Valve Actuator is offered in universal and OEM versions.

2013-07-18 14:30:16| Industrial Newsroom - All News for Today

Universal Valve Actuator permits use of single motor and control software to operate any Valco or Cheminert rotary valve, both 2-position and multiposition. All Valco and Cheminert valves and selectors, with range of turning torques, are covered by 3 actuator versions: high speed, medium speed/medium torque, and high torque. Actuators include universal 24 Vdc power supply and manual interface, but OEM version excludes these items. Interface options include RS232/485, USB, and BCD.

Dispense Valve deposits flux for photovoltaic industry.

2013-07-17 14:31:24| Industrial Newsroom - All News for Today

Operating at speeds up to 500 Hz/sec, Square Wave™ 745NC deposits continuous lines of microdots on solder-coated metal ribbons that connect adjoining PV wafers. Solenoid technology minimizes process variation for repeatable dot-to-dot consistency, while low actuation speed of 2 ms prevents build-up of flux crystals on valve's nozzle which could prevent fluid from being deposited precisely on bus bar. With non-contact design, valve never touches delicate PV wafer, minimizing breakage and rejects. This story is related to the following:Green & CleanSearch for suppliers of: Solenoid Valves

Curb Control Valve Cavitation

2013-07-17 06:00:00| Chemical Processing

Cavitation is a damaging phenomenon that occurs within and downstream of control valves under certain well-understood temperature, pressure and media velocity conditions. At its very worst, cavitation creates high noise levels along with vibration, pitting and erosion of valves and piping.The noise may be annoying or severe enough to be...
