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 butterfly valves Wafer type.

Traceability

Traceability system for WAFER 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.

Pneumatic actuator mechanism for Wafer and Lug Butterfly Valves

The fluid used in pneumatic position indicators can be water, air or any other non-corrosive fluid. Compressed air is generally used at a maximum supply pressure of 8 bar and a temperature ranging from -32°C to +90°C. The air acts on a piston. The movement of this piston causes a threaded rod to move longitudinally.
 
There are two models : the « PA » type and the « P » type.
 
"PA" type actuator mechanisms are composed of pre-compressed springs with a single spring safety system. The number of springs on each side can vary from 2 to 6 springs depending on the operating torque requirements. Easy to assemble and replace.
 
"P" type actuator mechanisms are composed of two concentric springs on each side. The safety system is optional. There is no initial pre-compression, which makes assembling and replacing the springs less straightforward.
 
There are two possible operating modes for a pneumatic actuator mechanism: single effect (spring return) and double effect, with torques ranging from 15 Nm to 5,000 Nm.


Single effect consists of a single chamber with a piston plus a mechanical spring. Air pressure moves the piston and compresses the spring. In the event of air failure, the spring returns the piston to its original position.


Double effect consists of two chambers. In the event of air failure, the piston remains in its final position.
