Amiad Filtration Systems added Ooval automatic diaphragm valves to its product lines in the United States and Canada. Amiad has stocked its Oxnard, Calif., warehouse with Ooval valves to serve customers in irrigation, industrial and municipal markets. Ooval valves offer a small environmental footprint, with a design that is intended to reduce head loss for energy savings. The valves are engineered for strength and weight savings, handling pressures up to 230 PSI while using less material in their construction for reduced environmental footprint. Ooval manufactures a range of hydraulically and electrically operated automatic valves, including pressure reducing valves, pressure sustaining valves, pressure-relief valves, remote-control valves and others. All Ooval valves – whether metal or plastic construction – feature the company’s oval design.
