A water-abrasive suspension cutting facility includes a pressure tank (11) for providing a water-abrasive agent suspension (13) which is under pressure, a lock chamber (21), and a refilling valve for refilling abrasive agent into the pressure tank via the lock chamber (21). The refilling valve (21) includes a valve entry (49), a valve exit (51), a valve space (71) which is arranged between the valve entry (49) and the valve exit (51), and a valve body (67) which is located in the valve space (71). The valve entry (49) is connected to the lock chamber (21) and the valve exit (51) to the pressure tank (11). The refilling valve (19) can assume a first closure position, a first open position and a second open position. In the first closure position the lock chamber (21) is fluid-separated from the pressure tank.

A valve assembly includes a valve and a valve sensor. The valve includes a solenoid including a core and a coil, and a valve body having a closed state in which fluid is prevented from flowing through the valve body and an open state in which fluid flows through the valve body. The valve sensor detects at least one of the valve body and the coil and causes an alarm to be triggered responsive to not detecting the at least one of the valve body and the coil in a respective target position of the at least one of the valve body and the coil.

A system for delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. An inlet of a manifold is fluidically coupled to a storage tank that contains the fluid to be delivered. A first distal end of a fluid transporting mechanism is fluidically coupled to an outlet of the manifold. A second distal end of the fluid transporting mechanism is fluidically coupled to the fluid tank. A primary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a first fluid level threshold. A secondary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a second fluid level threshold. The first fluid level threshold is lower than the second fluid level threshold.

A valve state grasping system that can be easily retrofitted to any of various existing or operating valves (rotary valves) and actuators, and in particular, even facilities to which commercial power is not supplied, and allows detailed and accurate state grasping and diagnosis or failure prediction for the valve or actuator. The valve state grasping system is configured to perform, based on angular velocity data of a valve stem which opens and closes the valve, state monitoring, diagnosis, and life prediction of this valve. To the valve stem, a monitoring unit having at least a semiconductor-type gyro sensor is attachably and detachably fixed. The angular velocity data includes angular velocity data acquired from this monitoring unit in accordance with a rotational motion of a valve body from being fully open or fully closed to fully closed or fully open.

Provided are an electric valve, a thermal management assembly, and an air conditioning system. The electric valve includes a valve body, a circuit board, and a sensor. The valve body has a passage, and the sensor is connected to the circuit board in at least one of an electric connection mode and a signal connection mode. The sensor is configured to detect at least one of a pressure or a temperature of a working medium in the passage. At least one of the valve body or a housing of the sensor includes a metal portion, and a reference ground of the circuit board is electrically connected directly or indirectly to the metal portion.

A pressure relief valve configured to vent a pressurized tank in the event of a fire is provided. The pressure relief valve includes a body, a vent passage, a plug and a latch. The vent passage is disposed through the body. The vent passage can be placed in fluid communication with an internal volume of a tank and with the atmosphere. The plug is moveably mounted in the vent passage. The latch has a blocking member disposed in contact with a control end of the plug in a first configuration and out of contact with the control end in a second configuration. The second configuration allows movement of the plug in the vent passage. One or both of a shape memory alloy wire and a trigger piston is configured to actuate the latch from the first to the second configuration. The shape memory alloy wire is configured to shorten when exposed to a temperature above a threshold temperature. The trigger piston moves, e.g., by a pressurized gas, in a trigger actuation passage to actuate the latch from the first configuration to the second configuration.

A valve diaphragm includes a flange portion and a diaphragm portion. It is proposed that it includes a data carrier contained in a housing and that the housing is arranged on an edge of the flange portion so as to be at least partially visible when seen from outside onto the edge.

Position transmitter assemblies for use with actuators are disclosed. A position transmitter assembly for use with an actuator stem of an actuator includes a mounting bracket arranged for attachment to the actuator. The position transmitter assembly includes a position transmitter operatively coupled to the mounting bracket, the position transmitter including a position sensor or a feedback array. The position transmitter assembly includes an arm. The arm includes a first portion and a second portion. The other of the feedback array or the position sensor is mounted to the first portion. The position sensor is responsive to the feedback array to enable the position transmitter to determine a position of the actuator. The position transmitter assembly includes a cam assembly arranged between the actuator stem and the arm. The cam assembly is to cause the arm and the feedback array to linearly move when the actuator stem is rotating.

A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories. The system may collect, from the at least one sensor, signals indicative of water usage for substantially all water delivered through the distributed water infrastructure in a time period. The system may construct a plurality of water usage profiles in the aggregate, encompassing substantially all water delivered through the distributed water infrastructure in the time period. The system may assign each constructed water usage profile to one of the plurality of water usage categories. The system may output, for display, water usage for the time period for each of the plurality of water usage categories.
