High Purity Flanged Diaphragm Valve
The High Purity Flanged Diaphragm Valve is engineered for precise flow control and contamination-free operation in ultra-clean and corrosive fluid systems. It features a high-purity PFA, PTFE, or PVDF construction and a flanged end connection, ensuring chemical resistance, reliable sealing, and easy installation. The diaphragm design isolates the process media from moving parts, eliminating dead space and reducing the risk of contamination—ideal for demanding high-purity applications.
Key Features of High Purity Flanged Diaphragm Valve
- High-Purity Construction: Wetted parts made from PFA, PTFE, or PVDF for ultra-clean fluid contact.
- Flanged Connections: Secure ANSI or DIN flanged ends for stable, leak-proof installation.
- Zero Dead Space Design: Prevents fluid entrapment and promotes clean, laminar flow.
- Diaphragm Sealing: Complete isolation of fluid from the valve body and actuation mechanism.
- Corrosion & Chemical Resistance: Handles aggressive chemicals, acids, and ultra-pure fluids.
- Manual or Automated Options: Available with manual handwheel or pneumatic/electric actuators.
- Cleanroom Manufactured: Assembled in ISO Class 100 or better environments.
- Compliance Ready: Meets SEMI F57, FDA, and USP Class VI purity standards.
