Control Valves Simplify Hydraulic Operations

Parker Hannifin has launched a series of proportional directional control valves featuring integrated electronics, designed to simplify hydraulic operations. The D*FB series valves, which are said to be simple to install, are intended to help both original equipment manufacturers and end users to improve productivity and profitability. The built-in electronics lower manufacturing tolerances while ensuring that all valves perform identically in serial applications.

This makes the replacement of a valve in the middle of a night shift, for instance, a simple operation. The D*FB valves are supplied with preset factory parameter values, which can be modified via the onboard electronics using Parker's free-of-charge ProPxD software. The software makes it simple to change, store and load parameter settings to any number of valves or return to the default settings with one click of the mouse.

The ProPxD software also incorporates a basic diagnostic function for additional data analyses and offers users the benefits of simple configuration and less downtime through the copy-and-paste function for parameter sets, according to the company. Controlled by external electronics, the hydraulic performance of the D*FB valves is said to provide low hysteresis and high repeatability. Available with a spool/sleeve or a spool/body design, the D*FB valves are sized NG06 (CETOP03) and NG10 (CETOP05) and operate off command signals of +/-10VDC or 4-20mA. The new valves are backed by Parker's global network of manufacturing, sales and customer support centres.

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.
