VBA10A-02GN: SMC Pressure Booster Valve, the High-Pressure Conversion Expert for Industrial Pneumatic Systems

The VBA10A-02GN is a pressure booster valve produced by Japan’s SMC Corporation, belonging to the VBA series. This booster valve utilizes a pneumatic operation principle, capable of boosting factory air line pressure up to 2 times without requiring an electrical power supply. It features a compact structure, easy installation, and convenient maintenance. It is widely used in industrial automation control systems to provide high-pressure air supply support for equipment.

Core Product Advantages

1. No Electrical Power Required Employs a pneumatic boosting principle. It only requires connection to a factory air line to achieve pressure boosting, eliminating the need for an additional electrical power supply. This saves energy, is environmentally friendly, and is suitable for explosion-proof environments.
2. 2:1 Boosting Ratio Can boost the input pressure up to a maximum of 2 times. With an input pressure range of 0.1~1.0 MPa, the output pressure can reach 0.2~2.0 MPa, meeting high-pressure air supply requirements.
3. Compact and Space-Saving Structure The booster valve can be directly connected to an air tank, saving installation space. Particularly suitable for automated equipment with space constraints.
4. Easy Maintenance Features a manually operated design, allowing for convenient pressure adjustment and simple routine maintenance, thereby reducing operating costs.

Working Principle

The VBA10A-02GN employs a dual-piston boosting structure. The input air pressure splits into two paths. One path opens the check valves to fill booster chambers A and B. The other path passes through the regulator valve and the directional control valve to fill drive chamber B, while drive chamber A exhausts. This causes the large piston to move left, driving the small piston also to move left, thereby pressurizing booster chamber B. The high-pressure air opens the check valve and is delivered from the outlet. When the piston reaches the end of its stroke, the directional control valve switches, causing drive chamber A to receive air and drive chamber B to exhaust. The piston then moves in the reverse direction, pressurizing booster chamber A, and continues to deliver high-pressure air from the outlet. By repeating these actions continuously, a steady stream of high-pressure air is obtained at the outlet. The outlet pressure is fed back to the regulator valve, allowing the outlet pressure to be automatically maintained at the set value.

Typical Application Scenarios

1. Industrial Automation Production Lines Used in automated production lines such as automotive manufacturing and electronic device production to provide a high-pressure air supply for pneumatic actuators, enabling workpiece clamping, positioning, and handling, thereby improving production efficiency and product quality.
2. Pressure Testing Equipment Used in leak testing, pressure testing, and other equipment to provide a stable high-pressure air source, ensuring the accuracy and reliability of the testing process.
3. Spraying Equipment Used in spraying equipment to control spraying pressure and flow rate, ensuring uniform coating application and improving product quality.
4. Pneumatic Tools Provides a high-pressure air supply for pneumatic tools, enhancing their working efficiency and power output.

Installation and Usage Precautions

1. Installation Requirements The booster valve should be installed level, and the mounting nuts must be securely fastened. If vibration is present, install anti-vibration rubber pads. Before connecting piping, thoroughly blow-clean the pipes to ensure no contaminants enter.
2. Pressure Setting In the factory default state, air will vent (overflow) upon supply. Quickly turn the adjustment dial outward (counter-clockwise as indicated by the arrow). After setting the pressure, push the dial back in. To reduce pressure on the secondary (output) side after setting, the dial can be turned further out (-). For re-setting, first reduce the pressure below the desired new set point before proceeding.
3. Safety Protection When the booster valve outlet pressure exceeds 1.0 MPa, verify the pressure ratings of pipe fittings, air lines, valves, etc., in the system. Install an air filter and oil mist separator on the secondary (output) side to prevent dust from entering downstream equipment.
4. Regular Maintenance It is recommended to drain condensate daily. Regularly check the operational performance of the booster valve to ensure long-term stable operation. If the valve remains in the set state for extended periods, it is normal for the venting time from the exhaust port to become longer when the valve switches.
5. Handling Requirements Hold the booster valve at both ends during handling. Do not grip the central black protruding dial. When carrying, always use both hands to hold the ends. Never hold by the dial, as its detachment could cause damage to the main body.
