Assuming an intake pressure of 0.5MPA and a required boost to 0.8MPA, with an average air flow rate of 500L/Min, based on the boost ratio and pre selected flow rate of VBA20A, comparing the flow characteristics of 20A, the intake P1=0.5MPA. When the air consumption is equal to 500L/MIN, the intake pressure is around 0.85MPA, which is higher than the predetermined 0.8MPA and meets the design requirements. Therefore, the VBA20A model is selected for use
Assuming that the intake pressure is 0.5MPA, it is required to increase the pressure to 0.8MPA, and the average air flow rate is 50OL/Min. The outlet pressure should not fluctuate
Based on the selection results of Example 1, the VBA20A model was chosen because the booster valve is based on the piston type boosting principle, and the outlet pressure will have periodic pulsation. Therefore, a small air storage tank was selected to filter the pulsation. Since there are no special requirements, the air storage tank can be selected based on the on-site situation. Now, a 10L air storage tank is selected as the matching tank
Other selection cases
If the booster valve is used for periodic gas consumption, or if there are requirements for inflation time when inflating sealed containers, you can contact customer service for assistance in selection reference
The function of gas cylinders
Relieve pressure fluctuations at the outlet of the pressure boosting valve
In situations where intermittent movements cause air consumption to exceed supply capacity, concentration can be used
The amount of air consumed is stored in a gas tank for use. If it is caused by continuous actions
If the air consumption exceeds the supply capacity, using gas cylinders will not be effective.
Precautions for using gas cylinders
one
An oil mist separator needs to be installed on the side near the booster valve. If the quality of compressed air is not guaranteed, it will result in poor operation of the booster valve (unable to boost) and reduced durability.
two
In situations where dry air is used (atmospheric dew point below 17C), the lifespan may be shortened due to the evaporation of internal lubrication.
three
The supply on the inlet side is approximately 2 times (boost ratio 2) or 4 times (boost ratio 4) the usage on the outlet side, as the boost valve is powered by air pressure. Therefore, the supply on the inlet side should be the sum of the flow rate on the outlet side and a portion of the discharge from the E port.
four
The setting of export pressure should be more than 0.1MPA higher than the inlet pressure. If the pressure difference is below 0.1MPA, it will cause unstable movement and poor movement.

Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible .
Q:Can you provide original famous pneumatic and hydraulic,instruments brand goods ?
A: Yes,We can supply like Festo,Smc,Ckd,Burket,Hydac,Rexroth,SMS,RSMT,Marsh ,Endress+Hauser etc.
Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
| Focus Point | High Temperature Environment Countermeasures | Extreme Cold Environment Countermeasures |
| Seals | Fluororubber, PTFE | Low-temperature nitrile, silicone rubber, polyurethane |
| Lubrication | High-temperature synthetic grease (low volatility) | Low-temperature grease (low pour point, low viscosity) |
| Air Supply Treatment | Strengthen cooling, efficient water removal | Ultra-low dew point drying (refrigeration + adsorption type), heat tracing |
| Metal Components | Reserve expansion clearance | Select materials with low-temperature toughness, prevent leakage due to cold shrinkage |
| Control Components | High heat-resistant grade coils, heat dissipation, low power consumption | Install insulation boxes, local heating, prevent cold condensation |
| Installation | Keep away from heat sources, add heat insulation plates | Avoid exposure to wind and snow, wrap with thermal insulation materials |
