| New Q-5 with NEMA 4 cover  The sturdy Q-5 with NEMA 4 cover from Harwil performs reliably in municipal water supply systems, sewage treatment plants and large-scale irrigation systems. The Q-5 is adaptable to a wide range of pipe sizes and flow rate set points using variable shaft lengths and targets. In the field, set points can be adjusted and targets can be changed. The Q-5SS is designed for mildly corrosive chemicals, oil and acids with its wetted parts of stainless steel and Viton. Both Harwil Q-5s use a 15 amp SPDT switch or can be fitted with a 'dry' circuit SPDT Gold Cross bar switch for computers. Installation can be vertical or horizontal.Harwil is a producer of different switches for modern applications. write your comments about the article :: © 2007 Construction News :: home page |
