The UK’s leading independent provider of valve automation products, Actuated Solutions, has announced the exclusive availability of the KEH series quarter turn actuators from Quifer.

The KEH electro-hydraulic features a compact modular design, incorporating a spring return actuator and closed loop hydraulic pump. The springs provide a true failsafe action making the KEH ideal for critical and remote installations where instrument air is unavailable.

When energised, hydraulic pressure is generated to open the actuator, upon loss of power the KEH automatically moves to the failsafe position. The KEH springs do not require maintenance and are considered the industry standard for field proven reliable shutdown, offering better reliability than other solutions such as batteries which have a restricted temperature range, and require regular monitoring and periodic replacement.

ASL’s Director, Chris Hickey, said he was pleased to be adding the KEH series to the firm’s portfolio:

“The KEH is a real step forward in quarter turn actuation and it’s already proving to be very popular with customers demanding a robust solution for failsafe applications when air is not available. It’s a hugely versatile product and one that we know performs exceptionally well even in the most challenging of environments.”

The KEH series is available in nine sizes, delivering up to 1800NM of torque using a rack and pinion, and up to 50,000NM when using a Scotch Yoke. It offers multiple options – including push button local controls, limit switches, and manual override – and is available in a wide range of voltages from 24VDC to 400VAC Three phase.

SIL rated and available for both ATEX and safe areas, the new electro-hydraulic actuator affords users safety and functionality which includes full European certification and manufacture.
