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 psig
• End Connections : Inlet/Outlet/Gauge : 1/4" NPT (F)
• Filter Element : ABS plastic, 25 microns and 5 microns option
• Features : 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-relieving
• Rugged, Corrosion - resistant Construction
• Various output Pressure ranges available
• Filter size options available to suit different applications
• Several mounting options including mounting bracket
• Economic design
• Minimum moving parts

Performance Features

• Superior regulation characteristics
• Low droop
• Excellent stability and repeatability
• Effect of supply pressure variation is negligible
• Smooth action and stable control over full range
• Ideal for instrument air pressure regulation

Associated Benefits

• Utilizes over 36 years of engineering, design & application expertise
• Long and trouble free service
• Assured product Quality

MaintenanceThe 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.
