SMC KT-VBA43A-1-Advanced Pressure Amplification for Industrial Automation
2025/ 07/ 28
The SMC KT-VBA43A-1 Pneumatic Booster Valve is engineered to elevate industrial pneumatic systems by amplifying input pressure up to 2 times (select models up to 4x). Designed for localized high-pressure requirements in low-pressure overall circuits, this valve operates through a dual-chamber reciprocating piston mechanism. Input air drives a piston assembly that compresses air in the chamber, delivering stabilized high-pressure output through a self-regulating pressure control system.

Key Features:
- Dual-Stage Pressure Amplification: Achieves output pressures up to 1.6 MPa (232 psi) with input ranges of 0.2-1.6 MPa
- Precision Pressure Control: Manual adjustment via ergonomic handwheel with built-in pressure relief mechanism
- Compact Integration: Directly connects to VBAT series accumulators for space-efficient installations
- Self-Regulating Design: Automatic pressure stabilization through feedback-controlled exhaust valves
- Low Maintenance: Lubrication-free operation with wear-resistant internal components
Technical Specifications:
- Port Sizes: Rc/G 1/4" to 1/2" (NPT/NPTF optional)
- Operating Temperature: -10°C to 60°C (14°F to 140°F)
- Maximum Flow: 1,900 L/min (ANR)
- Noise Reduction: Integrated silencer with <70 dB(A) emission
Applications:
- High-pressure clamping in CNC machining centers
- Pneumatic actuators requiring localized pressure boosting
- Leak testing systems for automotive components
- Precision spray coating equipment in electronics manufacturing
Installation Notes:
Requires upstream oil mist separator (AM series) and downstream exhaust filter. Maintain minimum 50mm clearance for handwheel operation and servicing.
