AUMA: Explosion-Proof Variable Speed Actuators

AUMA explosion proof variable speed actuatorsAUMA has launched explosion-proof variable speed valve actuators for use in potentially hazardous environment. The new SAVEx actuators for open-close duty and SARVEx multi-turn actuators for modulating duty, combined with intelligent ACVEx actuator controls, provide full control of the motor speed at any time.

In oil and gas applications, variable speed offers significant advantages for challenging valve control tasks, since it allows the optimum operating speed to be selected for each change of valve position. High positioning accuracy and optimized setpoint control considerably increase the effectiveness of pressure control valves in gas pipelines, for example. On multiport valves, variable speed actuators aid rapid and accurate switch-over between ports.

Mechanical stresses on valve, actuator and pipeline are minimized by reducing the operating speed close to the end positions, allowing the moving element of the valve to make gentle contact with the seat. Pressure surges and cavitation effects in the pipeline can be avoided by using speed profiles.

Hunt Valve: Interactive Actuator Configurator

hunt valve launch interactive actuator configurator built by cadenas partsolutionsHunt Valve has launched an all-new interactive actuator configurator built by CADENAS PARTsolutions on the eCATALOGsolutions platform. The new online tool features Hunt's rod-style and rodless actuators, enabling users to instantly configure, download and virtually test within their design environment. By providing on-demand access for customers to get digital product information, Hunt is boosting their online digital customer experience and becoming even easier to buy from.

The process to customize actuators, which formerly took 24-48 hours, can now be done in seconds. Engineers and designers simply navigate to the actuator they need on www.huntvalveactuators.com and configure the product to fit their needs. They get an instant 3D preview of their configuration to ensure accuracy before downloading a 3D CAD model in their choice of 100+ native and neutral formats. The downloaded 3D CAD model can then be tested in a live engineering environment to ensure proper fit and function.

Velan: New Patent-Protected Cable Drive Actuator

Velan ABV ALTO actuatorPresented at Valve World Conference & Expo 2016 in Düsseldorf, Velan ABV’s new patent-protected cable drive actuator benefits from a transmission system with constant torque and high accuracy along the entire quarter-turn rotation. Its modular construction comprises a center body, pneumatic or hydraulic power cylinder and a spring cartridge for emergency action. It is the actuator’s newly designed center body with its revolutionary cable drive system that separates it from the standard scotch yoke actuator.

“We’ve had considerable experience over the years designing and manufacturing extremely high-quality valves and actuators. This new design builds on that expertise and takes it to the next level,” said Paolo Ranieri, CEO of Velan ABV. “First off, the features of our new actuator help cut operational costs. Since it produces 30% more running torque than traditional scotch yoke actuators, smaller actuators can be installed. Fewer components and less friction mean lower maintenance--and it’s safer to run.”

Yves Leduc, President of Velan, added: “Velan is introducing a unique and innovative quarter-turn actuator that offers strong benefits for control precision in a cost-effective package. Our decision to expand our portfolio of actuators is in line with our strategy to leverage our innovation capabilities in addressing specific end-user needs that remain underserved.”  

AUMA: Multi-Turn Actuator for Underwater Use

AUMA Actuator for Underwater UseThe AUMA SA multi-turn actuator for continuous underwater use opens new applications for electric actuators: for water supply, in hydropower plants, in civil engineering constructions for water applications, and for specific underwater applications. Where both water supply and sewer pipes are underground, actuators and valves are often installed in pits below ground level. Where high water levels are a permanent risk, actuators designed for underwater use will operate reliably even if flooding persists.

A universal sealing system combined with comprehensive corrosion protection qualifies these actuators for underwater use. Double-sealed cable glands at the electrical connection, inner seals – some in pairs – on all housing covers, and a one-piece solid shaft prevent the ingress of water.
