Aquaflow Launches Wedge Gate Valve Range

Aquaflow has introduced a range of full-bore metal seat wedge gate valves into its valve portfolio, available from T-T Pumps. The valves, available from DN80 to DN300, meet BS5163:2004 and are suitable for either isolated or buried duty. They withstand a maximum working pressure of 25.0 bar and shell tested to 37.5 bar according to EN12266:2003.

The range has a ductile iron, fusion-bonded epoxy coated (WRAS listed) body, gunmetal seat rings, clockwise-closing stainless steel non-rising spindle, replaceable triple O-ring seals and undrilled body bosses. The standard operation for this range is by either a handwheel or stem cap; however, an ISO5210 pad can be fitted for safe, cost-effective mounting of actuators or gearboxes. Flange connections are to EN1092-2:2002 Table 10, with face-to-face dimensions according to EN558-1:1986 Series 3.

The face-to-face dimension of this range is the same as the PN16 version; therefore it accommodates less room than traditional PN25 gate valves with the longer face-to-face dimension. This new range has a number of associated accessories available for purchase, including: extension spindle; T-key; position indicator; locking device; chainwheel; ISO5210 mounting pad; actuator; and bevel/spur gearboxes.

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.
