The SMC KT-VBA20A-2 switch valve maintenance kit is engineered for routine service of VBA20A series booster regulators used in industrial pneumatic systems. By replacing worn internal switch valve components, this kit helps maintain stable outlet pressure, reduce leakage, and support consistent 2:1 pressure boosting in air supply lines.
Key features
-
Genuine SMC switch valve maintenance kit for VBA20A booster regulators.
-
Targets the internal switching valve section to restore smooth valve operation and responsiveness.
-
Helps correct issues such as continuous bleeding, abnormal exhaust noise, or unstable outlet pressure associated with switch valve wear.
-
Manufactured to SMC’s original specifications for fit, sealing performance, and durability in demanding pneumatic environments.
Typical applications
-
Preventive and corrective maintenance on SMC VBA20A booster regulators in factory air systems, machine tooling, and automation lines.
-
Service of low air consumption booster regulator installations where reliable pressure increase up to approximately 2:1 is required.
-
Use in maintenance programs to minimize unplanned downtime and keep downstream equipment supplied with stable elevated pressure.
Benefits for maintenance teams
-
Quick, kit-based replacement of critical switch valve parts instead of a complete regulator change-out.
-
Supports longer service life of VBA20A booster regulators and helps protect connected pneumatic components from pressure fluctuations.
-
Simplifies inventory management with a single SMC part number (KT-VBA20A-2) dedicated to the switch valve section.
Compatibility
-
Compatible model: SMC VBA20A series booster regulators (3/8 in port type such as VBA20A-03 and related variants).
-
For other service sections (cylinder, governor, seals, check valves), SMC offers companion kits KT‑VBA20A‑1, KT‑VBA20A‑3, KT‑VBA20A‑4, KT‑VBA20A‑5, and KT‑VBA20A‑6 as indicated in SMC maintenance documentation.
