SIZING &SELECTION

V&A uses sizing and selectionsoftware developed by the valve

manufacturers as well as their ownwhich was developed by specialists to

IEC standards. This service is offered tocustomers to assist in selecting the optimum

valves for the application. These tools significantlyreduce the time required to select and specify the

right valve.

TOTAL COST OF OWNERSHIP

Close working relationships with major production plantsloca l l y , t oge the r w i th g loba l suppor t sys tems has

ensured that V&A technical specialists fully understandT C O p r i n c i p l e s a n d t h e i m p a c t o n t h e e n d u s e r .Recommendations and solutions offered take all knownTCO issues into consideration.

“Optimum solutions,not valves from a catalogue.”

V&A has succeeded in developing technical sales staff into“product and application” specialists, who have a high degreeof expertise within their particular area and are able to offeroptimum solutions, not valves from a catalogue. Thesespecialists are qualified instrument or mechanical technicianshaving spent many years themselves in industry givinga bet ter unders tand ing o f the demands p laced onproduction, project and maintainence personnel.

INTERNATIONAL SUPPLIERRELATIONSHIPS

Outstanding relationships with our global suppliers are key to success - as is being

able to get support globally regardless ofwhere the project may be managed from.

V&A technical specialists regularlyattend advanced product training

internationally.

PROJECTADMINISTRATION

V&A offers project managementsupport that assists you to install andcommission valve packages which is socritical to the success of a project. Thissupport includes project management teams,on-site technical support, document control, criticalcommissioning and start up spares.

PROJECT EXPERIENCE

Significant experience has been gained since 1986 workingwith major companies like Sasol, Sappi, Mondi, Eskom,Fluor, Linde and Uhde to name a few. Projects successfullycompleted by V&A include contracts in excess of R15 millionfor ESD valves for a Sasol gas plant, R26 million worth ofcontracts for ESD valves on a Sasol steam plant and R15 Millionfor ESD valves for a Sasol Ethylene plant. Sappi has awardedcontracts for manual and control valves for various projects tovalues in excess of R100 million. Contracts from Mondi for majorprojects have exceeded R40 million in the last few years. Significantcontracts have also been awarded for pump protection systemsfor Sulzer and KSB for the Eskom power stations.

QUALITY

V&A supplies valve packages that are tested and shipped withthe appropriate test certificates. The quality management systemsof the complete supply chain from global leading valvemanufacturers to V&A and onto the end user are all certifiedto ISO9001:2015.

INTELLIGENT VALVE CONTROLLERS & PST

V&A stocks and supplies intelligent valve positioncontrollers and ESD Partial Stroke Testing units thathelp you realize savings from initial installationthrough to operation simplifying calibrationand diagnostics as well as improvingsafetyperformance and maintenancemanagement. Local facilities areavailable for inspection, testing andrepair where protocols such asPROFIBUS and HART areroutinely handled.

AFTER SALES SERVICE & OEM PARTS

V&A fully understands the need for world classservice and support for production plants.

OEM parts stocked in regional warehouses, V&Acan deliver what is required urgently, minimising

downtime and production losses. Sourcingvalves from our principals internationally is

routinely done as part of our ongoingservice. Thinking globally but acting locallyis part of V&A’s success.

“Thinking globally,acting locally.”

VALVE REPAIRS &RECONDITIONING

Factory accredited facilities areavailable in both Vereenigingand Durban where skilledtechnicians with knowledge andexperience carry out the requiredrepairs and reconditioning usingOEM components.

All final testing is done toappropriate industry and plantstandards.
