Polyval Cartridges

Summary

Product Identification

Polyval® and Polyval® HE pleated polypropylene cartridges offer an economic alternative for initial fine filtration stages. They are designed to filter water or fluids from the point of entry to the point of use, including secondary circuit systems in industrial processes.

• Polyval®: Continuous length construction with 90% filtration efficiency.
• Polyval® HE: 10'' module construction with 98% filtration efficiency.
• Filtration Thresholds: From 0.2 µm to 40 µm.
• High surface retention capacity.
• Excellent chemical compatibility.
• Resistance to bacterial aggression.
• No fiber release.
• Available end cap types: DOE, 3S, 3F, 7S, 7F.

Operating Limits

Applications

• Filtration of well water or tap water.
• Filtration of process water to protect sensitive systems and equipment.
• Boiler feed water filtration.
• Recycled water filtration.
• Chemical filtration.

Precautions for Use

• Performance is dependent on proper system sizing.
• Certain applications may require water treatment systems to comply with specific standards or certifications.
• These cartridges should not be used with microbiologically unsafe water or fluid.
• Polyval cartridges are not classified as medical devices.
