  Versatile AC drive

Allen-Bradley PowerFlex 750 Series AC drives from Rockwell Automation are designed for ease of use, simplified integration and application flexibility. With a power range of 0.75 to 1,500 kW and 400/480 and 600/690 volt capability, the drives offer predictive diagnostics and built-in protection. They have a slot-based hardware architecture that reduces unnecessary add-ons and lets users select option cards to suit an application and expand the drive for future needs. 414/382-2000; www.rockwellenergycalc.com.

  Adjustable-speed drive

The P9 low-voltage adjustable-speed drive from Toshiba International Corp. uses Virtual Linear Pump (VLP) Technology, which creates a linear system curve by automatically tuning the drive to a system and assigning maximum and minimum operating points. Using transducer feedback, the process control mode maintains a setpoint with minimal rise time and virtually no overshoot, settling time or steady-state error. This mode can be used to maintain pressure, flow, level or temperature. Benefits include running the device at its best efficiency point, load sharing over multiple devices, sleep-timer control and the ability to turn on secondary devices. It is best suited for pump and blower applications. 800/231-1412; www.toshiba.com/ind.

Seals

  Bearing protection ring

The AEGIS SGR bearing protection ring from Electro Static Technology supports predictive and preventive maintenance programs on AC motors and large DC motors controlled by variable-frequency drives. By protecting bearings from electrical damage, the ring extends motor life, preventing bearing noise, downtime and motor repairs/replacements. It simplifies predictive/preventive maintenance programs. Its conductive microfibers work with virtually no friction or wear; are unaffected by dirt, grease or other contaminants; and last for the life of the motor. A mounting kit simplifies installation on any NEMA or IEC motor. It prevents bearing damage by safely channeling shaft currents to ground. 866/738-1857; www.est-aegis.com.

Valves

  Two-way diaphragm valve

The Type 2030 from Burkert Fluid Control Systems is a pilot-controlled diaphragm valve with piston actuator and diaphragm seal. The two-way diaphragm valve with a PVC or PVDF body provides high flow rates and chemical compatibility. The diaphragm and valve body are the only components in contact with the fluid. It can be combined with any Burkert pilot valves, on/off top control or element controllers, valve blocks, manually operated valves or solenoid valves. It includes a removable radial true union, spigot and flange connections. 800/325-1405; www.burkert-usa.com.

  All-plastic control valve

The Model 2060 2-inch flanged plastic control valve from Collins Instrument Company has a body of PVDF or polypropylene and an actuator/yoke of glass-filled polypropylene, making it suitable for harsh fluids or corrosive environments. It can be equipped with a pneumatic positioner, a positioner with integral I/P or an electric actuator. It has 150 psi flat-faced ANSI flanges, accommodates 300 psi maximum operating pressure at ambient temperature, and handles fluids including hydrochloric acid, caustic, sulfuric acid and others. 979/849-8266; www.collinsinst.com.

  Non-clogging air valves

The AirPro Max air valve line from Henry Pratt Company resists clogging. The float/linkage design is suitable for higher pressures. It eliminates seat leakage and float mechanism failures and includes close-tolerance machined parts, stainless trim, and hoods or threaded caps. Valves have a large orifice to break vacuum or a small orifice for air release under pressure. 877/436-7977; www.henrypratt.com.

  Electric modulating actuator

CMA Series electric modulating actuators from Rotork Instruments are sized for linear, quarter-turn, and rotary operation of pump, damper, and control valve applications requiring precise position control and continuous modulation. They are powered by single-phase or direct current, eliminating air hoses and compressors. Setup and configuration is easy via pushbuttons and an internal six-segment LCD display. Resolution is 0.20 percent on linear and quarter-turn applications and 2 degrees on the multi-turn configuration. Other features include a permanently lubricated and maintenance-free drive train, a 4-20 mA loop-powered feedback signal and multiple digital communication options. 336/659-3493; www.rotork.com.

  Pressure-reducing valve

The SRD Pressure Reducing Valve from Singer Valve provides smooth, steady and precise pressure control from maximum to near-zero flow without low-flow bypass valves. The effective area of a single rolling diaphragm remains constant, so the bonnet is smaller and lighter than a flat diaphragm version. A measured quantity into the bonnet control chamber gives the same smooth movement of the inner valve through the stroke. A smaller bonnet also makes the valve lighter and safer for maintenance, while a smaller control chamber enables it to respond faster to changing pressures. Sizes range from 6 to 36 inches. 604/594-5404; www.singervalve.com.
