Customer Requirement

NSF Controls was approached by Landis + Gyr to improve its prepayment and smart meter gas valve design without altering function. A smaller, lighter format was required with exceptional reliability whilst remaining cost competitive.

NSF Controls Solutions

NSF’s engineers developed one of our standard magnetic latching solenoids to contain a longer coil which produced higher forces and increased performance. The solenoid was then designed to over travel to ensure latching and to pressurise the seal against the sealing face. Bayonet interfaces and dust bags were later introduced when the overall gas valve meter was redesigned by the customer.


The end result is a shut-off valve weighing 80% less, with exceptional sealing pressure, flow rate, compact size and now a proven track record of over nine million installations.
