Rotork works with New York City Fire Department to keep the city safe

Published

on

The fireboats used by the Marine Division of the New York City Fire Department (FDNY) use Rotork ’s IQ range of part-turn intelligent electric actuators to keep the city safe.

The IQ part-turn actuators provided are used on two fireboats, ‘Firefighter 2’ and ‘Firefighter 343’. The actuators have the important duty of controlling the flow of water to the fire nozzles on deck, meaning that they are vital in the event of an emergency.

New York City is one of the busiest ports in the world and has 560 miles of waterfront. The FDNY has long employed the use of fireboats in order to combat fire-related incidents both on land and on the water. These 2 ships are the largest ones in their fleet.

Water is extracted from the river upon which the fireboats operate and the actuators then control the flow from the river to the fire nozzle. This ensures that the fireboats have access to an endless supply of water in the event of an emergency. It is critical that the flow of water to the fire nozzles is maintained at all times. Additionally, the fire nozzles are sometimes used to spray water at festival displays such as Memorial Day, the 4th of July, and Fleet Week.

The IQ actuators were installed as a retrofit, after the existing electric actuators installed previously failed due to water ingress. The Rotork actuators were chosen for their longevity and reliability. With water ingress protection, they are double sealed to IP66/68 (20 m for 10 days).

The IQT actuators are capable of up to 1,200 starts per hour, making them ideal for a fire-fighting application where duty cycles can be very demanding in emergencies.

As cunning as a fox: AUMA’s new smart actuators

Published

on

What do a fox and an electric valve actuator have in common? A lot, if the actuator in question is AUMA’s brand-new PROFOX. Like its namesake, PROFOX is not only cunning and adaptable but also extremely hardy.

AUMA’s more than 50 years of experience developing and manufacturing electric actuators has yielded a high-performance actuator series with exciting new features and an excellent cost-benefit ratio. Aimed at applications requiring fast and precise positioning, utmost flexibility and future-proof interfaces, the smart and compact PROFOX series is suitable for all industry sectors, including water treatment, combined heat and power plants, process industries, and shipbuilding.

Cunning

Built-in intelligence makes PROFOX equally suited to both simple open-close duty and challenging modulating applications. Motor speed is adjustable, ensuring fast and precise positioning without overrun. Soft start and soft stop functionality increases valve lifetime. Operating costs are low, thanks to high mechanical efficiency and low standby consumption. Innovative diagnostics ensure long-term availability and future-proof PROFOX actuators for IIoT applications.

Adaptable

AUMA PROFOX actuators work with gate, butterfly, ball and globe valves. There are multi-turn versions for torques of 10 – 100 Nm and part-turn versions delivering 32 – 600 Nm. A linear actuator will follow soon. Modular design ensures flexible configuration, rapid delivery and consistent operation. Host system integration is equally flexible; PROFOX actuators support the most common communication protocols and are well prepared for future evolutions. Compact design allows PROFOX actuators to fit tight spaces.

Hardy

The PROFOX series is engineered and built in Germany – and designed to last, even under the toughest process conditions. High-quality metal housing with IP67 protection (IP68 optional) and AUMA’s unique corrosion protection, which meets the highest C5-M/C5-I requirements of EN ISO 12944-6, ensure that PROFOX actuators have a long life at temperatures from –30 °C to +70 °C.

PROFOX actuators are simple and easy to use. Installation and commissioning are fast and convenient, using either the integral pushbuttons or an intuitive app. The FOX-EYE indicator light and a position indicator on the housing clearly show the actuator status at any time, even from a distance.

“The new PROFOX actuator series is set to lead the market thanks to its unique combination of features,” says AUMA product manager Christoph Edelmann. “It offers unprecedented intelligence, precision, efficiency and flexibility at a very attractive price.”

AUMA Service has reacted to the coronavirus crisis by adding Live Video Support to its service portfolio.

“AUMA actuators are often installed in critical infrastructure,” says Thomas Knecht, Director Global Service at AUMA. “So it is very important that, even in times of crisis, AUMA Service can continue to help our customers quickly and directly to ensure failure-free operation of their plants.”

“We have occasionally used video assistance in the past, and it has proved to be very successful. Many questions or problems can be solved remotely via video, without a service technician having to go on site. To protect both our customers’ and our staff’s health and to help impede further spread of the virus we are now offering this service worldwide.”

If customers have questions about the AUMA actuators in their plant, an experienced AUMA service expert can use a videoconferencing service to connect with them on their smartphone or tablet. Via video, the service expert can then get a good idea of the situation, assist the customer with troubleshooting, and take any necessary action such as ordering spare parts.

This service is available worldwide, through our comprehensive global AUMA service network.

How to request Live Video Support

You can request this new service simply by contacting your local service office or sending an email to service@auma.com.

For fast processing of your request, please include your contact details, the actuator serial number and a short fault description.

You can also request Live Video Support via the AUMA Cloud. In this case you can attach important device data directly to the service request, allowing our service experts to get to work even faster. The video will provide you with detailed instructions.

Why use pneumatic actuators? 

Published

on

Actuators come in many shapes. There is a wide portfolio of actuators in the market, each with different use for different applications. From electrical to pneumatic to hydraulic..The most common type available in the process industry would be the pneumatic type, since these are highly reliable, efficient and also safe. Pneumatic type uses pressurized air for the motion control to convert energy into rotary or linear motion.  Pneumatic actuators are especially used to control the valves where fluids are moved in process industries. 

There are two primary forms of pneumatic rotary actuators , single acting and double acting. They both work to push forward a piston. 

Single-acting types have one port that allows air to flow into the cylinder. The pressure increases and pushes the piston forward or backward. Springs return the piston to its original position, making it ready for another pressure move. 

Double acting type operate without a spring and have two ports. The first application of pressure pushes the piston forward. This is the same in both types. But the second pressure attack pushes the piston back into place. The customer however, should choose, which type he actually needs for the application: with the double type, when there is air loss no safety position required.
For the single acting (spring return) type there is the safety position when there is air loss. 

Airpower actuators have the benefit to use the same body for both types. For the double and single acting type they have same body, which is a major advantage costwise since you need to keep stock just for one type. These can be converted into single-acting by merely inserting pre-stressed springs.
Along with the standard pivoting angle of 90° also available with 180° angle. And the pivoting angle is adjustable from 180° to 120°. 

Another important aspect is the corrosion protection. In order to provide for corrosion protection a quality actuator should be hard anodized in body and caps. In addition, it should be powder coated. This is important for especially critical environments. For the single-acting type the springs should also be plastic coated in order to provide good corrosion protection.
