Features and Advantages
High Pressure, High Temperature, Zero Leakage Butterfly Valves
High-performance butterfly valves (also known as double eccentric butterfly valves) feature an innovative design that provides rugged reliability and extremely easy field maintenance.
The unique, patented design of the McCannalok valve won the Vaaler Best Product Award for Chemical Processing shortly after its introduction. The simple, innovative design provides rugged reliability and extremely easy field maintenance.
GNEE high-performance valves are available to meet your requirements, providing the highest quality and value. After more than 100,000 cycles at 720 psi (49.6 Bar), the seat remains in good condition and continues to provide a bi-directional, zero-leakage seal. Even after more than 878,000 cycles at 2 psi (0.1 Bar), GNEE high-performance valves still provide zero leakage in both directions.
