3 Foam Proportioning & Loose Equipment Product: Williams Pressure Reducing Valve (WPRV/3, 3P, 4 & 4P) Description: Maintains constant pre-set inlet pressure for use in conjunction with the Williams High Head Through/Around The Pump (or comparable) foam systems. Allows any firewater pump to produce suction side foam at virtually ANY positive inlet pressure. As such, the WPRV eliminates need for operator intervention to adjust intake gate valves due to suction pressure fluctuations as a result of changes in pump discharge flow. Thus, the added burden of assuring a maximum pump intake pressure (based on pump discharge pressure) associated with traditional suction side foam systems simply goes away. Additional Applications: Got a CAFS or Balanced Pressure system? The WPRV can provide reduced pump inlet pressures to allow increased engine/pto speed to maintain higher compressor or foam pump output when operating with positive pump inlet pressures. Installed within a discharge line, the WPRV maintains a preset pressure for hand lines or ground monitors independent of higher pump discharge pressures. Features: 3 Modes of Operation: 1. AUTOMATIC Controls pre-set pressure from PSI 2. OPEN Full flow to rated capacity WPRV/3 500 GPM w/ 7 PSI drop WPRV/ GPM w/ 20 PSI drop 3.

5 Foam Proportioning & Loose Equipment Product: Jet Ratio Controllers ( Jet Pumps) Description: Utilizing a small amount of water, this high efficiency venturi-type device moves foam concentrate from a remote storage location to a matched Hydro-Foam nozzle. This all-hydraulic system dramatically simplifies and improves the logistics of moving the high quantities of foam concentrate required to extinguish a large flammable liquid fire. Foam concentrate is delivered from the Jet Ratio Controller to a matched Hydro-Foam nozzle via fire hose. Depending on nozzle and hose size, as well as the percentage of foam mixed (1% or 3%), the distance between the foam supply and Hydro-Foam nozzle can be up to 2,500 feet. Jet Ratio Controllers are supplied in conjunction with matched Hydro-Foam nozzles. Foam concentrate inlet on matched nozzle can be provided with 8 ft. of reinforced clear plastic hose with PVC shut-off valve, and/or metering valve stinger. This configuration allows foam concentrate to be drawn directly from a foam concentrate drum and then delivered efficiently to the nozzle via fire hose. Jet Ratio Controllers are provided with connections at three ports, designated as inlet, discharge and suction. Inlet (female swivel) and discharge (rigid male) has National Hose thread (NST, NH) connections with NPT (M) connection for the concentrate inlet port. Foam concentrate inlet is furnished with standard drum kit, which consists of flexible suction hose, rigid PVC Stinger pipe and shutoff valve. Jet Ratio Controller body is all brass construction. H series jet ratio controllers are available, on special order, for elevated nozzles, or other high back pressure applications. Typical Schematic ThunderStorm AFFF/ATC PRODUCTS J5

7 Foam Proportioning & Loose Equipment Product: 95 gpm Liquid Eductor Description: The Elkhart Eductor is a device used for educting a liquid concentrate solution into the water stream of 1-1/2 coupled fire hose lines. The Eductor is constructed of Armor-Lyte composite material with stainless steel components for resilience and durability. Armor-Lyte is impervious to the corrosion caused by high concentrate detergents, salt water and most chemicals. Each eductor comes equipped with a 1-1/2 F NH female swivel connector input, a 1-1/2 M NH male outlet and a 3/4 male Garden Hose Thread inlet for the concentrate pick-up hose. The Eductor is factory calibrated for pump flow rates of 95gpm (356 lt/m). The Eductor comes complete with three different checkvalves for three different concentrate eduction rates. When attached, the Black checkvalve will educt at a 0.5% rate, the Purple checkvalve will educt at a 1% rate and the Green checkvalve is for educting at a 3% rate. To switch checkvalves on the eductor unit, gently grasp the checkvalve body with pliers or vise grips and unscrew. Carefully screw alternate checkvalve into eductor body, thread to hand-tight. There is no need to over tighten. The Eductor can be used as either an End-of-the-Line or as a Pump Mounted System. The eductor is designed for a nominal operating pressure of between 75 and 150 psi. If proportioning 3%, the s are restricted to a maximum hose length of 150 feet between the eductor and nozzle. However, at ½% and 1% solution rates, the maximum hose lay with 1.50 ID fire hose goes to 200 feet when used with a 95+gpm nozzle. The Eductor comes complete with three different checkvalves for three different concentrate eduction rates. *Armor-Lyte is a registered trademark of Williams Fire and Hazard Control, Inc PRODUCTS J7

8 Foam Proportioning & Loose Equipment Product: Spectrum Inline Eductors Description: Spectrum Inline Foam Eductors provide the simplest and most economical method of introducing a controlled flow of foam concentrate into a pressurized water stream. As opposed to Hydro-Foam Technology, (which is used in conjunction with master stream nozzles) these Venturi- Type foam proportioners are designed to be used in conjunction with a matched constant flow end-of-line device (nozzle), where adequate water pressure is available. Inline foam eductors are capable of operating at inlet pressures as low as 70 psi, but in most cases adequate residual fire fighting pressure at the nozzle requires that the eductor inlet pressure be at least 100 psi, or greater. Spectrum Inline Eductors are rated to flow 60, 95, or psi inlet. Nominal flow rates at other inlet pressures are listed below. Eductor outlet pressure is approximately 65% of inlet pressure. Eductor components, including body, venturi jet and metering orifice are constructed of corrosion-resistant brass. Standard water inlet - NH (F) swivel. Foam solution discharge - NH (M). Complete with clear pvc concentrate pick-up hose with slotted brass stinger ; 1% or 3% fixed orifice; ball check valve.

9 Foam Proportioning & Loose Equipment Product: Spectrum Double Action By-Pass Eductor Description: The Spectrum Double Action By-Pass Foam Eductor provides the versatility of a full-flow water by-pass foam proportioner in conjunction with the simplicity and reduced weight of a standard, single waterway inline eductor. This specialty by-pass type foam venturi transforms any 1.5 handline into a foam proportioning system. Three flow rates are available: 60 gpm; 95 gpm; 125 gpm. Flows are based on 200 psi inlet pressure. The eductor will proportion foam at lower inlet pressures, provided that discharge pressure is not excessive. Positive shut-off metering allows foam proportioning to be adjusted and set from 0.5% to 3%. Body is constructed of durable T6 (black) anodized aluminum. In operation, foam is produced by simply installing the system in the hose line, emersing the concentrate pickup tube into an adequate supply of ThunderStorm AFFF foam concentrate and adjusting the eductor to the foam position. When foam application is no longer needed, there is no need to remove the eductor for application of water only. This conversion is easily accomplished by simply rotating the foam control sleeve to the water setting. The result is an enlarged waterway which allows for water only application. Other Features Include: Positive Shutoff Metering Valve. Integral Concentrate Ball Check Valve. Clear Plastic Concentrate Pick Up Hose with Rigid Stinger.
