Actuation

LaunchPoint Technologies (LaunchPoint) recently completed testing a new version of its variable valve timing (VVT) electromechanical valve actuator (EVA) for internal combustion engines. The new design reduces power consumption by more than 50% compared to the previous design and has, thus far, exceeded 1 million cycles of endurance testing.

DTL have launched a standard range of butterfly dampers that provide a simple and cost effective method of control and isolation for many industrial applications requiring a shut-off of up to 99%. The new range, which is powered by Rotork actuators, will be supplied in diameters ranging from 200mm to 1200mm (in increments of 50mm).

F.lli Scapin’s brand-new RPM ‘Portable valve gearbox’ for valves operators helps easy and fast opening/closing on underground water valves not equipped with a reduction gearbox and usually moved by a Tee Key, valve requiring high Nm values (rather than manual work of one single operator) or valves needing a high number of turns to be fully open or closed.

Operating valves in water and waste water installations can be a laborious and dangerous task, especially if the valves are used infrequently, corroded or have varying torque requirements.

K Controls submersible valve position monitors can be fitted to a wide range of 1/4 turn or linear hydraulic sub-sea valve actuators. They continuously monitor the valve position through 4–20mA + HART, PROFIBUS PA or FOUNDATION FIELDBUS signals.

Building on the success of its low-cost SV range of single-flanged slide gate valves, Mucon developed an in-line version for applications requiring a flange connection at the outlet, the Mucon DSV Slide Gate Valve.

Val-Matic’s Ener•G Rubber Seated Ball Valve is a preferred solution for surge control and energy savings in municipal and industrial water and wastewater. The Ener•G Ball Valve’s self-flushing contoured ball design fully complies with AWWA C507.

Westlock Controls announced a new addition to its ICoT smart valve positioner 6000 series. Designed with strong aluminium and stainless steel enclosures and certified as explosion-proof to global standards, the positioners suit both spring-return and double-acting actuators for rotary and linear valves.

Bonomi North America is launching its new line of low-torque ANSI Class 150 flanged industrial full-port ball valves, designed for direct mounting of any reasonably sized ISO standard actuator.

A V-Flow customer needed to control and monitor the flow of seawater from a remote location. There were very specific details of how the valve should integrate with existing pipework.
