Air Pressure Regulator Has Large Flow Capabilities

Marsh Bellofram has introduced the Type 78, a direct-acting air pressure regulator designed to offer accurate, large flow and exhaust capabilities within OEM and industrial applications. The Type 78 air pressure regulator is specifically designed for applications that require large flow capabilities and accurate pressure control. Available in five different pressure output ranges of up to 125psig (8.6 bar), this precision regulator offers low droop, high accuracy and fine adjustment sensitivity with maximum supply pressure rated at 400psig (27.6 bar) and achievable flow rates of more than 200 SCFM.

Use of a Bellofram rolling diaphragm provides greater sensitivity and improved accuracy, along with low-friction operation and long useful service life, according to the company. The Type 78 offers a balanced pintle, which minimises output pressure changes caused by fluctuations in supply pressure. The unit can be either pipe or rail mounted. Careful design and use of quality materials in manufacturing the Marsh Bellofram Type 78 air pressure regulator ensures long, trouble-free operation.

In addition, the rugged die-cast zinc and aluminum housings of the Type 78 are pressure tested to assure safe operation and are designed to withstand harsh and abusive environments. This durability is attributed to a chemical conversion coating of all cast components and a vinyl paint finish. Additional optional features and accessories for the Type 78 include low-bleed, non-relieving, square head adjustment, T-handle adjustment, tamper resistant cover, epoxy paint, tapped supply gauge port and tapped exhaust.

Mounting brackets and repair kits are also available. The Marsh Bellofram Type 78 high-pressure air regulator is suitable for use across a variety of industrial applications, including high-flow actuation, high-flow louvers, slitters, rollers and dewinders, high-flow control-loop applications, calibration loops and others.

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.
