Why Choose Durco Valves from QRC
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. 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.
At QRC Valves, we are proud to stock and support the full range of Durco plug and butterfly valves. We work closely with clients to understand their process conditions and recommend solutions that balance performance, safety, and cost-efficiency. Whether your system handles aggressive chemicals or requires zero-leakage control, Durco valves provide the durability and reliability you need.

Self-Wiping Plug Sleeve
The self-wiping plug sleeve prevents media buildup on the plug surface, significantly reducing maintenance costs and extending valve life.
In-Line Seal Adjustment
Operators can make quick adjustments using just two external fasteners, hence no need to remove the valve from service.
Precision Sealing
The precision-machined seat and laminated seal ring create uniform seat loading across the sealing surface.
Broad Material Selection
Durco provides one of the widest material portfolios in the valve industry.

Durco TX3 Butterfly Valves
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.
