Dome Pressure Regulator with Pilot D2

Dome pressure regulators are characterised by accurate regulation and a large throughput.

The dome pressure regulator works according to the principle of the pressure balance between dome pressure and outlet pressure.

A large independence from fluctuation of the inlet pressure is reached with a balanced poppet. 

If the dome pressure regulator is used for the pressure control of gases, the dome pressure can controlled by needle valves.

For the pressure regulation of liquids and aggressive gases, the dome can be filled externally with compressed air or nitrogen by means of a pilot pressure regulator.

Body: brass or stainless steel
Seat: EPDM or viton
Diaphragm: EPDM or viton
Max. inlet pressure: 100 bar
Outlet pressure ranges: 0.2-5, 1-100 bar
Operating temp.: -20°C to +60°C
Gas: in- / outlet: G 2". gauge: G 1/4".

The dome pressure regulator is used as a line pressure regulator. Without exchanging parts it is suitable for a large outlet pressure range.

Independent of the used material the pressure regulator is applicable for different gases and liquids.

Urgently recommend the connection of a fine filter with max. 40 μ at the inlet of the pressure regulator, to protect following components with suitable relief valves against inadmissibly high pressures.

To identify the correct order code for your Pilot D2

Start with the model number (in this case 37P), then add the appropriate number options from columns A, B, C, D, E & F in the table below followed by the gas to be used.

37P-1-0-1-0-0-0-Argon specifies a Pilot D2 model in brass with 100 bar pressure, Ø 12.7 seat, EPDM diaphragm, no gauges & G 1" female part inlet/outlet, for use with Argon gas.
