4. Performance Features
-
High-Pressure Capability (PN250)
– Forged steel body ensures structural integrity under extreme pressures up to 25 MPa. -
Floating Ball Design
– Ball presses against downstream seat under pressure, providing tight sealing. -
Threaded End Connections (Nipples)
– Easy installation in high-pressure piping systems without welding; suitable for compact layouts. -
Electric Motorized Actuation
– Enables remote automated operation; available with fail-in-place or fail-last functionality. -
Versatile Seating Options
– PTFE for standard service (bubble-tight shut-off)
– PEEK or metal seat for high-temperature or abrasive applications -
Compact & Robust
– Small footprint suitable for skid-mounted systems and high-pressure hydraulic circuits.
5. Applications
-
Hydraulic power units (HPU)
-
High-pressure water jetting systems
-
Oil & gas test benches
-
Chemical injection skids
-
Industrial high-pressure process lines

Notes:
-
The term “Nipples” indicates threaded end connections (male threads) for direct coupling into piping systems.
-
Actuator sizing is critical for PN250 applications due to high operating torque; final selection depends on actual operating pressure and media.
-
For high-temperature service (>150°C), PEEK seats or metal seats are recommended.
-
Final dimensions and specifications are subject to approved engineering drawings and project requirements.
