This valve has the same features as our standard Q.R.B. but with the added advantage of having an outside screw and yoke which isolates the threads of  the stem from the product being hauled.  The Betts Q.R.B. Hydrolet Valve with the exclusive quick-removable bonnet, is designed for use on transport tanks hauling a variety of products, where easy dismantling for cleaning and inspection is essential. The valve is available in the three styles shown below in 3” and 4” sizes with flanged or threaded outlets.  The valve is constructed of 316 stainless for compatibility with a wide range of products.
