Where Applied

ASCO valves, supplied by EV Group China, find application in critically important industrial sectors where precise flow control and high reliability are required. In the oil and gas sector, they are used to control the supply of fuel, gases, and other working fluids in drilling rigs, compressor stations, and transportation systems. In the energy sector, ASCO valves are integrated into cooling systems, steam turbines, and power generation units, ensuring safety and efficiency. The food and pharmaceutical industries use our hygienic valves for controlling clean media, ensuring compliance with strict sanitary standards. In water treatment and purification systems, ASCO valves regulate the flows of chemical reagents and purified water, while in HVAC systems, they control refrigerant and air flows to maintain an optimal microclimate.

What to Replace With / Analogues

In case of the need to replace or select analogues for ASCO valves, EV Group China recommends considering products from other leading global manufacturers such as Burkert, Festo, Norgren, or Parker. When choosing an analogue, it is critically important to consider the following parameters: valve type (solenoid, pneumatic, proportional), operating pressure and temperature, type of working medium (aggressiveness, viscosity), required sealing, body and seal material, as well as connection type and supply voltage. For systems with high safety and certification requirements (e.g., ATEX, SIL), it is necessary to ensure that the analogue has the appropriate approvals. Our EV Group China specialists are ready to provide expert support in selecting the optimal solution, considering all technical and economic aspects of the project.

What to Clarify with the Supplier

Before purchasing ASCO valves from a supplier, especially when working with EV Group China, it is recommended to clarify a number of key points to ensure successful project implementation. Firstly, request a complete package of technical documentation, including certificates of conformity (UL, CSA, ATEX, IECEx, RoHS, API), quality passports, and operating instructions. Clarify the exact model marking and serial number, and also confirm the country of origin. It is important to request information on the availability of spare parts and components, as well as the terms of warranty service. For large batches, it is necessary to clarify production and logistics deadlines, as well as the possibility of inspecting products before shipment. It will also be useful to request reference projects or reviews from other clients who have used similar products. EV Group China guarantees full transparency and provides all necessary information for making an informed decision.
