AUMA Electric Actuators for Water Distribution and Wastewater Treatment

Drinking water abstraction and distribution, as well as sewage disposal and purification, are basic prerequisites for community infrastructure development. Security of supply is crucial for any modern water industry.

Piping of different lengths and nominal diameters must be automated with a multitude of valve types. From potable water production and distribution, to sewage treatment, to water treatment systems, AUMA actuators automate valves of any size and design. AUMA has been building electric actuators and valve gearboxes for over 50 years, and is one of the leading manufacturers in the water industry. AUMA is well implanted due to their broad product portfolio including multi-turn, part-turn, and linear actuators. In combination with high corrosion protection, they guarantee a long service life, low in maintenance.

Flowserve ValveSight Diagnostic Solution for Control Valves

The video shared this week, from Flowserve, provides an overview of their ValveSight real time online diagnostic solution for use with control valves and associated actuators, positioners and controls. ValveSight enables operators to keep valves in service longer by detecting potential failures before they occur. The system provides a deep level of monitoring and diagnostic functions which are described in the video. Reducing unplanned downtime is a common goal among all facilities and plant operators. Check out the short video, and share your questions about the system with an application specialist.

Using Pneumatic Volume Boosters on Valve Systems

Pneumatic volume booster
(Fairchild)

A pneumatic air volume booster reproduces a low flow control signal with a higher regulated flow output pressure. It uses an unregulated input pressure to maintain a regulated output pressure under flowing and non-flowing conditions.

The regulated output of a pneumatic air volume booster can be any of the following:

• A direct reproduction of the pneumatic control signal
• A multiple of the pneumatic control signal
• A fraction of the pneumatic control signal

Volume boosters are also used in conjunction with valve positioners on large control valve actuators to provide faster response than possible with the valve positioner alone. Deadband within the volume booster allows the positioner to make small incremental valve positioner changes in a highly stable manor without activating the volume booster valves.

The following video provides and in-depth understanding on how to use pneumatic volume boosters with valve actuator systems and how to optimize performance.
