Welcome to Plattco see our Double flap valves and Slidegates
Plattco Double Flap Airlock Valves are economically and operationally better then rotary valves.
Plattco invented the double flap valve in 1958 as a alternative to the rotary valve. Today, many are purchased in place of rotary valves by bottom-line oriented managers who insist on valves that require less maintenance & improved productivity.
Our products provide 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 part of the seal allowing for decades of use. The seat and flapper, which provide the critical seal, are cast and machined of wear-resistant alloys and can be replaced quickly and easily without disassembling the valve or taking it out of line. Designed to provide many years of maintenance-free service.
The Plattco valve design eliminates bridging and clogging to maximize operating efficiency.
