Comeval to attend MMH 2026 – Mining and Minerals Hall

Marina Galindo — Wed, 16 Sep 2026 10:29:01 +0000

The mining sector is evolving towards more efficient, sustainable and safer processes. At Comeval Valve Systems, we remain firmly committed to this transformation. We are therefore delighted to announce our participation in the latest edition of the Mining and Minerals Hall (MMH) in Seville, the leading European mining event of the 21st century, which will take place from 20 to 22 October.

This year, we are attending the event in a very special way. We will be located in Hall 3, Stand 3149–3152, sharing space with Bulnes, an exceptional strategic partner. At this joint exhibition, our technical and sales team will showcase the most advanced range of valve solutions specifically designed to withstand the extreme conditions of the mining industry.

Where can you find us? Hall 3, Stand 3149–3152, Bulnes stand

The transport of laden fluids, heavy slurries and aggressive chemicals demands components of the highest reliability. At our stand, we will be presenting our two key offerings for the sector:

Diaphragm valves: Meticulously designed to isolate the operating mechanism from the fluid. They are the definitive solution for combating severe abrasion and corrosion problems, guaranteeing a complete seal and minimal maintenance.
Ball valves: Robust, with optimised bore sizes that minimise pressure drop and ensure agile and safe flow control in the most critical process lines.

Would you like to be among the first to discover the specialised range of products we’ll be showcasing in Seville?

To ensure you arrive at the trade fair armed with all the key information and can make the most of your visit, we’ll be hosting a free technical webinar on 15 October focused on mining process efficiency. In this webinar, we’ll analyse the engineering behind our diaphragm valves and present real-world success stories. You’ll discover how these solutions mitigate corrosion and abrasion wear, reduce unplanned downtime and maximise your plant’s profitability. What’s more, you’ll be able to discuss any technical queries directly with our specialists before we meet at the MMH.

DIAVAL® Diaphragm Valves: Essential for the Chemical and Mining Industries

Marina Galindo — Wed, 01 Jul 2026 10:50:12 +0000

In process engineering, operational continuity depends directly on the reliability of its components. In highly demanding sectors, DIAVAL® Diaphragm Valves have established themselves as essential solutions for projects in the chemical and mining industries. Their advanced design enables the safe handling of aggressive, corrosive and highly abrasive fluids.

To precisely meet every on-site requirement, the DIAVAL® range is divided into two key configurations, each with very specific technical advantages:

DIAVAL® Corrugated Diaphragm Valves (W Series)

This configuration is specially designed for critical applications and the handling of concentrated chemicals. Its main design benefits include:

- Leak-tight shut-off with less effort: The central vent reduces the diaphragm’s travel, ensuring an immediate leak-tight seal without straining the mechanism.
- Flow regulation capability: Its design allows the handwheel to be positioned at intermediate points for precise flow control.
- Safety with aggressive chemicals.
- Prevent cross-contamination.
- In-line maintenance capability: Thanks to its bolted bonnet, the diaphragm can be replaced without removing the valve from the pipework, minimising downtime.

DIAVAL® Straight-Through Valves (ST Series)

This is the preferred choice when extreme abrasion caused by solids and heavy slurries are a key feature of the production process. It stands out for the following advantages:

- Zero blockages: When fully open, the body behaves like a continuous straight pipe, preventing pressure drops or the risk of blockages in viscous fluids.
- Less abrasive wear: Solids, sand and sludge flow straight through without striking internal bends directly, extending the equipment’s service life.
- Direct mechanical cleaning: Its completely straight geometry allows internal cleaning systems to be inserted easily.
- Perfect bidirectional flow: It guarantees optimal shut-off performance regardless of the direction of fluid flow.

Optimise your plant with COMEVAL®

Choosing the right diaphragm technology makes the difference between an unplanned shutdown and a profitable process. At COMEVAL VALVE SYSTEMS, we help you integrate the exact model required by your technical infrastructure. Do you have a new project underway?
