General information

Non flanged LUG butterfly valves have been designed, generally, for industrial applications where dimensional problems are important.

The LUG butterfly valve is connected to flanged pieces of the network by means of screws located on each side of the valve and which are screwed in the tapped/threaded parts body of the valve. This design allows removal of one side of the installation while the other side is under pressure. It offers easy assembling in facilities where temporary line isolation is necessary: pump outputs, tanks, boat hulls, 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 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.

No flanged joint must be installed on this valve. The concentric valves should not be assembled with large tolerance flange adapters (type Ultraquick).

Added values

A) Bushings

Bushings 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 is 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 butterfly valve type.

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.

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.

Screw for fixed flange and mobile flange

The table below presents the name and the type of screws to use depending on the type of flange. SGPAM works with two types of flanges: fix and mobile.

The number of screws is given by flange unit, so to set the total number of screws is the sum of the two flanges. The information in the table is given for a single flange.

Three cases must be considered:

  • Two fix flanges
  • Two adjustable clamps
  • One flange fix and one adjustable
