Iron and Bronze Valves are available in a wide range of sizes and flow rates to cover most applications. The unique design allows a straight flow pattern with low friction loss. A direct sealing diaphragm, the valves only moving part, operates by pipeline or external pressure. Sizes range from 1” to 24” with a variety of control functions and connection options. |
