Trouble-free service

With parts made from wetted aluminum for corrosion protection, the Series 2119V diaphragm pumps work in class B steam autoclaves. The pumps, which provide up to 27 inches Hg vacuum and have a maximum flow rate of 0.81 CFM, offer resistance to steam and water because their umbrella valves and diaphragms are constructed of EPDM. Also, the pumps provide durability from their engineered resin and die-cast aluminum construction. Rietschle Thomashttp://rbi.ims.ca/3855-594


No circuitry or wiring changes

The company's "FlexSAM" system provides up to 32 inputs and 32 outputs without the wiring of remote operating valve manifolds. The modules utilize DIP switches for node addressing and baud rate setting, eliminating the need for software and reportedly reducing trouble-shooting time. Due to featured NEMA 4 protection, the modules can be mounted directly on a machine with no need for an enclosure. The company offers Input and Output Module Kits, and Connector Module Kits for single and dual Sub-D 25-pin, circular 19-pin, or M23 connectors. Parker Hannifinhttp://rbi.ims.ca/3855-595


Meets rigid requirements

Designed to the 3-A Sanitary Standards for Clean-In-Place and Sterilize-In-Place environments, the Hedland FlowClean turbine flow meter meets the requirements for monitoring flow in food, beverage, and pharmaceutical applications. This flow meter reportedly features a Turndown Ratio of 10:1, accuracy reading of plus or minus 1 percent, and repeatability of plus or minus 1 percent. The meter is available with sanitary clamp-end connections in sizes from 19 to 63 mm, with an operating pressure of 1,000 psi, and temperature ratings from -100 to +300F.

Three bore sizes available

Designed to prevent monetary losses due to contamination in the production process, this rodless cylinder offers the only IPA-certified design for cleanroom specification avaliable on today's market. It is available in three sizes: 16, 25, and 32mm. Hoerbiger-Origahttp://rbi.ims.ca/3855-597


Six available pressures

This pump combines the power of 350 or 425 hp with the flexibility of changing pressures. Designed for long life and fast conversions, the pump features a slow-running triplex plunger pump, hard-coated valves and plungers, and corrosion-resistant stainless steel. A polychain system and water pressure-actuated throttle control adjust output to operator demand. Because it requires fewer parts to change pressures than other convertible pumps, the product reportedly reduces cost and downtime. The basic kit offers six pressures: 8,000, 10,000, 13,000, 15,000, 17,000, or 20,000 psi. NLB Corp.http://rbi.ims.ca/3855-598


Versatile in customization

Created as a general utility pump, this product can handle clean, clear liquids as well as viscous, harsh, and corrosive fluids. Suitable for water sampling, as well as pumping adhesives, paints, and coatings, chemical slurries, ink and oil scum, the pump's versatility enables customization for any specific plant. The progressing cavity pumps have a lightweight design, feature self-priming, and are said to require little maintenance. They accommodate flow rates to 50 GPM, pressures to 600 psi, and fluid temperatures to 240F. Moyno Inc.http://rbi.ims.ca/3855-599


Air pressure tested

Created with full port construction for application in water, oil, and gas transmission and handling, these valves feature stainless steel balls for precise operation, Teflon seats and seals, and a locking safety handle. The valves undergo air pressure testing under water, and are rated up to 1,000 psi. The 316 SS models are available in sizes ranging from 0.375 to 3 inches. Bee Valve Inc.http://rbi.ims.ca/3855-600


Replace multiple valve installations

The double block-and-bleed valves' design reportedly allows for an easy transition from process to instrumental systems in one compact valve assembly. Each piece contains a primary isolation valve with a variety of secondary block-and-bleed valves. The valves' benefits over traditional systems may include fewer leak points and reduced mass. They are available in sizes ranging from 0.5 to 2 inches, and rated to temperatures from -50 to 400F, with pressure ratings in the 150- to 2,500-lb class. Swagelokhttp://rbi.ims.ca/3855-601


Vacuum version available

The Type 316 stainless steel pressure gauge is available in many single-scale pressure ranges: 0-30 psig, 0-60 psig, 0-160 psig, and 0-200 psig. The instrument, designed to withstand vibration, pulsation, and mechanical shock, is also available in a vacuum version for 30-0 Hg, and a compound scale model is available for the pressure range of 30 Hg-60 psig. The gauge is suitable for many applications including chemical process, petrochemical, pharmaceutical, food, beverage, pulp, and paper manufacturing. Spirax Sarco Inc.http://rbi.ims.ca/3855-602


Can be used in food industry

This two-way, normally opened solenoid valve for a drain can withstand media temperature of 220F and ambient temperature of 140F. The valve has a life expectancy of up to 300,000 continuous cycles with opening and closing response times of 1 to 2 sec. Available in ac voltages with a flow rate of 4.5, the new drain valve holds CSA and CE approvals and the enclosure meets NEMA 4 standards. Parker Hannifinhttp://rbi.ims.ca/3855-603


Designed to extract fumes

Three new models of the FilterCart have been added to the Nederman line, all of which have a 7-ft extraction arm. The FilterCart Standard model features 270 ft2 of filtration surface area and general purpose extraction hood. The FilterCart Original model offers a 376 ft2 particle filter as well as a built-in halogen spotlight. The FilterCart Carbon model has 300 cfm air handling through 44 lbs of activated carbon. All systems are low maintenance and portable. Nederman Inc.http://rbi.ims.ca/3855-604


5000-hour life expectancy

Designed with more features than their predecessor, the L-PAK 150 and L-PAK 250 can extract welding fumes, metal chips, and sanding dust from workstations and machines. Both units have a standard filter system that separate heavy particles and have a HEPA filter option that can remove up to 99.997 percent of all particles in the air. Both models are quiet, running 63 dB with a sound insulation hood and both models were designed to compliment the E-PAK series, taking features from the E-PAK including the automatic filter cleaning, thermal overload protection, and motor protection. New features for the L-PAK include an automatic start/stop feature and a propylene filter. Nederman Inc.http://rbi.ims.ca/3855-605


Single-stage, direct acting

Designed to provide a flow rate linearly proportional to the input current, this valve has a flow capacity that reaches a Cv of 0.2 over a pressure range of 25 to 70 psi with air flow rates of 120 slpm at 25 psig inlet. Available in 5, 12, or 24V dc versions, the valve has the option of hard seats to eliminate friction and make the valve highly repeatable with low hysteresis or soft seats for bubble-tight sealing.

For pressure, velocity, and flow applications

The Series DH DigiHelic(R) Differential Pressure Controller from Dwyer Instruments is useful with many different pressure, velocity, and flow applications. Users can choose what security level they want, alarm operation standards, measurement units, duct size, and K-factor adjustment for Pitot tubes and flow sensors. The controller can operate from either 120/220V ac or 24V dc, as well as provide a 4-20 mA process output, two SPDT relays with adjustable dead bands, and a 0.5 percent full scale accuracy on ranges from 5 inches w.c. to 100 inches w.c.

Useful with elevated temperatures

Built with a diaphragm seal to provide a leak-free product even in a non-flowing condition, the Corzan Series CKM Check Valves resist corrosion and work well in elevated temperatures. The diaphragm valves used are not dependent on gravity, mounting position, or reverse flow to function properly. The valves are available with 0.5-, 0.75-, and 1-inch pipeline connections. The valves, made of Corzan(R) CPVC, can prevent potentially dangerous reverse flow in piping systems Plast-O-Matic Valves Inc.http://rbi.ims.ca/3855-608
