Diaphragm valves have proven to be the ideal solution for many of the most common challenges faced by process engineers, combining reliability with controlled ownership costs. With a simple and reliable design, diaphragm valves provide safe, fully leak-tight operation at the plant. Furthermore, their maintenance, when necessary, is limited to the replacement of the diaphragm.…
At COMEVAL VALVE SYSTEMS, we understand that accurate dimensioning and proper implementation are essential for the success of every project. That’s why we use advanced sizing software, such as ARI-myValve, combined with the expertise of our engineering team to deliver tailored valve solutions for each specific application. Our experienced engineers actively contribute to the engineering…
At COMEVAL VALVE SYSTEMS, every batch of components undergoes strict inspection before entering the assembly line. This new batch of components for UNIWAT® 504 gate valves has just been released after successfully passing visual and dimensional inspection, ensuring compliance with our quality standards and technical tolerances. It’s all part of our ongoing commitment to reliability,…
At our facilities, each assembly undergoes functional and pressure testing to ensure proper performance and complete leak-tightness before dispatch. At COMEVAL, we maintain a comprehensive stock of components — bodies, diaphragms, compressors, stems, actuators, and coupling systems — ready for fast assembly across a wide range of combinations, precisely tailored to meet the specific demands…
At DIAVAL®, we pursue excellence through strict quality control at every stage of manufacturing — from material selection and machining to assembly and final inspection. Each diaphragm valve is subject to functional and pressure testing that exceeds industry standards, ensuring long-term reliability and performance under demanding conditions. Want to know more?

We have recently completed the shipment of a new ARI flash tank for an aeronautical industry project in Madrid. Following ARI’s line regarding energy reuse, this tank recovers energy from the process that converts the condensate into flash steam, thus utilizing the temperature of the hot condensate, resulting in energy and economic savings. In this…
Diaval diaphragm valves are the ideal problem solver for the chemical and mining industries. Their high resistance to corrosive and abrasive liquids, thanks to the ability to apply coatings, makes them a mainstay of every industry in these sectors. To guarantee the success of the operations to be carried out, we apply exhaustive resistance controls.…
There are many special features of #Diaval valves that make them suitable for many scenarios. One reason to choose Diaval diaphragm valves is the dynamism they offer when it comes to applying refills. At Comeval we readjust valves to suit new conditions, Diaval valves make this task very simple and the installation of these involves…
We have recently completed the delivery of a Uniwat® plunger control valve, characterised by its compact construction, precise design and control behaviour. For a water distribution project in Saudi Arabia, our Uniwat valve with its axial flow generates low torque, low flow turbulence avoiding cavitation and managing large volume flow making it the ideal choice…
When delivering our products, we adapt to all the tests requested by engineering companies, with hydrostatic testing being a key step in the whole programme of inspection points. In this case, for the recently announced North African desalination plant project, we used our in-house test bench to ensure the pressure resistance of all valves supplied.…
