Engineering Advantages
- Precision Throttling: Butterfly disc geometry enables smooth, proportional conductance control across the full operating range, minimizing pressure overshoot in sensitive process chambers.
- Ultra-Low Outgassing: Electropolished internal surfaces and clean-room assembly ensure minimal contamination contribution to process gas purity.
- High Cycle Durability: Pneumatic actuation with hardened pivot bearings supports >1 million maintenance-free cycles, reducing total cost of ownership in high-throughput fabs.
- Compact Footprint: Slim-profile butterfly design integrates directly into tight vacuum manifold assemblies without additional adapters.
- Drop-In OEM Replacement: Dimensional and functional equivalence to original VAT specification ensures zero re-engineering for retrofit installations.
System Architecture & Signal Flow
The 61246-PAGI-0001/0103 operates within a closed-loop vacuum pressure control architecture:
- Process Chamber → pressure sensor feedback signal
- Pressure Controller / PLC → generates pneumatic pilot command
- PAGI Pneumatic Actuator → rotates butterfly disc to target angle
- Butterfly Disc → modulates conductance between chamber and pump
- Vacuum Pump → maintains base pressure setpoint
This architecture delivers closed-loop pressure stability typically within ±0.5% of setpoint under steady-state conditions.

Technical FAQ
Q: Is this an OEM new or refurbished part?
A: Stock condition is specified at time of inquiry. Both new surplus and inspected used units may be available. Please confirm with our team before ordering.
Q: Can this valve be used with corrosive process gases?
A: The standard PAGI configuration uses aluminum body with elastomer seals. For corrosive gas compatibility (e.g., Cl₂, HF), please specify — alternative seal materials or stainless body variants may be required.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock items are sourced within 2–6 weeks depending on global availability.
Q: Do you provide a warranty?
A: Yes. All parts carry a 90-day functional warranty against defects in materials and workmanship under normal operating conditions.
Q: Can I get a datasheet or dimensional drawing?
A: Yes. Contact support@konmask.com with your part number and we will provide available VAT technical documentation.
