The SMC KT-VBA43A-1 is a high-performance booster regulator designed to amplify pneumatic system pressure efficiently. Part of SMC's renowned VBA series, this device enhances operational efficiency by doubling the main line pressure, making it ideal for applications requiring elevated pressure outputs. Below is a comprehensive English description of its features, specifications, and applications:

Key Features

• Pressure Amplification: The KT-VBA43A-1 increases the inlet pressure (up to 0.8 MPa) to a higher outlet pressure (up to 1.6 MPa), achieving a pressure ratio of 2:1. This reduces energy consumption by minimizing the need for external power sources.
• Compact and Lightweight: Weighing 289 grams (0.635 lbs), its compact design allows easy integration into space-constrained systems.
• Low Pulsation: Engineered to minimize pressure fluctuations, ensuring stable output for precision applications.
• Durable Construction: Built with high-quality materials to withstand demanding industrial environments, including resistance to wear and corrosion.
• Maintenance-Friendly: Comes with a dedicated maintenance kit (KT-VBA43A-1), containing replacement seals, springs, and lubricants for quick servicing.

Technical Specifications

• Inlet/Outlet Port Size: 1/2 inch (both ports).
• Maximum Operating Pressure: 1.6 MPa (232 psi).
• Pressure Ratio: 2:1 (adjustable via handle operation).
• Flow Capacity: Up to 30 L/min (ANR) at 0.7 MPa inlet pressure.
• Operating Temperature: -10°C to 60°C (14°F to 140°F).
• Recommended Lubrication: Turbine oil ISO VG32.

Functional Description

The KT-VBA43A-1 operates via a pilot-operated mechanism. When inlet pressure is applied, the internal piston and valve assembly modulate the output pressure to maintain the desired ratio. A built-in pressure gauge (optional) allows real-time monitoring, while adjustable settings enable customization for specific applications.

Applications

• Automation Systems: Enhances pressure for actuators, clamps, and grippers in robotic assembly lines.
• Packaging Machinery: Powers high-speed sealing and cutting processes.
• Food and Beverage: Provides reliable pressure for filling and capping machines.
• Printing Industry: Ensures consistent inkjet or label application pressure.
• Semiconductor Manufacturing: Delivers precise pressure control for delicate wafer processing.

Maintenance Guidelines

Regular inspection of seals, springs, and lubrication is critical. The maintenance kit includes:

• Piston seals (2 pcs)
• Rod seals (1 pc)
• O-rings (4 pcs)
• Grease package (10g)
  Follow SMC’s step-by-step disassembly/reassembly procedure to ensure longevity and optimal performance.

Safety Considerations

• Always depressurize the system before maintenance.
• Use only SMC-approved replacement parts.
• Avoid exposure to corrosive gases or liquids.

The SMC KT-VBA43A-1 is a versatile, energy-efficient solution for industrial pressure amplification, offering reliability and ease of maintenance in diverse pneumatic applications.
