1. General Terms

This instruction manual applies for DELTA DA3 plus double seat

valves in the nominal dimensions DN 40-100, 1,5"-4" for use in

specific ATEX applications (according to Directive 2014/34/EU).

The valve must only be assembbled, disassembled and

reassembled by persons who have been trained in APV valves or by

SPX FLOW service team members. If necessary, contact

your local SPX FLOW representative.

This instruction manual must be read and observed by the

responsible operating and maintenance personnel.

We point out that we will not accept any liability for damage or

malfunctions resulting from the non-compliance with this instruction

manual.

Descriptions and data given herein are subject to technical changes.

1.1.Symbols

This symbol draws your attention to important directions which have

to be observed with regard to the operation in explosive areas.

This technical safety symbol draws your attention to important

directions for operating safety. You will find it wherever the activities

described are bearing health hazards or risks for persons or

material assets.

1.2.ResponsibilityforATEXcertification-scopeofsupply

SPX FLOW will be held responsible only for the valves supplied and

selected according to the operating conditions indicated by the

customer or end user and as stated in the order confirmation. If in

doubt, contact your local supplier.

All other assembled equipment and devices must have a separate

certification of at least the same or higher grade of protection

as the valve, provided by the supplier(s) of that equipment and

devices. The complete unit must be certified separately by the final

assembling manufacturer and must have a separate name plate

supplied by the unit manufacturer.

2. Safety Instructions

Danger!

Ifthevalveisusedforammableliquids,itmustbeobserved

that every operation of the valve is combined with an operating

leakage of about 4.0 ml.

The operator shall consider these conditions in his considerations

andclassicationsofexplosiveenvironments.

- Regular maintenance including the replacement of all seals and

bearing bushes must be scheduled in order to prevent leakages and

discharge of liquids.

- Connections which are not used must be sealed by a plug.

- Safe discharge of the cleaning liquids must be ensured!

- Before any maintenance work the line system must be

depressurized and drained if possible.

- Separate all electric and pneumatic connections.

- Observe the following Service Instructions to ensure safe

maintenance of the valve.

Danger!

Welded actuators are preloaded by spring force.

Openingoftheactuatorsisstrictlyforbidden.

Dangertolife!

Actuators which are no longer used or defective must be diposed in

professional manner.

Defective actuators must be returned to your SPX FLOW

representative for their professional disposal and free of charge for

you.

Please address to your local SPX FLOW representative.

2. Safety Instructions

Installation, connection, start-up, maintenance and repair work must

onlybecarriedoutbyqualiedpersonnel.

The following aspects must be observed:

- The instructions of this manual together with all relevant instructions

for the components, equipment and installations installed.

- Warningsandinstallationsxedtothecomponents.

- Thespecicregulationsforandrequirementstothesysteminwhich

the valve is installed.

- The currently valid regional, national and international regulations.

- Any special requirement and national legislation relative to the use

ofammableliquidsortools,e.g.theriskofignitionincaseofspark

formation, must be observed.

It must be ensured that the group, the category and the temperature

class of the valve complies with the minimum requirements of the

operating environment!

Inammablegasmixturesordustconcentrationsinconnectionwith

hot, operational and movable parts of the valve can lead to serious

or fatal injury!

Before start of assembly the operator must make sure that an

explosive atmosphere does not exist (detection/measurement of

potential concentration of hazardous substances).

Conductive connection to the pipeline must be provided.

The integration into the internal potential equalisation must be

guaranteed!

The APV CU2, CU3 and CU4 Control Units are not suited for use

in ATEX environments!

Under standard operating conditions the highest surface

temperature will be comparably as high as the temperature of the

medium plus a safety addition for local temperature increases. The

valve must be completely free to the environment in order to provide

 forsufcientheatrelease.

All data (temperature classes) refer to an ambient temperature

of 0°C and 40°C. If the ambient temperature is above 40°C, the

temperature difference must be adjusted. In all cases, contact your

responsible SPX FLOW representative!
