Project Supply Chain Management

Our clients view Frenstar as a trusted partner, capable of managing complex valve and actuator projects. Utilising our engineering expertise and wide range of products we can tailor packages to each client’s requirement. Frenstar can manufacture, supply, source, procure and manage valve packages with a driven to deliver approach.

Valve Management

We offer valve and actuator management to our clients. We specialise in providing the correct tailored solution for the project supply of manual and actuated valves. Frenstar manages lead-time projects, and shutdowns and has a large stock holding.


Our industry experience allows us to modify a valve design when required. An example is fabricating and assembling oil-filled or standard valve extension spindles. All calculations and fabrication activities are managed by the Frenstar engineering team.

Project Management


Frenstar provide full in-house valve testing tailored to client specifications, whilst also hosting third party witness inspections as required.


With valves exposed to heavily corrosive conditions and saline environments appropriate coating of the product is key. Frenstar can coat valves to any specification, finish and colour, meeting NACE and NORSOK requirements as required.

Project Management

Our team have dedicated expeditors to aid the management of order progressing and ensure production target milestones are met. We regularly manage large packages for major EPCs / end users and safeguard the on-time supply of all required materials.

For each specific project, we dedicate an in-house focal point Project Manager. With our close communication at kick-off stage we can assess what materials will be available and for items that are outside agreed delivery parameters, recommending suitable alternatives to the client as necessary. For hard-to-find valves that we cannot provide from our large stock inventory, we can use our global strategic partners to fulfil these valve orders.

Frenstar excels with project logistics, customs clearing and managing freight, ensuring delivery is on time, every time. Along with the client, Frenstar will perform a lessons learned analysis as part of our continuous improvement on future projects.
