Frequently Asked Questions

What is an automatic water level control valve?

It's a self-regulating valve that automatically maintains the water level in tanks, reservoirs, or pools by opening to allow water in when the level drops and closing when the tank is full, using a floating ball mechanism.

Can I customize the valve for my project?

Yes. Wiir offers OEM and ODM services. We can customize size, inlet type, material, and branding based on your technical drawings or samples.

Are explosion-proof filters suitable for chemical plants?

Absolutely. Our explosion-proof water filters are designed for high-risk environments and meet safety standards for use in chemical, petrochemical, and industrial facilities.

Do you provide product catalogs and technical drawings?

Yes. Full product catalogs, datasheets, and 2D/3D drawings are available upon request. Visit our official site for downloadable resources.
