Dome loaded regulators and back pressure maintaining valves Spring loaded regulators and Back pressure maintaining valves 8 ENERGY Pressure control solutions 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. > Manual adjustment via knob > Port sizes: 1/4" to 1" > Pressure range: 100 to 420 bar > Flow rate: up to 1000 Nm 3 /h > Temperature range: -20 to +80°C > Body materials: aluminium bronze, brass or stainless steel 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. > 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 Nm 3 /h > Temperature range: -20 to +80°C > Body materials: aluminium bronze, brass or stainless steel
