16"-60" Resilient Wedge Gate Valves with Flex-Ring Ends - Spur Gear Actuator Flex-Ring
AMERICAN’s 16"-60" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems. These valves have a rated working pressure of 250 psig with zero leakage. The waterway is clear and unobstructed.
The Flex-Ring design incorporates the following exclusive design features:
Positive joint restraint
No need for friction style restrainers
No point loading of pipe wall
No restraint hardware to corrode
Additional joint deflection compared to traditional pipe joints
Even distribution of pipeline thrust loads
Joint restraint hardware is protected inside the valve joint
Advantages Over Standard Butterfly Valve Designs
No disc in waterway to restrict flow or to increase pumping costs
Allows passage of pigging devices
Internal parts can be serviced without cutting valve out of pipeline
250 psig rating provides for future pressure increases over the 150 psig pressure rating typically found on most butterfly valves
