Near Intersection of I-35 & I-90 Southern Mn. | Failure with the 3/4" control valve. This is just a modified 3/4" control valve that they used with their manual systems for years and put in limit switches for auto systems.
The 1" size is what I've always used personally with good results and reliability. The 1" control valve should take about 8 seconds to go from fully closed to fully open. The 1" valve does not go completely wide open as the last bit of travel would not change the flow much anyway. |
