Instantaneous maximum air flow

Necessity of confirming the gas tank when selecting the booster valve

The boost valve is selected based on the average air flow rate Q AVE.
The necessity of the air tank is confirmed based on the instantaneous maximum air flow rate Q MAX.

Check the outlet air flow rate at the intersection of the booster valve inlet pressure (P1) and the cylinder required supply pressure (P3) in the sample flow characteristic table (P.4). If it is greater than or equal to the average air flow rate Q AVE, it can be used.
If the outlet air flow rate is less than the instantaneous maximum air flow rate Q MAX, an air tank is required.
If the outlet air flow rate is greater than or equal to the instantaneous maximum air flow rate Q MAX, an air tank is not required.

Notice

• The booster valve is an air-powered compressor, so it consumes air.The air consumption is about 0.72 times the amount used on the outlet side. Therefore, the required inlet supply is about 1.72 times the amount used on the outlet side.

Selected Examples

Results
The outlet air flow rate of VBA10A is greater than or equal to the average air flow rate Q AVE, but less than the instantaneous maximum air flow rate Q MAX, so it can be used, but a gas tank is required.
The outlet air flow rate of VBA20A is greater than or equal to the average air flow rate Q AVE and the instantaneous air flow rate Q MAX, so it can be used without a gas tank.

Working principle

Current Products

Gas-saving booster valve

The existing product has 2 pistons and 4 chambers.
The inlet pressure enters the 2 chambers, pushing the piston in the direction of the ① arrow, and the outlet outputs high-pressure air.
At the same time, the air pushing the piston in the ② part is completely exhausted.

The number of pistons in the air-saving booster valve has increased to 3, and the number of chambers has increased to 6.
The inlet pressure enters the 2 chambers, pushing the piston in the direction of the ① arrow, and at the same time, the air pushing the piston in the ② part in the previous process is introduced into the next chamber through the exhaust return air path, pushing the piston in the direction of the ③ arrow.
The reused air is exhausted in the next process.
Therefore, compared with the previous product in which all the air is exhausted after the piston is pushed, the air-saving booster valve reuses the air after the piston is pushed to drive the piston, achieving a 40% reduction in exhaust volume.

Example of using the circuit

• In the case where only part of the factory equipment requires high pressure, by installing a booster valve in the corresponding local gas circuit, it is possible to use high-pressure equipment locally while keeping the overall gas circuit at low pressure.

※When using two booster valves for two-stage boosting, please supply sufficient flow to each booster valve to ensure the stability of the booster valve inlet pressure.

• During the process of filling the gas tank, a circuit with a booster valve and a check valve in parallel is used. When the pressure of the gas tank is lower than the gas source pressure at the inlet, the gas tank is filled with gas through the check valve, thereby shortening the filling time.

The inlet pressure (P1) first inflates P2 through the one-way valve until P1 = P2.

• The output force of the actuator is insufficient, and a cylinder with a larger cylinder diameter cannot be used due to space limitations. In this case, a booster valve can be used to increase the output force without replacing the actuator.

• The drive components need to be miniaturized, requiring the cylinder to be small in size, but the predetermined output force is required to be large. In this case, a booster valve can be used.

• When the cylinder is in one-way motion, a boost valve is installed in the corresponding intake circuit to reduce the consumption of compressed air.

Design Considerations

warn

①Abnormal outlet pressure warning

• If the outlet pressure drops due to unexpected circumstances such as mechanical failure, and a major accident is predicted, please take safety measures on the system side.
• If the inlet pressure fluctuates greatly, the outlet pressure may exceed the set range and cause an accident, so be sure to take safety measures to deal with pressure abnormalities.
• Please use within the outlet pressure range.

②Residual pressure treatment

• When the residual pressure on the outlet side needs to be quickly released due to maintenance, etc., please connect a 3-way valve to the OUT side of the booster valve (see the figure below). If you only connect to the IN side to release the residual pressure, the outlet pressure will not be eliminated due to the action of the check valve in the booster valve, so please be careful.

• After work is completed, cut off the supply pressure on the inlet side. Stop the booster valve to prevent unnecessary air consumption.

• Please ensure that the air supply capacity is not less than the minimum operating pressure (0.2MPa). If the internal operating pressure is below the minimum operating pressure, the switching valve may not operate.
• There are sliding parts inside the booster valve, which will generate dust. If necessary, install a cleaning device such as an air filter or oil mist separator on the outlet side.
• Please connect the oil mist collector to the outlet side. If oil is retained in the booster valve, it may cause malfunction.
• Please pay attention to the operating pressure range and pressure resistance of peripheral components

②Ensure maintenance space

• Please ensure the space required for maintenance.

③Counting the number of moves

• When using a magnetic switch to count the number of operations, use a component with a counting speed of at least 1kHz.

Select

Notice

①Specification confirmation

• Please consider the usage conditions and use within the specifications of this article.

②Select

• When selecting the size of the booster valve, please confirm it based on the conditions required on the outlet side of the booster valve (pressure, flow rate, production cycle, etc.), and follow the selection order and selection procedure shown in this article.
• The booster valve is an air-powered compressor, so it consumes air. The air consumption is about 0.72 times the amount used on the outlet side. Therefore, the required supply on the inlet side is about 1.72 times the amount used on the outlet side.
• When operating continuously for a long time, please be careful to confirm the life of the booster valve.
• The life of the booster valve is not determined by the usage time, but by the number of operations (piston sliding distance). The number of operations (piston sliding distance) is determined by the air flow rate on the outlet side of the booster valve. The larger the air flow rate on the outlet side of the booster valve, the shorter the life. By increasing the size of the booster valve, the frequency of operation is reduced, so the usage time can be extended.
• When using two boosters for two-stage boosting, please install a pressure vessel such as an air tank between the boosters to ensure stable pressure supply to the downstream booster valve.

Install

Notice

①Handling

• When carrying, hold both ends of the length with both hands.

②Install

• When installing, please note that the vibration of the piston will be transmitted, so please tighten the mounting bolts according to the table below.

• If you want to reduce the degree of vibration transmission, please use anti-vibration rubber pads.
• When installing the pressure gauge, please tighten it according to the tightening torque of 7 to 9 N·m.

Piping

Notice

①rinse

• Please flush the pipes thoroughly before piping to remove cutting chips, cutting oil, dust, etc. If these impurities enter the booster valve, it will cause unexpected malfunction and reduce durability.

②Pipe size

• In order to perform the intended function of the booster valve, please select piping that matches the port size.

Gas source

Notice

①Quality of air source

• Please install an air filter on the upstream side of the booster valve. Please select a product with a filtration accuracy of 5μm or more.
• If dry air (atmospheric pressure dew point - below 23°C) is used, the volatilization of the internal grease may be accelerated, shortening the service life.

②Pressure fluctuations

• Please keep the inlet pressure stable.

③Please take measures such as installing an aftercooler, air dryer, condensate collector, etc.

• Compressed air containing a large amount of condensed water may cause malfunction of pneumatic components. Please take measures such as installing an aftercooler, air dryer, condensed water collector, etc.

Notice

①Condensate drainage

• If the machine is used with a large amount of condensed water remaining in the filter or tank, the condensed water will flow out and cause malfunction, so the condensed water must be drained once a day. Even if it is equipped with an automatic drain, it must be checked to ensure that it is drained once a day.

②maintain

About Booster Valve

• The service life will vary depending on the quality of the air used and the conditions of use. As a sign that the service life is about to end, the following phenomena will occur. Even if the air is not consumed on the outlet side, the exhaust sound of the booster valve can be heard every 10 to 20 seconds. If the above phenomenon occurs, please perform maintenance as soon as possible.
• Please have personnel with rich knowledge and experience in pneumatic components perform maintenance in accordance with the maintenance instructions.

About Muffler

• Discoloration and deterioration may occur due to turbine oil, grease, condensed water contained in the exhaust gas, the usage environment, etc. This is not abnormal if regular maintenance is performed, so please be sure to perform regular maintenance.

③Usage Environment

• Depending on the operating environment, the muffler may emit white mist and condensation may form around the switch valve and muffler. However, product performance will not be affected because the condensation occurs on the outside of the boost valve.
