pneumatic PTFE-Lined Butterfly Valve
Pneumatically actuated butterfly valve with a PTFE liner, providing broad chemical resistance and long service life in industrial service.
特点
- FEP-lined, with all fluid-wetted parts of fluoroplastic construction. It provides corrosion and wear resistance for acids, alkalis, and other media at any concentration, making it a fit for corrosive-duty service.
- The lip-type resilient seal pair extends service life.
- The PTFE seal is age-resistant, corrosion-resistant, and durable, meeting zero-leakage standards.
