Both booster ports remain tightly shut with the soft seating inserts preventing unnecessary air consumption. With large or faster variations in signal flow, the requalizing / bypass valve setting causes them to be registered sooner on the booster ininlet than on its outlet which is connected to the actuator. When the differential pressure obtained exceeds the deadband value of the booster, set by the adjustable equalizing / bypass balve, the diaphragm assembly will move as to open one or other booster port and allow rapid change of pressure within the actuator. When the pressure balance is restored, with the postioner or controller senses that the corrective action is completed, the booster closes and allows the system to resume normal operation with the actuator being fed via the equalizing/bypass valve flow. Installation For maximum perfirmance with both models of booster these should be fitted as close to the actuator as possible. Where multi-boosters are fitted these should be individually connected into the actuator, with separate connections for optimum performance. Air supplies should be clean and dry. A good quality thread jointing compound should be used on all fittings in preference to PTFE sealing tape, which can migrate into the booster units and cause malfunctions.

We are a major Manufacturer, Exporter & Supplier of Air Filter Pressure Regulator. Our range of Air Filter Pressure Regulator includes Air Filter Pressure Regulator (JRC-4) and Air Filter Pressure Regulator (JRC-6). The Air Filter Pressure Regulator is a reliable unit designed for instrumentation. The design is especially well suited to controllers and instruments besides actuators, air cylinders, and a wide range of industrial pneumatic systems and equipment, JRC Air Set is ruggedly designed and constructed and shows excellent performance characteristics. Quality materials are used and each unit is pressure and leak tested, to ensure long and trouble free operation. Specifications Inlet Pressure : Upto 10 kg/cm2 (150 psig)Outlet Pressure : 0 to 120 psig with spring ranges of 0 to 30 psig, 0 to 60 psig and 0 to 120 psigEnd Connections : Inlet/Outlet/Gauge : 1/4" NPT (F)Filter Element : ABS plastic, 25 microns and 5 microns optionFeatures : Higher capacity and power droop, Soft seat construction in both the pressure reducing and relief sections and Aluminium and stainless steel material option. Principle Of Operation : The pressure is set to a desired value by compressing the range spring by adjusting knob or screw. This causes the pin to move downwards, opening the supply valve and allowing air flow. Filtration : The air first enters the inlet port and passes through the filter element where solid particles are trapped. Water and oil particles are thrown against the inside wall of the bowl by centrifugal force. The liquid particles collect in the bottom of the bowl, which can be drained off regularly by opening the DRAIN PLUG.Regulation : The clean air passes through the supply valve and the pressure at the outlet builds up against the control diaphragm and closes the valve until the equilibrium is achieved. This equilibrium or set pressure is maintained under changes in operating conditions in the following manner.Downstream pressure drop : A drop in downstream pressure reduces the diaphragm pressure force, upsetting the equilibrium condition. This unbalance causes the supply valve to open until the pressure builds up once more to the equilibrium.Downstream pressure increase : A sudden increase in downstream pressure acts on the diaphragm, causing the relief seat in the diaphragm assembly to lift and open. The excess pressure drops almost instantaneously to the equilibrium value, at which point the relief valve closes.Changes in forward flow : Under forward flow conditions the range spring force is balanced by the diaphragm pressure force, with the supply valve open just enough to maintain the requited equilibrium output pressure. When high flow occurs, a specially designed aspirator helps maintain downstream pressure and compensates for droop. Design Features Self-relievingRugged, Corrosion - resistant ConstructionVarious output Pressure ranges availableFilter size options available to suit different applicationsSeveral mounting options including mounting bracketEconomic designMinimum moving parts Performance Features Superior regulation characteristicsLow droopExcellent stability and repeatabilityEffect of supply pressure variation is negligibleSmooth action and stable control over full rangeIdeal for instrument air pressure regulation Associated Benefits Utilizes over 36 years of engineering, design & application expertiseLong and trouble free serviceAssured product Quality Maintenance The filter element is readily accessible by removing the dripwel bowl and can be cleaned by dipping in kerosene or any similar solvent. The Airset has a drain cock at the bottom edge of the dripwell which permits drainage when the unit is mounted in vertical or panel-mounted horizontal position. J. R. Conval Engineers have been designed to give long and trouble-free service with little or no maintenance. In the event of on-site servicing a spares kit may be provided for easy replacement, reducing downtime.
