Streamlined Flow Control: The Quarter-Turn Advantage
When system footprint and operational speed are the primary engineering constraints, Veyron Valve’s Manual Butterfly Valve is the definitive alternative to traditional gate valves. Designed for both isolation and basic throttling, this valve operates on a "Quarter-Turn" (90-degree) logic, allowing operators to achieve full-shutoff or full-flow in seconds. Its compact, lightweight profile significantly reduces the mechanical load on the piping structure, making it the preferred choice for large-diameter HVAC, water treatment, and industrial cooling loops.
Sealing Integrity: The Resilient Interface
The core reliability of our butterfly valve series is centered on the Concentric Design. The valve stem, disc, and seat are all precisely aligned on a single axis.
- Bi-directional Sealing: Unlike some high-performance offsets, our resilient-seated concentric valves provide a "bubble-tight" seal in both flow directions. This allows for total flexibility during field installation, as the valve remains effective regardless of the media’s direction.
- The Dry-Stem Design: We utilize a multi-layered sealing system around the stem to ensure a "dry-stem" operation. The process media never contacts the stem or the bushings, preventing the localized corrosion and "stem freezing" that often lead to actuator failure in lower-grade designs.
- Interchangeable Seats: Our seats are available in EPDM, NBR, or PTFE, depending on the chemical nature of the fluid. The seat is precision-molded to provide a primary seal against the disc and a secondary seal against the pipe flanges, eliminating the need for additional flange gaskets.

Engineered for Operators
Veyron Valve prioritizes ergonomic handling. For valves up to DN250, we provide a Heavy-Duty Notch Plate Lever with a locking mechanism, allowing for precise 10-degree increment throttling. For larger diameters, we utilize Weather-Proof Worm Gearboxes that offer a high mechanical advantage, ensuring that even under maximum differential pressure, the valve can be operated with minimal manual torque.
