Plattco Double Flap Airlock Valves - Economically & Operationally Better Than Rotary Valves

Plattco invented the double flap valve in 1958 as a rotary valve alternative. Today, many are purchased in place of rotary valves by bottom-line oriented managers who insist on valves that require less maintenance & improved productivity.

Plattco provides a long-term solution to rotary valve wear and jamming by eliminating the rotary action of other valves. The body of the valve is not a sealing surface.  The seats and flappers, which provide the critical seal, are cast and machined of wear-resistant alloys. They can be replaced quickly and easily without disassembling the valve or taking it out of line, using Plattco’s unique Easy Maintenance Technology.  They are long-life units that are designed to provide many years of maintenance-free service.

Our valve designs eliminate bridging and clogging to maximize operating efficiency. Plattco is the respected leader around the world as the standard for valve excellence
