Intended for high-viscosity, nonabrasive fluid applications, the HPD Series of positive displacement flowmeters and batch controllers reportedly offer seamless integration into any central process control system. According to the company, they maintain a consistent accuracy within plus or minus 0.5 percent at low flow rates, despite changing viscosity conditions. Applications include oils, greases, polyurethanes, solvents, chemicals, additives, lubricants, and fuels. Hedland Flow Metershttp://rbi.ims.ca/3860-636


Multiple configurations

Available with up to 16 positions in five configurations ranging from simple stream selection to more complicated trapping functions, the MW Type Multiposition Valves from Valco offer a wide variety of flow configurations, port and fitting sizes, and actuation options. Traditionally made of stainless steel, the valve body can also be ordered in materials such as Hastelloy C-22 or Nitronic 50. The valves' preload design allows the rotor to be inspected or replaced without removing the valve from the actuator. Valco Instrumentshttp://rbi.ims.ca/3860-637



The Trap-Seal(TM) from Parker Hannifin Corp. provides improved seal reliability by reducing the possibility of the O-ring popping out of the O-ring face seal (ORFS) groove. Featuring greater seal retention, reduced risk of seal damage and leakage, and a smoother pre-assembly process, the Trap-Seal is designed to stay securely lodged under the ORFS groove lip. The Trap-Seal is also interchangeable with the standard O-ring used in half-dovetail grooves, making seal replacement quick and easy. Parker Hannifinhttp://rbi.ims.ca/3860-638


Clean airflow

The Series 2770 WOB-L(R) Piston pumps reportedly provide long life, clean airflow, and field serviceability, making them suitable for a range of medical, dental, HVAC, and other OEM applications. They are designed with light yet rugged die-cast aluminum, the company says, and use stainless steel valves with a patented recessed inlet valve. The cylinder is reportedly hard-coated for wear resistance, with all wetted aluminum parts treated for corrosion protection. They provide up to 100 psi of pressure, with maximum flow rated at 7.4 cfm, according to the company. Rietschle Thomashttp://rbi.ims.ca/3860-639



The DR20 is designed as a compact, light-weight valve for use with any small to moderate steam requirement. According to the company, superior flow characteristics through the use of a flow-up design, as well as a flat valve and plug arrangement, promotes secondary pressure stability. The stability reportedly augments the pressure reduction capability to allow the product to reach a turnover ratio of 30:1. It has a stainless steel construction.

Improves system performance

Designed for all vacuum system applications requiring the prevention of vacuum loss, the CheckVac valves are a line of reportedly leak-proof, one-way vacuum check valves. They are constructed from a one-piece, seamless aluminum body and plastic valve element that snaps into place and has an O-ring seal. They feature low cracking pressure and a smooth bore, providing up to a 4x better flow rate than typical check valves made for compressed air systems, according to the company. This increased flow rate reportedly enables the use of smaller vacuum pumps. Anver Corp.http://rbi.ims.ca/3860-645


MAMUR compliant

The company's accessories for their line of pneumatic actuators include three- and four-way solenoid valves, pneumatic positioners, electro-pneumatic positioners, valve status monitor, and proximity position indicator.

Available in two sizes

The RFIK is a hydraulic tester that features reverse flow capability up to 50 gpm and working pressure to 6,000 psi, according to the company. It is designed for safe in-line testing of mobile or industrial hydraulic circuits where reverse flow conditions may occur. The reverse flow feature is designed to permit quick and easy circuit checks by allowing the machine to be fully cycled during troubleshooting; it reportedly prevents cylinder lock-up and possible pressure intensification. It is available in two sizes: 32 and 50 gpm. Webster Instrumentshttp://rbi.ims.ca/3860-647


Fast response time

The J-Series inline exhaust valve reportedly provides fast response time and high flow rates with its 1/2- and /-inch ports. The all-brass construction and 100 percent testing assures the highest level of quality, according to the company. It is designed to increase cylinder speed, as well as allow the use of smaller directional valves and longer control lines. It can also be used as a shuttle valve.

Pneumatically operated

The ADP-1 pneumatically operated liquid drainer does not waste air and has a see-through reservoir. The ADP-1 has a press-to-test actuator and is good for draining oil/water separators. Easy to mount on base-mounted compressors, remote cooler packs, refrigerated air dryers, and filters because of its low profile, the ADP-1's other features include a press-to-test actuator, vent valve, a non-clogging ball valve, and the absence of strainers to clean. There is also the option of legs, a heater, and a mechanical cycle counter. Armstrong Internationalhttp://rbi.ims.ca/3860-654


For caustic solutions

Engineered for a range of caustic applications, the company's M900 diaphragm pumps are engineered with automatic volumetric venting valves that safely discharge any vapor or gas bubbles forming in the hydraulic reservoir caused by caustic solution reactions. They feature seal-less ptfe sandwich diaphragms that reportedly don't need a front support plate and can easily handle abrasive slurries. In addition, they offer plus or minus 0.5 percent steady state accuracy, repeatability, and linearity, according to the company. American Lewa Inc.http://rbi.ims.ca/3860-655


Microprocessor controlled

The Smart flowmeters from J-TEC Associates Inc. were designed for all gas and steam applications. The devices compensate for any material's pressure, temperature, and viscosity that they are handling by being microprocessor-controlled. Other features include a flow range as low as 0.4 scfm, wafer and insertion styles, built-in temperature sensors, 70 to 1 dynamic range, drift-free performance, minimal pressure drop, and no moving parts, making the flowmeters maintenance-free. The flowmeters are also calibrated to NIST traceable standards. J-TEC Associates Inc.http://rbi.ims.ca/3860-656


No need for overhead lifting devices

Featuring a 24 filter bag model that handles flow rates of up to 4,500 gpm, the MAXLINE(TM) MBF HD multi-bag filter housing is a bag filter that is available in either carbon steel or stainless steel. The MAXLINE MBF HD has incorporated a handwheel-operated davit cover into its design to combat the problem of replacing filter bags, which was a problem prior to this because of the heavy cover present on many models' bag filters. Designed to accept the many different size 02 filter bags available from Hayward, the filter will also work with standard 7- x 32-inch bags. Hayward Industrial Products Inc.http://rbi.ims.ca/3860-657
