The flow capacity of valves, connectors and other components in pneumatic systems is often expressed in Cv. (See, “What is the flow coefficient Cv?“) However, other methods and standards are also available to express flow capacity. Here are some important alternatives. Sonic conductance In place of Cv, some manufacturers choose to publish the sonic conductance, […]
Nitra miniature solenoid valves and manifolds for low-flow needs
NITRA GVP series pneumatic miniature solenoid valves from AutomationDirect are an excellent choice for many automation applications with low flow requirements. These two- and three-port valves are typically used for on/off flow control or with single-acting cylinders. Starting at $26.00, GVP series 12 or 24 Vdc solenoid valves are available in 10 and 15mm valve […]
What is the flow coefficient Cv?
In the pneumatic industry, Cv is one standard for expressing the flow capacity of devices used in pneumatic systems. However, there are multiple other standards that also express flow capacity, including effective orifice size and normal liters per minute, as well as measurements of actual flow rates at specific pressure differentials. These methods are not […]
New digitization solutions from Festo advance Rockwell Automation’s IIoT Initiatives
At Automation Fair 2018 this week, Festo will introduce new solutions that advance Rockwell Automation’s data-driven manufacturing and processing initiatives. See Festo at Automation Fair, November 14 and 15, in Booth #411) “The future of optimum overall equipment effectiveness and energy efficiency will rely on a collaborative maintenance environment and on intelligent devices that deliver real-time […]
Exhaust valve from Aventics ensures reliable, standardized safety
Safety is always the number one priority for industrial manufacturers. With its new safety valve, Aventics has expanded its range of products in this area. Users can integrate it modularly into AS series maintenance units or position it flexibly as a stand-alone product. The company’s new S3-SV exhaust valve ensures reliable, standardized safety for both personnel […]
Electro-pneumatic pressure regulating valve features low energy consumption
The sub-base mounted EV03 electropneumatic (E/P) pressure regulating valve from Aventics features extremely low energy consumption and can guarantee pressure control during a power loss. Depending on the version, maximum power generation is between 160 to 220 mA. The EV03 also offers precision, with hysteresis as low as 0.7 psi, and flow up to 0.88 […]
Festo’s VTEM Motion Terminal simplifies IoT modularity and flexibility
At IMTS this week, Festo showcased its VTEM Motion Terminal and the benefits Industry 4.0 enabled products like this offer to OEMs. The VTEM Motion Terminal, which began shipping earlier this year, is a revolutionary cyber-physical system (CPS) that embodies the modularity and insights into industrial data envisioned by Industry 4.0. Ten downloadable apps are immediately […]
Pilot-operated check valves from Eisele ensure safe pneumatic cylinder holding
Eisele Connectors’ pilot-operated check valves are part of the company’s Basic Line and can be used in combination with pneumatic cylinders. They enable flow in one direction, which in return blocks the flow in the opposite direction: thus preventing pneumatic cylinders from unintentionally deaerating in the event of a pressure drop. Because they prevent sudden […]
Micro solenoid valves from Koganei are “world’s smallest” says the company
Koganei USA’s 005 series micro three-port solenoid valve is the world’s smallest direct acting valve, say Koganei representatives. The tiny and lightweight valves are perfect for compact devices and equipment used in bio-tech, analytical, and semiconductor manufacturing. Two styles available with either connector or pin types of wiring specifications. They can be mounted in two […]
Clippard PTFE media isolation valves provide custom solutions
Clippard’s media isolation valves are solenoid-operated devices that use a flexible diaphragm to isolate the actuation mechanism from the fluid path. Media isolation valves are commonly used for a wide variety of applications, including those that require precise, repeatable dispensing of media. All wetted areas of the valve are PTFE, making this series suitable for use with corrosive […]
