WATER STOP VALVE FOR DESCALING SYSTEM - IS USE OF LOW WATER PRESSURE PRE-FILL FUNCTION A STANDARD FEATURE IN A MODERN DESCALING SUSTEM, IN ORDER TO ELIMINATE HUDRAULIC SHOCK WHEN INITIATING HIGH PRESSURE SPRAYING THROUGH AN OPEN HEADER. BUT THE LOW PRESSURE WATER CONTINUOUSLY CHARGED THROUGH THE OPEN DESCALING NOZZLES CAN CAUSE UNDESIRED METALLUGICAL EFFECTS DUE TO THE UNCONTROLLED COOLING ESPECIALLY WHEN ROLLING CRITICAL PLATES (API-PIPE OR STAINLESS STEEL GRADES) DURING A THERMO MACHANICAL CONTROL PROCESS (TMCP) THIS INSTALLATION OF THE NEW LECHLER WSV WATER STOP VALVE FOR SCALEMASTER DESCALING NOZZLES IN FRONT OF EVERY NOZZLE PREVENTS A WATER FLOW THROUGH THE NOZZLE BELOW A WATER PRESSURE OF 8 BAR. IT IS A CHECK VALVE WHICH IS COMBINED WITH THE STANDARD STABILIZER UNIT. ITS FEATURES ARE ALL THE WSV COMES WITH A FILTER; VALVE AND STABILIZER UNITS SEPARATE ALLOWING USE OF STANDARD STABILIZERS; MATERIAL COMPLETELY MADE FROM STAINLESS STEEL; AND METALLIC SEALING. ADVANTAGES AND BENEFITS: NO SINGNIFICANT CHANGES OF NOZZLE SPRAY CHARACTERISTICS (WIDTH, THICKNESS, LIQUID DISTRIBUTION); VERY LOW IMPACT LOSS OF ONLY APPROX 13% (WITH MEDIUM NOZZLE FLOW SIZE); VERY LOW WATER FLOW LOSS OF ONLY APPROX 5% (WITH MEDIUM NOZZLE FLOW SIZE); NO MODIFICATIONS OF HEADER REQUIRED; VERY LARGE INTERNAL FREE PASSAGES FOR CLOGGING GREE OPERATION; AND SIMPLE DESIGN, ALL COMPONENTS EASY TO REPLACE.

SPRAYING SYSTEMS FOR MINUTE VOLUME APPLICATION - MOISTENING MOVING SURFACE LIKE BANDS AND BELTS ALWAYS PRESENTED A PLETHORA OF PROBLEMS RELATING TO THE EXACT QUANTITY OF FLUID VARIOSPRAY ELECTRONICALLY CONTROLLED NOZZLE-BASED SPRAYING SYSTEM HYDRAULIC AND PENEUMATIC-PRESENTS THE PERFECT SOLUTION. VARIO SPRAY HDRAULIC ENABLES ATOMISATION OF MINUTE QUANTITIES OF LIQUID VIA HYDRAULIC FLAT-SPRAY NOZZLES, EVERY FLAT SPRAY NOZZLE HAS ITS OWN UPSTREAM TIMING VALVE WITH CONSTANCY WORKING FREQUENCY OF 48 CPS, THE VOLUMETRIC FLOW THROUGHT THE NOZZLE IS ALTERED BY CHANGING THE CONSTANT-FREQUENCY SPRAY PAUSE-DURATION RATIO (DUTY CYCLE) DEPENDING ON THE SELECTED SIZE OF NOZZLE IT YIELD VOLUMETRIC FLOW RATES THAT ARE AS MUCH AS EIGHT TIMES LOWER THAN THOSE THAT CAN BE ATTAINED USING CONVENTIONAL HYDRAULIC FLAT SPRAY NOZZLES, IT EMPLOY PNEUMATIC SPRAY TIPS PROVIDING DIVERSE SPRAY GEOMETRIES, THE SPRAY/PAUSE-DURATION RATIO IS SET ON THE SYSTEM'S MASTER CLOCK (IMPULSE GENERATOR) BY EITHER A POTENNTIOMETER OR AN EXTERNAL CONTROL VOLTAGE A SINGLE MASTERS CLOCK SUFFICES FOR THE INDIVIDUAL CONTROL OF AS MANY AS EIGHT VALVES. IT COMPRISE OF THE MASTER CLOCK, THE CABLING AND THE SPRAY BEAM WITH ITS INTERGRAGED VALVES AND CORRESPONDING PNEUMATIC NOZZLES
