Tyco Valves & Controls have introduced the Tyco AVID range, a range of control accessories designed to complement the valves and actuators manufactured and marketed by the company. The object is to enable provision of a total, integrated control system from one source. The AVID (Actuator Valve Interface Devices) range incorporates Position Monitors, Analogue (Electro-Pneumatic) and “Smart” Positioners, Control Position Monitors and Network Monitors which interface with the major network protocols. Typical of the advances offered by the AVID range is the “ZR Plus” for the control and position monitoring of automated valves. The “ZRPlus” is a compact, CENELEC-approved package, conforming to IP67 ingress rating and certified for Hazardous Area, Zone 0, 1 and 2 services. The task of calibrating valve positioners has been made easier and safer with the launch of the AVID EaziCal IR range of non-intrusive analogue positioners. Local, manual calibration can be accomplished via the push-button facility of the AutoCal touchpad or by simply implementing an infrared signal from a handheld. Valve usage throughout the process industries is becoming increasingly reliant on electronic network control systems, and the AVID SmartCal intelligent positioner, utilising the HART protocol, provides the basis of diagnostic interpretation of valve performance and status.
