Airtac 2JS Angle Seat Valve 2JS250-25-Q80
2. Stainless steel construction (body & linkage) ensures superior corrosion resistance. PTFE sealing components provide broad chemical compatibility, suitable for high-temperature and highly corrosive fluid handling.
3. Optimized 45° angle seat design with streamlined internal flow path minimizes pressure drop and ensures laminar flow for enhanced throughput. Integrated filter element in linkage prevents contamination ingress, extending service life.
4. Position indicator window enables visual monitoring and precise flow rate adjustment. Optional retrofit with limit switch or emergency manual override for enhanced functionality.
5. Recessed metal pneumatic ports with transition adaptor plate facilitate seamless installation of NAMUR-standard solenoid valves.
6. 360° rotatable actuator assembly simplifies orientation adjustment during installation.

Heavy-duty angle seat valve with 90° flow path design, optimized for high-temperature liquid and steam applications. Features zero-leakage PTFE bellows seal and anti-vibration stem design. The stainless steel construction ensures corrosion resistance in aggressive environments. Requires filtered compressed air (40μm, lubricated or non-lubricated) for actuator operation.
- Steam sterilization systems in pharmaceutical plants
- High-temperature water circulation in food processing
- Chemical dosing systems with corrosive media
- Industrial boiler feed water control
- Beverage filling line CIP (Clean-in-Place) systems
Installation requirements:
Install with valve stem vertical (±15° tolerance). For steam applications,
allow 15-minute warm-up period with valve partially open.
Use 20cm straight pipe upstream for optimal flow characteristics.
