Durco’s range of non-lubricated and lined plug valves is engineered to meet the toughest chemical and industrial service conditions. These valves are specifically built for environments where corrosive media, abrasive slurries, and tight shutoff are non-negotiable.

Durco Plug Valves

Durco plug valves deliver exceptional reliability due to their robust construction and smart engineering. The self-wiping plug sleeve prevents media buildup on the plug surface, significantly reducing maintenance costs and extending valve life. Moreover, the tapered wedge design ensures a secure, drop-tight seal across both upstream and downstream sides of the valve. This design minimizes the risk of leaks and enhances operational safety.

Another key advantage is that Durco plug valves allow in-line seal adjustments under pressure. Operators can make quick adjustments using just two external fasteners, hence no need to remove the valve from service. Moreover, this feature supports continuous operation and cuts downtime in high-utilization systems.

Durco TX3 – Triple Offset Butterfly Valves for Precision Sealing

The Durco TX3 butterfly valve brings together tight shutoff performance, low torque operation, and exceptional durability. Its triple offset design ensures that the seat and seal never rub during opening or closing. Instead, the valve uses an angular cam motion to minimize wear and maintain a bubble-tight seal, even in gas applications.

The precision-machined seat and laminated seal ring create uniform seat loading across the sealing surface. This not only extends the valve’s service life but also enables bi-directional sealing performance in high-pressure systems.

Broad Material Selection for Specialized Services

Durco provides one of the widest material portfolios in the valve industry. Whether your application involves hydrofluoric acid, oxygen, isocyanates, phosgene, or abrasive slurry media, there is a Durco valve designed to withstand the challenge.

Material options include:

• High-alloy and corrosion-resistant metals.

• PTFE and PFA-lined internals for chemical isolation.

• Configurations for sub-zero, high-pressure, and hazardous fluid systems.
