FIRE SUPPRESSION SYSTEM ADDS PROTECTION FLUID
ELECTRICALLY-ACTUATED PRECISION SPRAY NOZZLES
Fike
John Brooks Company
Fike has announced it will now offer 3M Novec 1230 fire protection fluid in its patented Impulse Valve Technology fire suppression system. The company’s fire suppression systems are manufactured with impulse valve technology to improve the release of the agent into the zone with greater precision and reliability. The patented valve uses the Fike AXIUS rupture disc, enabling systems with smaller diameter pipe, longer flow distances and greater design flexibility than most other systems, the company says. The fire protection fluid is waterless, discharged as a gas, leaves no residue, and is electrically non-conductive, making it suitable for quickly extinguishing fires in spaces occupied by electronics or irreplaceable assets and where business continuity is critical. Its environmental profile supports sustainability and LEED initiatives with zero ozone depleting potential and a global warming potential that’s less than one.

L..J.. Star has introduced a design concept to visual flow indicator assemblies. Designed for hygienic/sterile applications in pharmaceutical, food/beverage, brewery and biotech industries, the clamp type sterile visual flow indicator, or CT-SVFI, uses a patent-pending design to prevent the O-ring seal gaskets compression issues that lead to contamination associated with conventional screwed or threaded fittings. The unit uses a mechanical stop design rather than screw threads said to apply precisely controlled compression to O-rings and provides up to 34 percent greater view area. Units maintain an EN10204 3.1 certification, along with FDA and USP Class VI certified O-rings and is fully compliant with the requirements of the European Pressure Equipment Directive 97/23/ EC. The product uses SF4 (15Ra EP) 316L stainless steel, with full material traceability. EPDM is the standard O-ring material, with silicone and other options available in tube OD sizes from ½ to 4 in. The glass material is made from borosilicate. od

The DCAP-PV pump from Ralston Instruments is said to generate pressure and vacuum easily and then control pressure to very precise test points. If the transmitter is an absolute pressure transmitter, the hand pump can generate a vacuum to reach below ambient pressure test points. The Ralston Quick-test system of hoses and connectors also lets the user connect without thread tape to each adapter and in many cases also to the device being calibrated without a wrench. For setting pressure switches, a pump with good control of pressure or vacuum is required. The fine adjust piston on the hand is said to very precise and lets the user open or close a pressure switch easily. In addition, the hand pump works well for calibrating flow computers which require precise control of pressure to each side of the differential pressure cell, the company says.

BETE electrically-actuated hydropulse spray nozzles from John Brooks Company are available for hygienic (EHP) and industrial (EHPI) applications. Units are said to assure precision volumes are sprayed directly onto your processing target, with overspray waste virtually eliminated. The automated nozzles don’t require a compressed air source and are capable of cycling on/off up to 150 cycles per second. These features afford the option of using high-frequency cycling known as pulse width modulation (PWM) to vary the liquid spray flow rate at constant supply pressure with little change in spray performance by adjusting the duty cycle. When the spray cycles at a high enough frequency, coverage uniformity is maintained because the duration between pulses of spray is short enough to ensure there are no gaps in the spray coverage, the company says.
