2 Baker Maric Flow Control ValvesEver since water has been piped there has been adefinite need for a practical, accurate, self cleaningand inexpensive form of automatic flow control. The“Baker Maric Flow Control Valve” was developedto fill all these requirements and more.The Baker Maric Flow Control Valve has been usedsuccessfully in many countries since 1960 to give aCONSTANT FLOW irrespective of changing waterpressures. The initial valve cost is quickly recovered byreducing wastage of a valuable natural resource.In the South African Mining Industry the Baker Maricis used exclusively as a water saving device. TheWafer pattern fits in between flanges and is totallytamper proof and can handle dirty service water.The Baker Maric Flow Control consists of:• A precision moulded flexible control ring• A precision machined recess to accept the control ring.• Body manufactured to rigid engineering standards.PRINCIPLE OF OPERATIONThe flexible control ring is made from “Nitrile Butadine Rubber”meticulously compounded to pass exacting flow tests. The body of thevalve may be constructed of various materials including Brass, PVCand Stainless Steel.Accuracy: 10 %HIGH PRESSUREFlexible ring rollsdown tapered seatunder pressuredecreasingorifice, givingconstant flow.LOW PRESSUREFlexible ring innormal position.Maximum orifice.IDENTIFICATIONAll valves are stamped with rate of flow in litres per minute, and anarrow indicating direction of flow.PROPERTIES• Self cleaning - the flexing of the control ring during operationprevents the build up of mineral salts and rust flakes.• Odour free, taste free and non toxic.• Life expectancy - in excess of ten years• Automatic - responds instantly to changes in water pressure.• Self regulating - install and forget.• Economical - low initial cost is quickly recovered.• Compact - easily installed• Maximum operating temperature of 75ºC.• Standard maximum operating pressure 16 bar.(Higher pressure available on request)EXAMPLES OF APPLICATIONIrrigation, multi-storey buildings, homes, schools, Industrial -commercial and mining.CONCLUSIONWater is rapidly becoming more and more expensive. Start savingtoday by installing Baker Maric Flow Control Valves.The illustrations in this catalogue are subject to modifications without notice.premierP.O.

ACROSS VALVEQuestion: What will be the head loss across theBaker Valve?Answer: At least 140 kPa, or between 140 and 1 000kPa if the system is designed and operating correctly.This is because the function of our “PRECISION” rangeof valves is to control the flow when P.D. across the valveis within this range. Therefore, to achieve full rated flow,(accurate to within +/- 10%), the installation must providefor inlet to be at least 140 kPa above outlet pressure.To Calculate Headloss:Assume valve is controlling flow as required. Determinewhat pressure will be at the inlet, and what pressurewill be at the outlet. The P.D. will then simply be thedifference between inlet and outlet above. Should thiswork out to be less than 140 or greater than 1 000 kPa,then this PRECISION valve will not provide full flow andthe installation will either require altering, or the useof Low Pressure Valves (40 - 200 kPa) or High PressureValves (250 - 1 500kPa).Performance GraphTYPICAL OF ALL PRECISION VALVES IRRESPECTIVE OF BODY SIZE OR FLOWRATE120%110%Rated Flow100%Expressedas % of fullrated flow90%80%70%60%kPa 100 200 300 400 500 600 700 800 900 1000 1100The illustrations in this catalogue are subject to modifications without notice.premierP.O.
