  • Generating two pneumatic signals to operate an actuator on a valve assembly
    Patent number: 10724555
    Abstract: A controller configured to improve response time on a valve assembly. The controller may have flow modifying structure that couples with a pair of pneumatic outputs, both pneumatically coupled with an actuator on the valve assembly. The flow modifying structure can be configured to convert incoming instrument air into a pair of independent, pneumatic output signals, at least one of which flows directly to the actuator. In one implementation, a volume booster may be used to increase pressure of the other pneumatic output signal upstream of the actuator.
