High Purity Foot Valve
The High Purity Foot Valve is a self-acting check valve installed at the inlet of suction lines in ultra-clean and chemically aggressive fluid systems. Constructed from high-purity materials such as PFA, PVDF, or PTFE, it combines the functions of a strainer and a non-return valve. It allows fluid to flow into the system while preventing backflow and the entry of debris. Ideal for protecting pumps and maintaining priming in high-purity applications.
Key Features of High Purity Foot Valve
- High-Purity Construction: Made from chemically inert PFA, PVDF, or PTFE for ultra-clean operation.
- Integrated Strainer Design: Prevents entry of particulates into suction lines and pump systems.
- One-Way Flow Control: Maintains pump priming by allowing only forward flow and blocking reverse flow.
- Excellent Chemical Resistance: Compatible with aggressive acids, solvents, and ultra-pure fluids.
- Cleanroom Manufactured: Produced and assembled in ISO Class 100 or better environments.
- Low Crack Pressure: Opens easily at low pressure for efficient fluid intake.
- Durable and Corrosion-Resistant: Withstands harsh environments and continuous operation.
- Standards Compliant: Conforms to SEMI F57, FDA, and USP Class VI purity requirements.
