The valve functions as a relay between the brake pedal signal and the brake chambers, helping the service brakes apply quickly and consistently across the vehicle. It features a 2 SUP \/ 2 DEL (H) body configuration with 1\/2-14 NPT supply ports and 1\/2-14 NPT delivery ports, plus a 1\/4-18 NPT control or secondary service port to integrate with standard air brake plumbing. The unit incorporates an exhaust adapter without silencer and is specified with a crack pressure of 5.5 PSI for predictable operation. With an operating temperature range from -40 degrees Fahrenheit to 200 degrees Fahrenheit (-40 degrees Celsius to 93 degrees Celsius), it is suited to a wide range of on-road conditions. Supplied as an aftermarket new component, it is used as a service replacement for existing Bendix R-12 relay valves.","brand":"BENDIX","offers":[{"title":"Default Title","offer_id":49057068744955,"sku":"K028453","price":593.69,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/6030\/4123\/files\/49940.jpg?v=1783513140","url":"https:\/\/www.tranzmile.com\/products\/valve-relay-r12-k028453","provider":"Tranzmile Truck \u0026 Trailer Parts","version":"1.0","type":"link"}
