HEAVY-DUTY DUAL STAGE REGULATOR (DSR)
The heavy-duty dual stage regulator vaporizes liquid propane to gaseous form and also regulates the
fuel pressure to meet the fuel pressure requirement.
Figure 4: Heavy Duty Dual Stage Regulator
The HD DSR is a two stage fully mechanical regulator that is available in LPG configurations. The DSR is
normally open with a positive outlet pressure and must be used with fuel lock-off upstream to prevent
fuel flow when the engine is not cranking or running. The HD DSR is connected to the DEPR, by a low
pressure flexible hose. It also has a reference port that is connected to the fuel / air mixer for turbo-
charged applications.
Key features of the HD Dual Stage Regulator are:
-
Full mechanical pressure regulation
-
Can be engine or chassis mounted (vibration requirements are defined on the installation drawing)
-
Flows 250 kW at the rate inlet pressure
-
1725 kPa inlet regulated down to a 3.5 kPa outlet pressure
