1/8" Regulator

Syntesi® pressure regulator is based on the rolling diaphragm principle,
which offers numerous advantages compared to systems using a flat
diaphragm:
• Increased stroke, allowing wider valve aperture and hence greater
flow rate.
• Decreased dynamic and pick-up friction, and hence quicker response
and enhanced sensitivity.
• Greater accuracy in maintaining the pressure setting, both with both
variable flow rates and different supply pressures.
The regulator includes a compensation system that keeps the pressure
setting virtually constant, even when the upstream pressure changes.
This is achieved mainly by the design of the valve, which is pneumatically
balanced.
If the downstream pressure rises above the threshold value, the air is
discharged (relief valve) until it drops below the maximum value.
A special device relieves downstream pressure rapidly when the
upstream pressure drops to zero. This means the regulator can be
positioned between a valve and a cylinder because the air can flow in
both directions, towards the cylinder with regulated pressure, or return
towards the valve during relief.
The knob is the push-lock type – once the pressure has been set, press it
and it locks in position. In this position you can pull out the plate and
attach two padlocks on size 1 or three padlocks on size 2 in order to
avoid possible tampering. On the front and back there is a port (1/8”
for size 1 and 1/4” size 2) that can be used with pressure gauges,
pressure switches or as an additional regulated air intake.
