EVOL Air Pressure Regulator is a high precision, single-stage diaphragm air pressure regulator. Even with feature of SS316 construction, it is still an economical and ideal choice for pressure reduction. Thus, the regulator is suitable for any process that requires precise regulation of air pressure in pipes and vessels.
In EVOL Technologies, there are five types of air pressure regulator available:
(i) F.R.L combination (ii) Filter regulator (iii) Filter (iv) Regulator (v) Lubricator

Filter and Regulator
WORKING PRINCIPLE
When the adjusting screw is
turned clockwise, the set point
pressure (P1) is greater than the
pressure under diaphragm (P2)
The pressure is now:
P1 > P2
Set point pressure > Pressure
under diaphragm
The spring opens the valve
assembly and allows the air
passes through
The air inlet passes through the
filter, which removes dirt
particles in the incoming air (Applicable on the model with filter only)
If the outlet pressure is higher
than the set point pressure, the
diaphragm transfers the high
force to ventilation port
The ventilation port releases the
excess air to achieve an
equilibrium force
The pressure is now achieved:
P1 = P2
Set point pressure = Pressure
under diaphragm
The set point pressure is
maintained and the air inlet
continues to pass through
The pressure is now achieved:
P1 = P2
Set point pressure = Pressure
under diaphragm

Lubricator
Lubricator is assembled after:
(i) FR
(ii) Filter
(iii) Regulator
It works by injecting small
particles of oil into the moving
air stream of a pneumatic system
As air flows from regulator, some
air is divided from the main
orifice and is diverted to apply
pressure on the oil reservoir
The force pushes the oil up
through siphon tube to sight
feed dome
In the lubricator, the capacity
valve opens in proportion to the
air flow
When the capacity valve opens,
the oil drips into the air
downstream
Sight feed dome is a polyhedron
bowl, which can be used to view
the oil flow into air stream
Then, the capacity valve
regulates oil flow in direct ratio
to the air flow increase
The capacity valve atomizes the
air and oil mixture creating a fine
mist of lubricant into the air
stream
