Materials

• Refer to page 2

Standard design

• Semi--lug type body (Type 2) with aligment holes allowing
downstream pipe dismantling under PS or dead-- end service

• Extended neck allowing insulation.

• Thermally insulating device for easier fixation of thermal

insulating jacket onto base skirt.

• Elastomerliner: an extra volume of rubber,locatedatthe shaft
passage, provides, by compression between the valve
body and the disc edge, a perfect leak--tightness at the shaft
passages.

• Spherical machined disc ensures perfect upstream/
downstream sealing: zero leakage visible to the naked eye

• Tightness towards the exterior, downstream/upstream
tightness and hydraulic testing in accordance with:
EN 12266--1/leak level A, ISO 5208 category A.

• Face to face dimensions in accordance with:
ISO 5752 -- 20, EN 558-- 1-- 20

• Mounting plate meeting the following standards: ISO 5211.

• Flange connection standard PN 6/10/16

• Marking in accordance EN 19

• Contains no asbestos, CFC, superchlorinated biphenylene,

substances impairing paint wetting.

• Polyurethane paint, 80 µ thickness, colour orange ref.
RAL 2002.

• The valves meet the safety requirements of the pressure
Equipments Directive 97/23/EC (PED) appendix 1 for fluids
of the group 2.

Standard variant

• BOAXMA T--S valves with electrical actuators ACTELEC.

• Washed and packed without substances impairing paint

wetting.

* The indicated weights are those of the valve + the actuator

Installation instructions:

The BOAXMAT--S are factory preset and tested, do not
modify them.
Prior to any actuation, position the valve at mid course,
check its rotation direction and check the stroke limiting
stops for correct operation.
The BERNARD service leaflets as well as the electrical
wiring diagrams are supplied.

Integral protection of the motor is ensured when the
thermal switch included in the winding is properly
connected.

The actuators are disabled by the stroke limiting stops.
The torques limiters on versions AS and BS are safety
contacts.
In case of disturbance, they stop the motor via the control
box and the same time display the problem.
The torques limiters are contacts with a limited usable life.

defined hereafter:

Gas or liquids Liquids*

hazardous** non hazardous** hazardous** non hazardous**

All DN: non allowed

DN ≤ 200: ∆PS = 10 bar max.

DN 250 to 500:

∆PS = 7 bar max.

Upper DN: on request

DN ≤ 200: ∆PS = 10 bar max.

DN 250 to 500:

∆PS = 7 bar max.

Upper DN: on request

DN ≤ 200: ∆PS = 12 bar max.

DN250to500:

∆PS = 7 bar max.

Upper DN: on request

* Liquids having a vapour pressure at the maximum allowable temperature of not more than 0,5 bar above normal atmospheric pressure

1013 mbar .
** Fluids hazardous and not hazardous according to PED.
Nota : A valve fitted at the end of a pipe with a blind flange downstream is not to be considered as an end of pipe service.

The BOAX --- S valve is fitted between pipe flanges by tie--rods, without gasket.
It is bi--directional and can be mounted in all positions.
