Proportional Pressure
Control Valves
Three way, closed loop proportional valves with integrated
25 micron filters, typically used to control the pilot pressure
on high pressure dome loaded regulators. Ideally suited
to control the pressure on PET blowing systems and gas
pressure control on laser cutting machine tools. Proven
technology, compatible with most common industrial gases.
> Port sizes: 1/4" or flange mounted directly
on dome loaded regulator
> Pressure range: Up to 420 bar
> Temperature range: -20 to +80°C
> Control signal: 4-20 mA or 0-10V
> Internal closed loop control
> Body Materials: Brass or Aluminium bronze
Dome Loaded Regulators
Dome loaded regulators control the outlet pressure over a
range of varying inlet pressures and flows. Force is applied to
the control element (diaphragm or piston) by pressure inside the
dome of the regulator. The pilot pressure can be applied from a
proportional valve, or a small low flow spring loaded regulator.
> Particularly suited to high flow applications
> Can be remotely electrically adjusted
by using a proportional valve
> Port sizes; 3/8" to 3"
> Pressure range; 100 to 420 bar
> Flow rate: up to 10 000 Nm3/h
> Temperature range: -20 to +80°C
> Body materials; Aluminium bronze,Brass or Stainless Steel
