VBA40A-F04GN: Power Multiplication, Precise Pressure Control! Pneumatic Booster Valve Empowers Localized High-Pressure Requirements

In automation equipment, when certain actuators (such as small clamping cylinders, brakes) require pressure higher than the main air supply pressure, configuring a separate high-pressure air compressor is costly. The VBA40A-F04GN pneumatic booster valve utilizes the differential principle of a large-area piston driving a small-area plunger to amplify standard air supply pressure, providing the necessary high-pressure air source for local workstations. It is an ideal solution for optimizing system configuration and saving energy.Core Product Advantages

• High Pressure Ratio OutputEmploys the differential principle of a large-area piston driving a small-area plunger. It can amplify standard air supply pressure (e.g., 0.5-0.7 MPa) by a fixed ratio (e.g., 2:1, 4:1) to a maximum of 1.0 MPa or higher, meeting localized high-pressure demands.
• Automatic Pressure RegulationIncorporates an internal pilot valve or pressure regulation mechanism. It automatically stops boosting when the output pressure reaches the set value, ensuring stable output pressure and preventing overshoot.
• Large Flow Capacity & Fast ResponseFeatures optimized flow path design, ensuring substantial output flow (Cv value) during pressurization and enabling rapid operation of downstream actuators.
• No External Power RequiredOperates directly using standard compressed air as the power source, eliminating the need for electricity or hydraulic oil. This ensures simple installation, safety, and energy efficiency.
• Compact and Rugged StructureThe valve body is made of metal, offering a compact structure, high pressure resistance, and suitability for industrial environments.

Typical Application Scenarios

• Localized High-Pressure Clamping:​ Generates higher clamping force in fixtures, allowing small-bore cylinders to achieve powerful clamping.
• Pneumatic Braking:​ Provides instantaneous high pressure for brakes, enabling fast and reliable braking.
• High-Pressure Blow-off:​ Delivers high-pressure airflow to specific workstations for precision cleaning or blow-off tasks.
• Tool Testing:​ Provides an adjustable high-pressure air source for pneumatic tool test benches.

Technical Parameters (Typical Values)

• Port Size: G1/4″ (F04 may indicate port code)
• Boost Ratio: 2:1 (e.g., Input 0.6 MPa, Output 1.2 MPa)
• Maximum Input Pressure: 0.8 MPa
• Maximum Output Pressure: 1.6 MPa or higher (depending on boost ratio)
• Temperature Range: -5℃ ~ +60℃

SummaryThe VBA40A-F04GN booster valve acts as a “Pressure Amplifier” for pneumatic systems. It cleverly utilizes pneumatic principles to provide the necessary high pressure for specific application points without requiring an overall increase in system pressure, achieving an optimal balance between system energy consumption and performance.Choosing the VBA40A-F04GN means opting for a smarter, more economical, and more flexible solution to meet localized high-pressure demands!
