Tiny actuators with but one moving part
Addressing the large applications gap between macroscopic motors and micro-electromechanical systems, Nanomuscle actuators from Steadlands International (Northumberland, UK) use the properties of shape-memory alloys to create tiny actuators that can be produced at a fraction of the size and cost of traditional electric motors.
Repair service keeps check on fugitive emissions

Sensor gives true valve feedback
Unlike traditional solenoid valves, where an LED signal only indicates the solenoid valve is receiving power, KV’s extension to its range of solenoid valves now provides true positional feedback indicating the valve is actually in its “open” or “closed” position.
Large-diameter influent flow control valve
Red Valve’s full-ported elastomer sleeve of the Series 5400 Influent Flow Control Valve allows for unrestricted flow when open and provides a bi-directional, drop-tight seal when closed.
