Abstract: A fail-freeze valve positioner system is disclosed. The system has a transducer with a first type output port connectible to a valve actuator, and a second type input port receptive to a valve position signal that is proportional to an output of the first type output port. In addition, the system has a monitoring circuit that generates a pilot activation signal while predefined conditions are met. A primary piloted valve in communication with the monitoring circuit is coupled to the first valve. The first type output port is disconnected from the valve actuator while the pilot activation signal and thus the first valve are deactivated, holding the valve actuator in place.

Abstract: A booster valve comprising a housing having a signal port, an actuator port, a supply port, and an exhaust port disposed therein. Disposed within the housing are upper and lower plugs. The upper and lower plugs and the housing collectively define a signal chamber which fluidly communicates with the signal port, an actuator chamber which fluidly communicates with the actuator port, and a supply chamber which fluidly communicates with the supply port. The upper and lower plugs are selectively moveable between neutral, delivery and discharge positions. When in the neutral position, the actuator chamber is fluidly isolated from both the supply chamber and the exhaust port. When in the delivery position, the actuator chamber fluidly communicates with the supply chamber but is fluidly isolated from the exhaust port. Finally, when in the discharge position, the actuator chamber fluidly communicates with the exhaust port but is fluidly isolated from the supply chamber.

Abstract translation: 一种增压阀，包括具有设置在其中的信号端口，致动器端口，供给端口和排气口的壳体。 设置在外壳内的是上下插头。 上，下插头和壳体共同限定了与信号端口流体连通的信号室，与致动器端口流体连通的致动器室和与供应端口流体连通的供应室。 上部和下部插塞可选择性地在中性点，输送位置和放电位置之间移动。 当处于中立位置时，致动器室与供应室和排气口都是流体隔离的。 当在输送位置时，致动器室与供应室流体连通，但与排气口流体隔离。 最后，当处于排出位置时，致动器室与排气口流体连通，但与供给室流体隔离。
