Abstract
A shut off valve featuring a flow conduit with a fluid inflow end and a fluid outflow end, at least one electrically actuated flow control element coupled to the conduit with a blocking state and a flow state, control circuits coupled to the element and a local power source coupled at least to the control circuits. Wherein, in response to a received signal from a displaced source, the control circuits switch the element from the flow state to the blocking state.
Claims33
A shut off valve comprising:
- a flow conduit with a fluid inflow end and a fluid outflow end;
- at least one electrically actuated flow control element coupled to the conduit with a blocking state and a flow state;
- control circuits coupled to the element;

A shut off valve comprising:
- a flow conduit with a fluid inflow end and a fluid outflow end, the flow conduit having an interior channel suitable for carrying liquid;
- a plurality of electrically actuated flow control elements coupled to the conduit between the fluid inflow and fluid outflow ends, the flow control elements having a blocking state and a flow state;
- control circuits coupled to the plurality of elements;
- at least one of a flow meter, or, a differential pressure sensor affixed to the conduit between the fluid inflow and fluid outflow ends and electrically coupled to the control circuits;
- at least one of a wired, or a wireless communications interface coupled to the control circuits;
- a fluid driven generator affixed to the conduit between the fluid inflow and fluid outflow ends;
- and
- a rechargeable battery proximate the control circuits, the battery electrically coupled to the fluid driven generator and control circuits, wherein in response to a received signal, from a displaced source, the control circuits switch the element from the flow state to the blocking state.
