Ecco/Gregory has provided knife gate valves to local customers since 1980. This includes applications in the following industries; pulp and paper, power, chemical, petrochemical, materials handling and conveying as well as with various OEM's.
Recently we were asked to quote on a requirement which included the following components; air cylinder actuated valves, solenoid, target limit switches with AS-Interface communication including junction boxes for termination of all wiring. We were awarded an order for a mix of 22 round and square ported valves for dry material conveying and silo shutoff services. All of the valves required bi-directional seating capability. The valves ranged in sizes of 3" - 6" for round and 15" to 24" for square.
