Description

The Posi-flate Series 470 High Temperature Butterfly Valve is an elastomeric seated valve capable of providing a bubble-tight seal at temperatures up to 650° F and pressures up to 200 psi. The valve features Posi-flate's unique inflatable seat. This seat uses air pressure to expand the seat against the disc, providing even pressure distribution for a bubble tight seal. The seat makes only casual contact with the disc during opening and closing, eliminating the wear caused by impingement style valves. Substantially less torque is required to open and close the Posi-flate valve compared to other high temperature valves, resulting in a more compact size and lower overall cost Standard sizes range from 2" to 16". The valve materials can be customized to give the best value and performance for an application.
