Divya Control Elements Private Limited

Makarpura Industrial Estate GIDC, Vadodara, Gujarat

Features

• Used at the downstream of a pressure regulator to protect the system from over-pressure.
• Wide array of springs to meet majority of application requirements.
• Provision to match blow down ring & disc in case, the relief pressure is to be re-set for proper popping.
• Simple design ensuring long life & functional reliability.

OperationThe primary air enters the inlet port and passes through the Filter element where solid particles are trapped. Water and oil particles are thrown against inside wall of the bowl by centrifugal force The liquid particles run down and collect into the bottom of the bowl. Clean air, then flows the upward
into the regulator section. Here, the flow is restricted to establish the desire pressure at the outlet. The regulated air, pressure acting under neath the diaphragm is balanced by the force of the adjustment spring. When the pressure rises above the set point, it pushes the diaphragm away from the relief hole and the excess air finds its way to the atmosphere through the bleed hole, till it again reaches the set point pressure.

Ensures Optimum Performance & ReliabilityThe VISHAL Air Set is a combined filter cum regulator unit with an appreciable capacity & low pressure droop. (Typical case: at 100 psig i/p and 20 psig o/p, capacity is 4.0 scfm with a 1.5 psig droop)

Features

• One piece pressure reducing & relief valve.
• Tight sealing soft seat.
• Simplified design and reduced number of moving parts.
• Simple & reduced maintenance.
• No lubrication required.
• Wrench adjustable, available in various ranges.
• Fast & sensitive response.
• High Filtration efficiency.
• Filter readily accessible.

Regulation CharacteristicsKeeping the Air Flow constant, the variation in the set Output Pressure (o/p), with reference to the changes in the Input Pressure (i/p) defines the Pressure Regulation Characteristics of a Filter Pressure Regulator.
Vishal Air Set successfully maintains the variations, in the Output Pressure within Tolerable Limits of max. 5% (In case of Low Range) & 10% (In case of High Range), even if the change in the Input Pressure is ± 50% taking care, the same is kept higher by min. 6% of the set output pressure 
Flow CharacteristicsKeeping the Inlet Pressure constant, the Output Pressure is set & as the flow increases, the droop which occurs across the valve with regards to flow in the characteristics of flow for a Filter Pressure Regulator. Pressure Droop dampens the performance of an Air Set.
Vishal Air Set successfully reduces the Pressure Droop by a Sensing Hole, which connects the chamber beneath the diaphragm to the port, wherein the valve is seated. As the flow increases, the droop occurs which in turn forces the diaphragm (due to spring load) to push open the valve, thereby compensating for the Pressure Droop.
A large port is responsible for higher discharge of air through the valve for quick recovery of the droop.
