Suite of Secondary Suspension Products for the Rail Sector

Giada Bianchessi 964 Views , , ,

Norgren expands its secondary suspension portfolio, dedicated to the rail sector, with a mechanical levelling valve, Average Load Valve and Double Check Valve. These three complementary components ensure smooth system operation and longer maintenance intervals.

Norgren has added three new products to its rail specific secondary suspension portfolio, further enhancing its “one-stop shop” capability for rail customers. The new trio of products consists of a mechanical levelling valve, together with complementary average load valve and double check valve solutions. All of them provide good lifecycle performance, flexible installation and ongoing maintenance, and cost reductions, helping to drive improved operational efficiencies. Robust, proven and helping to support more efficient maintenance regimes, the levelling valve, alongside the double check and average load valves, provide cost-effective, safe, long-lasting and reliable solutions for an essential part of the train operation and also help to positively influence the travelling experience for passengers. The development of these three new products to Norgren’s portfolio enables the company to offer a comprehensive range of secondary suspension products which also include the VT ball valve range, 19S pressure sensor and LVP50 proportional control valve.

Levelling valve with reliable repeatability

Following in-depth industry research, Norgren has developed a robust and high performing mechanical levelling valve VRSS1000 series with reliable repeatability over its life proven through extensive testing and validation, which will enable extended maintenance periods to be implemented by the operator. The mechanical levelling valve offers a guaranteed solution when it comes to the inflation and deflation control of the suspension bellows to ensure the car is kept level under changing load and track conditions.

Norgren offers a wide range of products for secondary air suspensions systems, all of them being rail certified.

Instant feedback on the pressure status

Complementing the performance of the mechanical levelling valve are the average load valve VRSS3000 series and the double check valve VRSS2000 series (also known as a compensation valve). Both offer additional functionality. The average load valve is available in flanged versions or with direct connections. The inclusion of pneumatic pressure test ports on the double check valve is a safety-driven function that allows for quick and safe system pressure checks for maintenance personnel. The addition of an electronic pressure sensor function on the double check valve can provide instant feedback on the pressure status of the train system, allowing adjustments to be made to the braking systems when required.
