Air valves and sizing software from USA Val-Matic manufactures a comprehen- sive air valve product line. From the smallest simple lever air release valve to the largest surge-suppression combina- tion air valve, all are provided as stand- ard with type 316 stainless steel trim and floats ranging in sizes from ½" to 42". The company has a complete range of air valves certified to NSF/ANSI 61

the system is loaded from a transport container, such as a wire box. Tubes can also be machined in pairs, even if the geometries are different. A special version of the bending solution is a robot that grasps the right-hand or left-hand bending machine. It detaches the tube from the magazine and inserts it, correctly positioned, in the clamping device. This is where the bending robot processes the tube and sets it down, also in the correct position. The tubes may even have been fitted on both ends with connection elements. At FABTECH in Atlanta, USA, transfluid presented its t bend DB 630 CNC R/L VE right-hand/left-hand bending machine with turning head for tubes of up to 30mm diameter. transfluid Maschinenbau GmbH – Germany The program will also calculate the collapse pressure, slope and gravity flow in the pipe. Recommendations are given for air valve locations, sizes and model numbers for pipeline and pump discharge locations. Val-Matic Valve & Manufacturing Corp – USA valves@valmatic.com www.valmatic.com for potable water use and NSF/ANSI 372 for lead-free products, material and components, with a few air valves also UL-approved for use in fire protection. Val-Matic air valves are produced in compliance with the AWWA C512 standard, and are manufactured under a certified ISO 9001 quality system. The company’s web-based Air Valve Sizing Program is designed to aid in selecting air valves along a pipeline. Users are able to enter and save design information specific to their pump, water pipeline or waste-water force main to calculate the locations and sizes of AWWA air valves.

Dynamic two-directional tube bending transfluid presented its highly dynamic two-directional tube bending machine at FABTECH in November.

is required for complex geometries. An adaptable bending solution provides new options to achieve this, even if there are restrictions caused by structural issues. For challenges of this kind, transfluid has developed its t bend tube bending machine with turning head. Suitable for any tube diameter, the transfluid system allows efficient right- hand and left-hand turning. Especially when machining small-diameter tubes, the capability to change the bending direction quickly ensures a time advantage. All axes of the special bending system are electrically driven with servo technology, and each bending head comes as standard with two tool levels. transfluid also offers its bending system in an automated option for improved runtimes without manpower. To achieve this, simple magazines are used to feed the supply of components, and

Flexibility is critical in cases in which right-hand and left-hand tube bending

With the t bend DB 630-CNC-R/L-VE with turning head, transfluid offers right-hand or left-hand tube bending without the risk of collision, even for demanding geometries
