Appl. No.:

16/867653

Inventors:

Donald Gross - , US
David Parish - Castlerock CO, US

International Classification:

F16K 31/04
B63B 79/40
F16K 37/00

Abstract:

According to one aspect, a master control module controlling multiple valve assemblies on a marine vessel may include a receiver, an input component, a processor, and a transmitter. The receiver may receive positional status signals from corresponding individual control modules. Each positional status signal may be indicative of a positional status of a valve assembly corresponding to a respective individual control module. The input component may receive a command pertaining to one or more of the valve assemblies, including a desired flow characteristic and/or a desired time. The processor may generate control signals for the valve assemblies in accordance with the desired flow characteristics. The transmitter may transmit the control signals to the respective individual control modules to effectuate the desired flow characteristic accordingly.

Abstract:

An electrically operated valve assembly having a manual override includes a valve body, an actuation cam, a shaft, a gear, and a biasing member. The shaft is connected to the actuation cam and includes a projection. The gear defines an opening which selectively receives the projection of the shaft to engage the shaft to the gear. In a first operating condition of the valve assembly, the actuation cam is in an engaged position relative to the valve and the shaft is biased to be engaged with the gear. In a second operating condition of the valve assembly, the actuation cam is in a disengaged position offset along the axis of the shaft from the valve handle and at least partially rotated about the axis of the shaft such that the shaft is disengaged from the gear. Further, a master control module can control one or more such valve assemblies.
