When you're on a job, the last thing you need is a component that lets you down. You need reliable, robust parts that fit right the first time and provide long-lasting performance. This WRAS-approved industrial butterfly valve is designed for exactly that, giving you the confidence and control required for any professional heating, ventilation, or water system installation.

Total Control and Unbeatable Reliability

In professional systems where failure isn't an option, the 3 ART 135 Lug Tap WRASBFly EPDM Liner DI Body 316SS Disc delivers the robust performance you need. It's more than just a component; it’s a guarantee of quality that ensures your installations run smoothly from day one. For large-scale HVAC projects, potable water mains, or industrial process lines, this valve provides the precision and peace of mind that comes from using a part built for the toughest conditions. It’s the kind of fit-and-forget reliability that professionals, from established firms like Andrews to fast-growing start-ups, depend on.

Exceptional Durability for Demanding Environments

The exceptional durability starts with its materials. The body is constructed from tough Ductile Iron (DI), giving it the strength to handle high-pressure environments without issue. Inside, the 316 Stainless Steel disc offers superior resistance to corrosion and chemical wear, far outlasting lesser alternatives. This is critical in closed-loop Heating systems where treated water can be aggressive over time. This is all sealed by a high-grade EPDM (Ethylene Propylene Diene Monomer) liner, which ensures a bubble-tight, leak-proof closure time after time. These aren't just technical terms; they are the markers of a valve that prevents costly call-backs and keeps your clients happy. Its WRAS approval is a crucial certification, making it a legal and safe choice for any application involving potable water, from public buildings to new housing developments.

Designed for the Professional Installer

Beyond its tough construction, this industrial butterfly valve is designed with the installer in mind. The lugged and tapped body is a key feature, allowing for end-of-line servicing. This means you can perform maintenance on a pump or filter without needing to drain the entire system, which is a massive time-saver on any job. The direct-mount ISO 5211 pad makes it incredibly versatile, ready for anything from a simple lever to a fully automated electric or pneumatic actuator from brands like EPH Controls. This adaptability makes it a cornerstone of our Plumbing supplies and works perfectly alongside high-performance Pumps from specialists like Grundfos.
