A two chamber regenerative thermal oxidizer has a pair of poppet valves actuated by an eccentric mechanical drive assembly having a single drive shaft. Gas flow through the RTO is reversed by the simultaneous opening and closing of the poppet valves. Deceleration of the valve discs is controlled using a variable speed motor to reduce valve damage. In another configuration, the mechanical eccentric drive controls two sets of butterfly valves in an RTO.
