As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents the High Pressure Cap Filter Screen – engineered to withstand up to 1000 PSI with a precision 5 micron filtration rating. Made from high-grade 316L stainless steel, this filter is designed to deliver reliable performance in demanding environments, including hydraulic systems, oil & gas applications, and chemical processing. The integrated bypass valve ensures continuous flow even during filter maintenance, minimizing downtime and protecting downstream equipment.
Our cap filter screen is built for longevity and ease of installation. The 316L material offers excellent corrosion resistance against chlorides, acids, and saline environments, making it suitable for offshore and marine applications. With a robust construction that meets international standards, this product is a cost-effective solution for high-pressure filtration needs.
Below we provide detailed technical specifications, key features, and answers to common questions. Please review the information to understand how this filter can enhance your system's efficiency.
Key Features & Benefits
- High Pressure Capacity: Rated for 1000 PSI, suitable for heavy-duty industrial circuits.
- Precision Filtration: 5 micron absolute rating removes fine particles, protecting valves and actuators.
- 316L Stainless Steel: Superior corrosion resistance and strength; ideal for harsh chemicals and high temperatures.
- Integrated Bypass Valve: Prevents system starvation if the element becomes clogged; maintains flow continuity.
- Cap Design: Easy to install and replace – no special tools required for standard configurations.
- Customizable Options: Available with different thread sizes, O-ring materials, and micron ratings upon request.
- Wide Application: Works in hydraulic power units, lubrication systems, water treatment, and food processing.
Technical Specifications
| Parameter | Value |
| Material | 316L Stainless Steel (wire mesh & support) |
| Max Operating Pressure | 1000 PSI (69 bar) |
| Filtration Rating | 5 Micron (absolute) |
| Bypass Valve | Integrated, cracking pressure ~20 PSI (adjustable optional) |
| Connection Type | Cap design with NPT/BSP threads (custom sizes available) |
| Operating Temperature | -20°F to 400°F (-29°C to 204°C) with standard seals |
| Max Flow Rate | Depends on thread size; e.g., 1/2" NPT ~ 15 GPM @ 100 PSI drop |
| Weight | Approx. 0.5 – 2.0 lbs (varies by size) |
The bypass valve is factory-set to open at approximately 20 PSI differential, ensuring that even if the filter element becomes fully clogged, the system continues to operate without damage. This feature is especially critical in high-pressure hydraulic systems where sudden pressure loss can cause downtime.
Application Advantages
- Hydraulic Systems: Removes wear debris from pumps, motors, and valves, extending component life.
- Oil & Gas: Withstands sour service environments (NACE MR0175 compliant available upon request).
- Chemical Processing: 316L resists corrosion from many acids, alkalis, and organic solvents.
- Water Treatment: Suitable for reverse osmosis pre-filtration, cooling water, and process water.
- Food & Beverage: Sanitary design optional; 316L is FDA-compliant for certain applications.
