SMC VBA40A-F04 1/2 Manual Air Pressure Booster Regulator
Product DescriptionThe specialty regulator series VBA is a booster
regulator that saves money and energy by increasing the main line
pressure up to two times. The booster regulator, when connected to
air supply line, increases pressure up to two times and the main
air supply pressure may be set low. Desired pressure increase can
be easily adjusted.Product Feature1. Easy adjustment of output
pressure.2. Boosts local line pressure without requiring additional
power.3. Possible to get a maximum of double pressure by connecting
air with a factory line. (VBA11A: maximum 4 times)4. Space-saving
type that directly connects air tanks and booster
regulators. Product Specification

capacity of the minimum operating pressure (0.1 MPa) or
more. *2) If the OUT pressure is higher than the set pressure
by the knob, excess pressure is exhausted from the back of the
knob. *3) Flow rate at IN= OUT= 0.5 MPa. The pressure varies
depending on the operating conditions. Refer to "Flow Rate
Characteristics" .*4) Set the pressure increase ratio to 2 or
more. *5) The tank connection port cannot be used for
applications other than the connection with VBAT.

Main Dimensions Solid line: Operating
range
Operate so that the flow rate follows the solid line
even when the outlet side air has been consumed.
Ex.)
For the VBA10A: When the inlet pressure is 0.5 MPa and the set
pressure is 1.0 MPa, operate at an outlet air flflow rate of
180 L/min (ANR) or less. Dotted line: Outside of the set
pressure range P1: Inlet pressure
P2: Outlet pressure* When operated at a flow rate that
falls within the unstable area (P2 < P1 conditions) as shown in
the graphs above, the booster regulator may not operate
normally and may therefore fail to increase the pressure. Tank
Pressure PulsationPulsation is decreased with a tank. If the outlet
capacity is undersized, pulsation may
occur. Conditions Inlet pressure: 0.5 MPa Outlet set
pressure: 1 MPa Flow rate: Between 0 and max. flow
rate Performance of air tank 1. Alleviates the
pulsation generated on the outlet side. 2. When
air consumption exceeds air supply during intermittent
operation, required air will be accumulated in the tank for u
