Resilient (Bonded) Seat Centric Wafer Butterfly Valve

Unison Butterfly Valves are designed with strict adherence to material and valve standards. Additionally, we pay careful attention to retrofitting, cost and reliability. Our actuated butterfly valves are life tested for quality assurance. Furthermore, our quality control process has evolved to ensure routine chemical and mechanical checks with complete material tracking.
​
Salient Features:
  • Easy Installation (No additional gaskets required)
  • Designed and tested for long life
  • Interchangeability of parts makes the valve easy to service and diagnose issues
  • Compatibility with multiple flange standards
  • Low-pressure drop across the valve ensures maximum flow and low power requirements
  • High-quality primer and paint for harsh environments (optional)
  • ​Suitable for dead end service
