International pneumatic motion and fluid control technology provider Norgren has launched a new automatic drain valve for the rail sector, an innovative product which delivers engineering advantage by removing condensate from a compressed air system without the need for a power supply.
Based on a newly developed 2/2 way level controlled valve principle, the automatic drain valve discharges quickly and effectively, using a direct acting ballcock system to sense when the condensate reservoir has reached the required level.
As the valve works mechanically, there is no need for an electricity supply, meaning it is ideally suited to installations where power is not available, is too expensive to install or is unstable. Functioning without the need for electricity means the automatic drain valve can reduce operating costs and is more environmentally friendly.
Suitable for use with compressed air systems operating at up to a maximum of 100m³ per minute, one model can be used for most applications, which can help to reduce stockholding costs for the rail operator. The valve can be used in ambient temperatures of -40°C to 80°C and works with system pressures of 3bar to 16bar. An electric heater is available for low temperature applications, though the electric heater would require its own power supply.
Easy to install and service, the compactly designed drain valve has top and side inlets for maximum flexibility when siting the product. Manufactured with a robust aluminium housing, the automatic drain valve has demonstrated reliability in lengthy vehicle trials and is proven to extend the life cycle of a compressed air system.
Additional features of the automatic drain valve include an integrated strainer to ensure the condensate discharge is free from debris.
Norgren global rail sector head Mark Wrigley said: "We are committed to the development of innovative products tailored to meet the unique challenges of the rail sector. Our new automatic drain valve demonstrates how we listen and respond to those challenges, offering our customers engineering advantage in every product we bring to market."
