Products

Thermoplastic Ball Valves
The new sizes of thermoplastic ball valves for 3-in. and 4-in. piping are available in polyvinyl chloride, chlorinated polyvinyl chloride, polyvinylidene fluoride, and polypropylene. Plast-O-Matic Valves (Cedar Grove, N.J.).

 

Low-Flow Measure
The Innova-Sonic® In-Line instrument measures clean liquids regardless of conductivity, with low-flow detection measured in picoseconds. It is designed to offer low power consumption and digital-signal processing with noise-filtering capacity. It has an accuracy of ±0.5% of reading and repeatability of ±0.07% of reading, a wide operating temperature range of –40°F to 176°F (–40°C to 80°C), and a bidirectional flow range of zero to 7 m/s (zero to 23 ft/s). Sierra Instruments Inc. (Monterey, Calif.).

Valves
The SCV Spring Check Valves are designed to prevent reversal of flow in piping systems and are suitable where backflow can damage pumps, filters, or process equipment. The valves are available in polyvinyl chloride with ethylene propylene diene M-class rubber O-rings or chlorinated polyvinyl chloride with fluorocarbon rubber O-rings, and in sizes 0.5 to 4 in. Dwyer Instruments Inc. (Michigan City, Ind.).

 

Mixers
The Series HGL (430-rpm) mixers are designed for easy integration with standard intermediate bulk containers or poly tote bins by use of an optional 2-in. type 316 stainless steel bulkhead fitting. The mixers feature a short shaft and a folding propeller constructed of type 316 stainless steel and designed to fit through a 2-in. opening with the propeller’s operating diameter of 9 in. A second folding propeller can be added as an accessory and bolted anywhere on the 0.75 in.-diameter shaft. Neptune Mixer Co. (Lansdale, Pa.).

Cavity Pump
The Moyno® 2000 progressing cavity pump for handling slurries and solids-laden materials is designed to provide torque and thrust control. Joint seals were designed to protect gear joints from contamination. The system is designed to offer flow rates to 2500 gal/min and pressure capabilities to 1000 psi. Moyno Inc. (Springfield, Ohio).

Infrared Thermometer
The Traceable® infrared thermometer measures both degrees Celsius and degrees Fahrenheit (between –55°C and 250°C [between –67°F and 482°F]) of the surfaces of solids, semisolids, and liquids. The unit, with wristband, was designed for simple operation and takes readings in less than a second with an accuracy of ±1°C +2% and a resolution of 0.1°. A laser beam was designed to provide target sighting. The unit measures 4 in. × 2 in. × 0.75 in. and weighs 2.25 oz. Control Co. (Friendswood, Texas).

 

Controllers
The new SCADAPack 330 and SCADAPack 334 controllers are the smallest in the SCADA series. Designed for power conservation, the controllers are programmed with TelePACE ladder logic, ISaGRAF (IEC61131-3) and C/C++, and support up to 32 independent C++ applications. The controllers use Modbus and DNP3 serial protocols, as well as Modbus TCP and UDP-based ethernet protocols. Control Microsystems (Kanata, Ontario).
