<p>Switching valve and a regenerative thermal oxidizer (10) including the switching valve (20). The valve of the present invention exhibits excellent sealing characteristics and minimizes wear. The valve (20) has a seal plate (100) that defines two chambers (25), each chamber being a flow port that leads to one of two regenerative beds of the oxidizer (10). The valve also includes a switching flow distributor (50) which provides alternate channeling of the inlet or outlet process gas to each half of the seal plate (100). The valve operates between two modes: a stationary mode and a valve movement mode. In the stationary mode, a tight gas seal is used to minimize or prevent process gas leakage. The gas seal also seals during valve movement.</p> |
