AKA Double Pendulum Valve, Double Gate Valve, Double Flap Gate, Double Dump Valves, Tipping valves, Trickle valves - all names used to refer to the product we invented more than 60 years ago. The equipment may go by other names, but there is only one Plattco Double Flap Airlock valve!
The H-Series Premier Valve is the leader in dry material handling valves with thousands of successful applications in industries throughout the world. The H-Series valve is the perfect solution for the most demanding conditions. Customers frequently turn to Plattco when no one else can handle their system's high temperatures and high pressures. Our solutions are customizable and include the options of metal to metal seals, silicone seals, or sacrificial coatings.
The H-Series can handle dry material from fine powders to large, chunky, fibrous pieces. When an application must handle large particle sizes, significant volumes of material (up to 4500 cubic/feet per hour) or the most demanding conditions due to abrasive, corrosive, or sticky characteristics of the material, the H-Series offers a reliable solution that cannot be offered by our competition.
Combined with Plattco’s legendary Easy Maintenance Technology, this exceptional radial valve offers the lowest overall 10 year cost of any other airlock on the market.
