Explosionproof CMA actuators deliver "Performance Plus" process valve control
17 April 2014, Bath (United Kingdom)

Available in quarter-turn, rotary and linear versions, robust Rotork CMA actuators perform numerous process control valve, metering pump and damper applications. Single-phase or DC electrical power is all that is required for simplified installation and control valve actuation in safe or hazardous areas. Explosionproof certification to international standards is available.

The latest "Performance Plus" development introduces a user selectable increased shut-off torque/thrust option. Developed in response to industry feedback, this option enables a more tailored and cost-effective sizing regime to be applied to both the modulating and tight shut-off demands of the control valve. A tight shut-off is often required as part of the valve duty, leading to potential over-sizing of the actuator for mid-travel modulating operations. The increased torque/thrust option is selected and configured during the actuator set-up programme, as part of a logical menu-driven process using an internal electronic LCD display and pushbuttons.

Voith Hydro Presents New Study on the Role of Pumped Storage Systems in the Energy Transition in Berlin: No More Waste o
15 April 2014, (Germany)

Utilizing wind and solar energy more efficiently, cutting down on fossil fuels and providing secured capacity - this is the contribution to be made by pumped storage power plants in Germany by 2050. This is the key result of a new study of Rheinisch-Westfaelische Technische Hochschule Aachen (RWTH Aachen University) about the future role of pumped storage power plants in Germany. The study, commissioned by Voith Hydro, was presented in Berlin today.

Within the context of the energy transition, the scientists of RWTH examined the role of pumped storage power plants, i. e. large power stores, for two scenarios: one for the year 2030 with a 60 percent share of renewable energies in power generation, and one for the year 2050 with a share of 80 percent...(+)

Emerson releases new bulk storage tank relief valve for propane tank applications
11 April 2014, Mckinney (TX) (United States)

Emerson Process Management has released the new Fisher Type 63EGLP Bulk Storage Tank Relief Valve, typically used on 30,000 gallon and larger propane tank applications. The Type 63EGLP offers multiple benefits over traditional multiport relief valves, including a 40% increase in relief capacity, a 20% weight reduction for easier installation, and reduced maintenance costs. The UL-certified relief valve is approved for bulk propane storage relief installations compliant with NFPA 58.

The Type 63EGLP achieves significantly greater relief capacity than a traditional multiport relief by incorporating a highly accurate pilot controlling valve. This pilot controlling valve has been used for decades in petrochemical and natural gas applications and has proven to be both accurate and highly reliable. The 40% capacity increase translates into significant savings for tanks of 90,000 gallons or larger, requiring only two Fisher Type 63EGLP's versus three traditional multiport relief valves. Installation is simplified due to a 20% reduction in weight and a reduction in overall size in comparison to multiport relief valves, along with an included lifting sling.
