This state-of-the-art facility has been designed to replace the Alison Air Valves Test Stand Assembly part number 23002225/01-088-4202, NSN 492001-088-4202 and associated Technical Manual documentation TO 33D4-6-183-1 which is now obsolete. The test facility consists of a fully mobile brushed stainless steel cabinet integral test/ viewing chamber with an ergonomically angled control panel containing all necessary instrumentation, pre-configured for each of the units being tested and for observing test responses. The cabinet incorporates the compressed air supply system, filtration, pipe work, vacuum vessel and all instrumentation. Double doors both front and rear allows easy access for routine maintenance and calibration. The facility has been specifically designed to offer the following capability: • Opening and closing tests. • Internal and external leakage tests. • Flow tests. • Cycling tests. The unit will be C.E. certified to meet current legislation and EU directives. To operate, the facility must be connected to a suitable local mains electrical 3 phase supply. Part Marking The air & anti-Icing valve facility is individually identified as follows: • Part Number. • NATO Stock Number (NSN). • Description. • Individual Serial number.
