High Temperature and Abrasive Service
From high temperatures to abrasive media or a combination of the two we can supply a wide range of suitable valves.
Specialists in extreme service valves
Once service conditions move outside of the norm for Ball Valves, finding a suitable valve partner can be a problem. From a temperature point of view traditional seat materials can operate between -196°C and around +270°C above that metal seated options allow operation up to @650°C. For abrasive services at low levels PTFE may provide a degree of operability, however metal seated options will give longer lasting performance.

Our Process
We are a problem-solving company, focused on making your projects more efficient, reliable, and cost-effective.
ACV provides a complete, end-to-end solution for valve and automation requirements. From initial project scoping and technical analysis through to final delivery and on-site support, we manage the entire process to reduce risk, simplify procurement, and ensure performance.
Initial enquiry
Our process begins with a detailed customer enquiry, including project scope, specifications, and any known technical requirements. We gather and review all relevant information to determine the most suitable solution for the application.
Quotation
We provide tailored quotations aligned to project complexity, specification, and timescale. Flexible quotation formats streamline customer evaluation and approval, ensuring clarity, consistency, and efficiency throughout the decision-making process.
Stock & Engineering Solutions
Where possible, we supply directly from stock to support fast-track requirements. We can also modify existing stock or source, design, and manufacture solutions to meet specific application needs. Our engineering expertise ensures products are optimised for pressure, temperature, media, and duty requirements while meeting relevant industry standards.
Compliance & Testing
All components undergo rigorous testing in our dedicated facilities to verify performance, integrity, and compliance. Testing regimes are selected to suit the application and may include pressure testing, leak testing, and functional verification to ensure reliability in service.
Order Management
Efficient order management is central to our process. Orders are tracked, coordinated, and fulfilled with care, ensuring correct procedures are followed, milestones are met, and operational integrity is maintained throughout.
Packing & Documentation
Each project is packed in line with customer and project requirements. Full documentation is supplied to support traceability and compliance, including certificates, test reports, and quality documentation as required.

Solving valve challenges in high temperature and abrasion
With valves required to operate under a wide range of Pressures, Temperatures and Media ranging from water to complex mixes of high temperature and entrained solids we can evaluate most applications and recommend the correct valve type, materials and configurations to suit.
Many of the leading Valve manufacturers have deliveries in excess of 26 weeks, some more than 52. At AC Valve Alliance we hold substantial stocks of valves up to 24” and ANSI class 2500 with a variety of end connections with a number of material options. Added to this we have extensive automation and modification facilities backed up with our manufacturing capability.
We have ‘Soft’ Seat and O’Ring options allowing valves to operate at around 300°C. Above this or in services containing solids Metal Seats become necessary these can generally be Tungsten Carbide, Chrome Carbide or cobalt-chromium “superalloys” such as Stellite(tm). There are many other options available which can be selected depending upon precise service conditions.
At minimum, the specifier needs operating and design temperatures, pressure range, service composition (including solids type, size distribution, and loading), required leakage class, cycle frequency, and any code or material restrictions (e.g. cobalt limits, fire‑safe or fugitive emission requirements). With this data, a suitable combination of body material, seat material, coatings, and valve type (ball, gate, globe, butterfly, special ash valve, etc.) can be selected.
