric flanged butterfly valves 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 sewage 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.

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

Traceability

Traceability system for LUG 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.

Marking (identification/labels)

Hydraulic characteristics

Headloss Δp inside the valve is expressed with the flow coefficient Kv which is the flow going through the valve at a temperature 20ºC and generating a headloss of 1 bar.

For the water we obtain the simplified calculation below:

Kv = Q ∆P

with Q in m³/h and Kv in m³/h, Δp in bar

Flow coefficient Kv (in m3/h) according to the opening angle of the disc:

Operating with MN and MR type hand lever

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

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

The MR type is a 0° to 90° regulation hand lever. This product is not referenced in our range, please consult us.
