Equilibar, LLC.
Back Pressure Regulator for Low Pressures The Equilibar SC uses a patented multi orifice design to control back pressures at very low pressures. The SC is a pilot operated back pressure regulator. Pilot pressure is applied to one side of a diaphragm and system pressure to the other side. Any system pressure above the pilot set point is smoothly and proportionally vented out of the system. By carefully selecting diaphragm materials to match the pressure, temperature, and chemistry requirements of each... (read more)Browse Industrial Valves Datasheets for Equilibar, LLC. -

F.B. Leopold, a Xylem brand
Reliable Protection from Seawater Contaminants Leopold ® desalination pretreatment systems can significantly reduce membrane-fouling contaminants —color, organics, soluble metals, oil, algae —before they reach your reverse osmosis (RO) membranes. These seawater contaminants can affect effluent quality, damage the membranes, and even cause membrane failure because RO membrane filters are intended for removing only salt and dissolved ions when producing potable water from seawater. Solutions for Every Desalination Pretreatment... (read more)Browse Desalination Equipment Datasheets for F.B. Leopold, a Xylem brand -

Leister USA
Operate Your Instrument at Lower Pressures One group of analytical instruments samples ambient air using a simple pump and would prefer not to deal with the size, weight and cost of a stronger pump. For these instruments, pressure drop across the flow control element is very important. For other instruments, the pressure drop contributes to a decrease in measurement performance. The Axetris line of thermal mass flow products were designed for minimum pressure drop. The MFC2022 mass flow controllers need as little as 0.7...
