Product Identification

  • Model: KT-VBA43A-1
  • Series: SMC VBA Series (Booster Regulator)
  • Type: Pneumatic Pressure Amplification Valve
  • Function: Increases input air pressure up to 2 times its original value, suitable for localized high-pressure air demands in industrial systems.

Functional Features

Dual-Piston Mechanism:

  • Large Piston: Drives the amplification cycle via air pressure.
  • Small Piston: Compresses air in the boost chamber to achieve high-pressure output.

Pressure Regulation:

  • Manual Adjustment: Rotary handle with pressure scale (0–2.0 MPa).
  • Feedback Control: Maintains stable output pressure via a built-in pressure sensor.
  • Check Valves: Two integrated check valves ensure unidirectional airflow, preventing backflow.
  • Exhaust Port: Equipped with a silencer mount to reduce noise during piston reversal.
