D71X Wafer Butterfly Valve
Compact & Lightweight for Fast Installation
Wafertype design is sandwiched between two flanges, reducing material and space requirements; ideal for tight installations.
Quarter-Turn Operation for Quick Actuation
The disc rotates just 90° to move from open to closed, enabling rapid response and efficient flow control.
Low Pressure Drop & Full Bore Design for High Efficiency
Designed for full bore, free-flow passage with no hollow cavities to trap debris, ensuring low pressure loss and hygienic performance.
Bi-Directional Sealing & Multi-Media Compatibility
Often designed for bi-directional sealing, these valves handle a wide range of media including water, gas and chemical fluids.
Cost-Effective & Easy Maintenance
With fewer components and simpler installation, wafer butterfly valves offer excellent value and lower lifecycle maintenance costs.
