Aseptic Control Valves For High-Purity Processes

Samson Controls offers a range of valves that are self-draining and incorporate cavity-free internals to help promote effective CIP and SIP for food processing and pharmaceutical applications. The valves are manufactured to quality assurance systems certified to ISO 9001 and meet stringent FDA requirements for aseptic process applications. For example, the type 3347 control valve has polished steel parts to ensure high purity for the process medium by eliminating areas that may increase the potential for bacteria growth, such as traps and crevices.

They also feature a special PTFE bushing and an additional steam line connection that is used to meet the high-purity requirements and prevent bacteria from spreading at the actuator stem guide. Another example is the type 3249 valve, which is equipped with an EPDM diaphragm and a back-up safety packing box to ensure total protection against bacteria spreading and prevent product leakage. These sealing systems, which constitute the main components of the valve construction, have been designed to ensure a long and reliable service life.

Finally, process applications that involve pasty, fibrous or highly viscous products can be controlled by Samson's type 3345 cavity-free valve body, which features a diaphragm made of either rubber, nitrile, butyl or PTFE that acts both as a seal and a valve plug. These valves can be easily installed into the process line as they are available with various connections including hygienic couplings, flanges and clamp connections according to ISO 2852 and welding ends.

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.
