Installation

Figures 2 and 3 show typical installations for the VBL

volume booster on piston and diaphragm actuators. A

single regulator that supplies both the positioner and

booster (or boosters) is recommended. The supply

medium must be clean, dry, oil-free air or

non-corrosive gas.

Keep in mind that many actuators require larger casing

or cylinder connections to take full advantage of the

booster's ability to deliver its high-volume output.

Dimensions are shown in figure 4. Ensure that the

supply pressure is connected to correspond with the

flow arrow on the booster.

Verify that the capacity of the regulator meets the

stroking capacity requirements.
