Diaphragm Valves for Use with Aggressive Chemicals

Burkert has launched a range of PFA-lined stainless steel diaphragm valves for use with aggressive chemicals, suitable for hygienic processing applications in food, pharmaceuticals and biotechnology. The new range forms part of the company's BBS range of stainless steel products. The PFA liner integrated into the new diaphragm valves is a fluoropolymer that offers users the benefits of similar chemical resistance to PTFE against most aggressive chemicals and acids, but with lower levels of porosity.

It is also tolerant of higher temperatures, with the capability for operation up to 260C. The new diaphragm valves complement Burkert's existing BBS range of sterile ancillary piping, flanges, connectors, indicators, sampling systems and vessel equipment. They are designed to provide a synergy with Burkert's valve, sensor, process control, hazardous area and specialist products, enabling the company to go further down the systems route in providing customised hygienic processing solutions to the high-technology pharmaceutical and biotechnology sectors.

In these demanding sectors, where compactness, smart communications, plant footprints, cleaning and sterilisation, dead legs, cross contamination and validation are everyday concerns, the BBS products deliver higher process efficiency and higher yields by offering unlimited process modularity. Where Burkert links all parts of the production process, via its valve process control and fieldbus products, BBS links them all mechanically, with sterile weld unions, quick connects, flanges, fittings, hoses and pipes.

In addition, to provide complete processing solutions, these products are complemented by special valves, sampling systems, flow indicators and heat exchangers. From the control room to the downstream processing area, through to the plant's utilities services, the scope of systems and components from Burkert/BBS covers all the different application environments in hygienic processing.

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.
