Custom Fire Apparatus, Inc. All intakes shall be furnished with suitable closures capable of withstanding 500 PSI, threaded caps shall be chrome plated brass, rocker lug 3" and smaller, long handled larger than 3". SUCTION INLET VALVE STANDARDS (WHERE OPTIONALLY SPECIFIED) Following optionally specified 3" or larger gated intakes (except the tank -to -pump intake) shall include a remote controlled valve mechanism that shall not permit changing the position of the flow regulating element of the valve from full close to full open, or vice versa, in less than 3 seconds. Where air type actuators are employed, they shall include dual (2-each) adjustable needle valve restrictors, bench set/tested, so as to facilitate the slow movement. Where manual gear or electric gear style actuators are employed, the crank or motor shall regulate movement speed. SHORT SUCTION TUBE The specified side pump suction inlet(s) shall be of minimum length to allow for exterior stacking of adapters or pre -connected hose. INLET BLEEDER VALVES Where specified, each gated intake shall be equipped with a bleeder valve located inside pump compartment (inside rear compartment -for rear suctions), upstream gate valve, with remote bleeder control in close proximity to the intake. The gated inlet bleeders shall consist of:.75" high pressure flexible hose assemblies extending between suction valve and bleeder valve, .75" cast bronze or stainless steel bleeder valve, exterior bleeder valve control handle, and an engraved or printed identification label. Bleeder controls for side gated inlets are to be located below the inlet, in a single row immediately above the running board/floor level. Bleeder controls for optionally specified rear inlets are to be located below the inlet, above the tailboard level. The bleeder valves shall be Innovative Control, "lift -handle" style equipped with chrome plated lever control handles, which are in the down position when closed. HOSE THREADS Where specified, all screw-on/off threads shall be NST (National Standard Threads), all "sexless" couplings shall be Storz. PUMP DISCHARGE OUTLET CONTROLS AND ACTUATORS All discharge valves shall have operating controls and actuators that allow the valve to be positioned incrementally from closed to full open, and locked in any selected position. Each valve control is to be adjacent to its respective pressure instrument. Each of the specified 3" diameter or larger discharge valves are to have an operating mechanism which shall not permit changing the position of the flow regulating element of the valve from full close to full open, or vice versa, in less than 3 seconds. 07/26/22 -92-
