Rotork Unveils Rompak Electric Actuators

Rotork has introduced the Rompak range of electric actuators to offer the marine industry a lightweight solution for the operation of quarter-turn valves and dampers. The range is designed to enable shipboard valve functions to be set-up, controlled and monitored with the same degree of accuracy and flexibility as the most up-to-date process systems.

The Rompak actuators retain all the mechanical benefits of the original Rotork Rom design, including self-locking gears, manual override, externally adjustable mechanical stops, a wide range of mains power options and an IP67 watertight enclosure. The Rompak actuator adds a self-contained control package with local controls and status indication relays and the option of Rotork Folomatic positional control, current position transmitter, integral data logger, non-intrusive configuration with a Bluetooth wireless interface and digital bus network connectivity.

Network connectivity, which includes Rotork's dedicated Pakscan and the Profibus, Modbus and Foundation fieldbus open protocols, is also configured by Bluetooth, as is the recovery of historical operating data from the data logger for valve diagnostics and maintenance planning. The three actuator sizes in the Rompak range provide operating torques from 35 to 650Nm and are suitable for ambient temperatures of -5 to +60C. In addition to new installations, the actuators can be retrofit to existing valves using Rotork's Site Services organisation.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
