Actuation

SIPOS Aktorik has reported a rapidly expanding network of global distributors. The company, which appointed five partners in 2010/11, has a total of 50 organisations supporting its variable speed actuators around the world.

Quarter-turn electric actuators boast rugged design ProMation Engineering’s P9-13 Series quarter-turn electric, non-spring return actuators feature a rugged, industrial grade design for use with all ball and butterfly valves or dampers requiring higher torque outputs from 17,500 in.

When fully open, Val-Matic’s EnerG AWWA rubber seated ball valve provides 100% clear flow are equal to the pipe size, and is the preferred selection for surge control, low headloss and energy savings.

Rather than using two 2-way automated valves to control the flow of liquids, a single 3-way valve does the job with fewer components and lower cost. Assured Automation’s PTP Series 3-Way Ball Valves can be used for flow diverting or controlling two flows coming into a single line.

Enertech, a business unit of Curtiss Wright flow control, has developed an extended mission gas spring actuator model to support nuclear plant cool down during station black conditions. Conventional electro-hydraulic, gas spring actuators are limited to one direction; fail safe positioning of isolation valves.

Emerson Process Management’s new Fisher® VBL booster incorporates a fixed deadband, internal soft seats and an integral bypass restriction that combine to eliminate the positioner problems typically caused by boosters without these design features.

The Valve Basics Seminar & Exhibition is a one-and-a-half-day program that has already drawn more than 400 people who need or want to learn about industrial valves, actuators and controls.

The EPZ series of industrial electric actuators was recently released by Hayward Flow Control. The EPZ Series is an economical solution for small diameter ball valves and well suited for tight-space applications.

Hayward Flow Control has introduced new EPM-4 and EPM-6 models to their EPM Series of quarter-turn reversing electric actuators. The EPM-4 and EPM-6 are designed to eliminate wiring errors, increase reliability, and provide simplicity during installation.

Assured Automation recently announced its 36 Series full port ball valve. It is a 3 piece ball valve constructed of 316 stainless steel and is available with threaded, socket weld and quick clamp ends.
