PUMP SERIES PROVEN FOR PETROCHEMICAL PROCESSES Pulsafeeder Engineered Products PulsaPro & Pulsa series petrochemical pumps are available from John Brooks Company. For high pressure injection of hydrocarbons, catalysts, peroxide, hexane or where process chemicals are flammable and atmospheres are hazardous, a PulsaPro hydraulically actuated diaphragm a metering pumps are said to provide v dependability and safety. Full motion stroke s length control yields 0 to 100% linear e flow adjustment over a 10:1 turndown range r at ±0.5% accuracy from set point. Pulsa P versions include a proven hydraulic management m system said to assure consistent t performance and rapid recovery from system s upsets.

R. STAHL has expanded its range of intrinsically safe ISpac isolators portfolio. The isolators are 17.6 mm wide and are available as a single- and dual-channel in typical applications, ranging from analog inputs, analog output, discrete input, solenoid driver, RTD, and TC, as well as ssome specialized applications like frequency converter, seriaal communication, and vibration transducers. The isolators aare globally certified (NEC, CEC, ATEX, IECE, EAC, DNV, PESO, K KCS) for installation in Zone 2, and Class I, Div. 2 with I.S. sign nal to Zone 0, and Class I, II Div 1. ISpac modules from series 9 91XX and 92XX fulfill the functional safety criteria according to SIL 2 or SIL 3. All modules can be mounted directly on the DIN rail and, snapped onto a pac-Bus, combine across aall models to make them future-proof, the company says.

Plast-O-Matic has introduced CAFE actuators that provide automatic voltage sensing from 24 to 240 Vac/Vdc, with standard manual override, position indicator, LED status lights, overtorque protection, condensation heater and thermal protection. Standard actuation time is 5 s with 15 Nm torque. The CAFE NITRO model includes programmable options via OLED screen, complete menus, fully directional keypad, and onboard diagnostics. Variable speed can be set from 4 to 6 s via the OLED screen. Both models include mounting kit, multi-mode electronic over-torque protection against valve jam, brushless motor with ICP protection, thermostatic anti-condensation heater, remote position indicator via programmable relays, and barrel style visual position indicator. Units also include weatherproof anti-corrosive and UV protected, and are CE marked with IP67 ingress protection. The actuators are designed for 2-way valves, the company says, with 3-way valves available with a factory consultation. ne
Bonomi North America has announced CSA approval on the company’s Valbia electric actuators, models VB030M and above. This approval is important in Canada where it is required for installation, the company says. Valbia electric actuators are built with water-tight cast aluminum or techno-polymer enclosures that can be used indoors or outdoors, the company adds. The electric actuators feature steel and techno-polymer gears with hardened steel pinions said to provide long life and quiet operation. Benefits include two extra limit switches, a heater and thermostat, and a 75% duty cycle motor. All models are dual voltage. A manual override is also standard.
