Needle valve C1-191913

pneumaticregulatingactuator

Description
WEH® pneumatic needle valves with pneumatic actuation are used where manual operation is undesirable for safety reasons and where integration into automated systems is required. The pneumatic needle valves for medium pressure are designed for long service life and easy maintenance:

• The high-stress valve needles and seats are available as spare parts and are easy to replace in a few steps.
• The anodized aluminium actuator housing is corrosion- and wear-resistant.
• The durable pneumatic actuator has been tested for 100,000 cycles at 6.9 bar compressed air.

Standard WEH® pneumatic needle valves are equipped with a V-tip for rapid opening and closing. For flow regulation, hand-operated needle valves with regulating tips are recommended.
