Proven solutions for high pressure gas
control on the outlet from the compressor
and in downstream pressure reduction
applications such as in the dispenser
Spring loaded regulators
Pressure regulators (reducers or controllers) control the
outlet pressure over a range of varying inlet pressures and
flows. Regulators are sometimes called 'Forward Regulators'
to prevent confusion with Back Pressure Maintaining Valves.

Dome loaded regulators
Functioning in the same way as the spring loaded pressure
regulator, but rather than using a manually adjusted spring,
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.

proportional valve
