Eliminate production inefficiencies and frequent valve maintenance with the patent-pending Quantum Series Orifice Gate, a leading edge valve designed specifically to handle dry bulk solids in gravity flow, dilute phase, or vacuum conveying up to 15 psig (1 bar), depending on size and modifications. Quantum Series Orifice Gate valves feature a full-flange, weather-resistant design with improved sealing performance, higher durability, easier maintenance, and fewer replacement parts. Sizes for the Vortex Quantum Series Orifice Gate range from 2 inches to 14 inches. Traditional knife gates or butterfly valves are designed to handle gases and liquids, and not dry materials. These valves rely on soft rubber seals that erode or tear away during use, allowing leakage of air and material through the valve and into the atmosphere. The Quantum Series Orifice Gate is designed to eliminate these problems. The Quantum Orifice Gate’s blade and seal design allows the valve to self-clean on the opening stroke, which prevents material from packing on the valve’s internal seals. This feature is critical to maintain cleanliness and inhibit material leakage across the valve or into the atmosphere.
