The 253B Exhaust Throttle Valve regulates the removal of gas from a processing system. Its flapper is positioned to modulate gas flow, thereby controlling process pressure. The 253 has a patented non-linear actuator placed between the flapper shaft and the motor drive shaft in order to generate a linear valve transfer characteristic and provide smooth linear pressure control.
