Buckeye Bladder Tanks store foam concentrate and are one component of a Balanced Pressure Foam System. They require no external power, other than a supply of water to ensure proper operation. The Vertical and Horizontal Bladder tanks are designed and constructed in accordance with the latest revisions to ASME code, Section VIII for unfired pressure vessels. They have a working pressure of 175 PSI and they are tested to one and one half times this pressure.
The Buckeye Model FAM - PO Ratio Flow Controller is a proportioning device designed to meter the correct amount of foam concentrate into the water stream over a wide range of flows and pressures. These units are used in conjunction with either a bladder tank or a foam pump proportioning system. The operating principle of the controller is based upon the use of a modified venturi. As the water passes through the inlet jet, a reduction in pressure in the annular area is created. This reduction allows the metering of the foam concentrate into the water stream through the foam concentrate metering orifice.
In-Line educators (line proportioners) can present a simple, cost-effective method To proportion foam concentrate and water at the proper percentage. Buckeye offers a full range of line proportioners in corrosion resistant brass. Line proportioners are constant flow devices that produce accurate proportioning of foam concentrate at a specified flow and pressure. It is therefore critical to match the line proportioner with all downstream devices, including all friction loss associated with delivering that flow to the particular nozzle(s) at the design pressure. Line proportioners are usually portable devices, however, with proper considerations they can be used in fixed system applications.
The actuator is provided with a water inlet shut of valve to facilitate the resetting of the valve after actuation. Ensure that this valve is lift open when system is placed into service .Failure of the system could result if the valve is left closed
