High Purity Air Release Valve
The High Purity Air Release Valve is designed to automatically vent trapped air or gases from high-purity fluid handling systems while preventing contamination and fluid loss. Constructed from ultra-clean materials such as PFA or PVDF, this valve ensures high chemical resistance and ultra-low particle generation. Its compact, lightweight design makes it ideal for maintaining process efficiency, preventing airlocks, and safeguarding system components in ultra-pure and corrosive environments.
Key Features of High Purity Air Release Valve
- High-Purity Materials: Manufactured from PFA or PVDF for ultra-clean, chemically inert performance.
- Automatic Air Venting: Efficiently removes air pockets to prevent flow disruption and system damage.
- Non-Contaminating Design: Internal surfaces are smooth and free from dead zones to maintain fluid integrity.
- Corrosion Resistant: Ideal for aggressive acids, solvents, and ultra-pure water applications.
- Low Maintenance: Simple and durable construction ensures long-term reliability.
- Cleanroom Manufactured: Assembled and tested in ISO Class 100 or better cleanroom conditions.
- Compact and Lightweight: Suitable for space-constrained high-purity system installations.
- Standards Compliant: Meets SEMI F57, FDA, and USP Class VI requirements for purity and safety.
