Product descriptionWEH® pneumatic needle valves with pneumatic actuation are used where manual operation is not desired. They are suitable for integration into automated systems and are designed for medium-pressure applications.
Features- Angled version available (with replaceable valve seat)
- Valve needles and sealing seats subject to high wear available as spare parts and easily replaceable
- Anodized aluminum housing: corrosion- and wear-resistant
- Durable pneumatic actuator, tested for 100,000 cycles at 6.9 bar supply pressure
- Standard V-tip for fast opening and closing
- Metal sealing seat for high tightness requirements
- Needle valve for pneumatic shut-off and opening of high-pressure lines
NoteFor flow regulation, manually operated needle valves with regulating tips are recommended; the pneumatic needle valves are standardly equipped with a V-tip for fast opening/closing.
