Introduction of Metal Seal Butterfly Valve
The design of the provides a non-rubbing, open/close operation. Unlike conventional butterfly and gate valves, whose seats are chafed with every stroke, uses a triple offset design to prevent seat wear. This means superior performance, lower maintenance, and a longer life for your valves. The versatility of the design allows for use in large variety of applications and within a broad range of operating temperatures.
