pneumatic PTFE-Lined Butterfly Valve
Pneumatic PTFE-lined butterfly valve is a compressed air actuated valve with PTFE lining, offering excellent chemical resistance and durability for various industrial applications.
特点
- FEP-lined, with all wetted parts in contact with liquid made of fluoroplastic. It features excellent corrosion and wear resistance, suitable for acids, alkalis and other media at any concentration, making it an ideal choice for corrosion-resistant equipment.
- The unique lip-type elastic sealing pair design effectively extends service life.
- PTFE sealing material is aging-resistant, corrosion-resistant and durable, achieving zero leakage.
