Valin's in-house control panel shop is UL 508A certified and can custom build panels from the ground up, or bring existing control panels up to UL safety standards. Our panels are constructed with field serviceability in mind, using only top of the line components. Each panel is custom designed, well documented and aesthetically pleasing.
A UL 508a certification is an industrial control panel directive, which electrical inspectors look for. The UL Listing Mark on an industrial control panel provides evidence of third party certification to the municipal inspection authority that the panel complies with an acceptable safety standard. The Listing Mark may be applied to a wide variety of designs -- ranging from custom built, one designs with only minor variations. UL is the trusted source across the globe for product compliance. Benefiting a range of customers and regulating bodies - UL has tested products for public safety for more than a century.
The UL Mark is one of the most recognized, accepted and trusted symbols in the world. It means that a not-for-profit, independent laboratory has tested samples of products to safety requirements and conducts periodic checks of manufacturers' facilities. It says something about the equipment you use; it's your one assurance that steps have been taken in the interest of safety.
