Kinetrol spring return units

5 December 2016

Spiral torsion springs are found in many places like the clocks, watches, timers. The new Kinetrol spring return units are capable of storing much more energy than a typical compression spring, and working in smaller, more compact packages, spiral torsion springs for valve and damper actuation are a proven step-up over helical compression springs.

AS Interface for Kinetrol Vane Actuators

28 November 2016

Devices conforming to the AS interface (Actuator Sensor interface) set of open specifications are used to make up control systems based on a two-wire communication cable known as a bus. Up to 31 actuators and sensors (“slaves”) can be connected to the AS interface bus, and can be controlled or monitored by means of a digital signal sent via the bus to and from a “master” device (which can be a computer or a PLC).
