    Abstract: A servo valve comprising first and second nozzles and first and second piezoelectric actuators arranged to control fluid flow through the first and second nozzles respectively. A first fluid flow path is defined between the first nozzle and the first piezoelectric actuator and a second fluid flow path is defined between the second nozzle and the second piezoelectric actuator. The first and second piezoelectric actuators are arranged such that applying a voltage to the first and second piezoelectric actuators causes a change in dimension thereof, which acts to open or restrict said first and second fluid flow paths respectively.

    Abstract: A pendulum-type electromagnetic actuator is provided. The actuator includes a curved stationary member comprising a stationary core and a winding wound about the stationary core. A first moving member includes a first moving core and a first plurality of permanent magnets attached to the first moving core, the first moving member is curved and positioned on a first side of the stationary member. A second moving member includes a second moving core and a second plurality of permanent magnets attached to the second moving core, the second moving member is curved and position on a second side of the stationary member, the second side opposite the first side. The actuator further includes a pivot and a pivot connector connecting at least one of the first moving member and the second moving member to the pivot such that the curved moving member rotates about the pivot.

    Abstract: The subject matter of this specification can be embodied in, among other things, an apparatus that includes a valve with a valve housing having an axial bore, a first inlet port, a first outlet port, and a piston located within the axial bore and having a first fluid passage and configured to allow reciprocal axial movement of the piston within the axial bore between a first position in which the first fluid passage aligns axially with the first inlet port and the first outlet port to form a first fluidic circuit, and a second position in which the piston blocks at least one of the first inlet port and the first outlet port. The apparatus also includes a lockout assembly configurable to fix the piston into a selected position in a first configuration, and not interfere with reciprocal axial movement of the piston in a second configuration.

    Abstract: The disclosure relates to a method for operation of a position regulator for control of a pneumatic drive for an actuating member in a process installation. The position regulator has a pneumatic system with at least one nozzle/bounce-plate system, in which the bounce plates are in the form of piezo bending bars. For damped ventilation and venting of the pneumatic drive in the event of failure of the electrical power, it is proposed that the level of the electrical power supply be monitored and that, if a predeterminable limit value is undershot, the piezo bending bars of the pneumatics are adjusted via the input signals of the pneumatics such that the pneumatically controlled valves, which are subject to a characteristic, of the amplifier are open precisely just so far that a damped movement of the pneumatic actuating drive takes place to a predeterminable limit position at the desired movement speed.
