Pneumatic PTFE-Lined Control Ball Valve
Pneumatically actuated control ball valve with full PTFE/FEP/PFA lining, ideal for highly corrosive acid and alkali media.
Inquire NowProduct Overview
The pneumatic PTFE-lined control ball valve is fully lined with FEP/PFA to protect every wetted surface. The lining provides exceptional resistance to strong acids (HCl, H₂SO₄, HNO₃), alkalis, oxidizers, and organic solvents that would otherwise attack standard stainless steel trim.
Combined with V-port trim and a diaphragm actuator, the valve delivers proportional flow control across wide rangeability, the preferred choice for chemical, pharmaceutical, and high-purity applications.
Key Features
- Full Lining: FEP/PFA lining on body, ball, and stem flange for total chemical isolation
- V-Port Throttling: Equal-percentage flow characteristic with high rangeability
- Pneumatic Smart Drive: Diaphragm actuator with smart 4-20 mA positioner
- Leak-Proof Stem: Live-loaded packing plus bellows seal option for toxic media
- FDA Compliance: FEP/PFA lining meets FDA 21 CFR for food and pharma
Technical Highlights
Typical Applications
Strong acid/alkali transport, chlor-alkali production, pharmaceutical intermediates, semiconductor wet benches, food-grade chemicals.
