New Valve from Norgren Provides Ultimate in Freeze Protection

Norgren has introduced a new high-performance valve for the international rail sector, which automatically drains onboard water systems as soon as the water temperature reaches freezing point.

Norgren, an international market leader in pneumatic motion and fluid control technology, has introduced a new high-performance valve for the international rail sector, which automatically drains onboard water systems as soon as the water temperature reaches freezing point.

While other products on the market measure the ambient temperature around the valve – running the risk of emptying the system even when it is not in danger of freezing – Norgren’s new freeze protection valve creates ‘Engineering Advantage’ by rapidly detecting the temperature of the medium flowing through the valve itself, delivering improved accuracy and quicker response times.

Norgren’s freeze protection valve has been specifically designed for endurance in even the most demanding environments, with the aim of minimising service intervals, delivering both time and cost savings.

The 2/2 solenoid valve can override the close function, so the system can be refilled instantly when required – reducing both waste water and the time taken to get the train back into service.

Further savings are created through reduced energy consumption - the valve does not need a heater for the override function, as existing technology on the market does – while the product maintains a highly stable temperature set point for more than 10 years.

The freeze protection valve combines a Norgren 2/2 diaphragm solenoid valve, which has been extensively proven in the exacting environments found in the rail sector, with a highly reliable temperature sensing element.

Mark Wrigley, Global Sector Head – Rail at Norgren, explained: “Technical excellence has always been at the heart of Norgren’s operations, and our freeze protection valve is a testament to this. The valve is connected into the existing pipework, meaning its temperature sensing section can be replaced without needing to disassemble the entire valve and surrounding pipework. It is another example of the many innovations being introduced to the rail sector by Norgren which are delivering optimised performance and service life alongside reduced maintenance and running costs.”

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs. The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs. Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these p

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications. The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications. “We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner E


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference. The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection. The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
