Industrial High-Flow Hydraulic Filters: D & R Series with KB Bypass

Product Overview:

This specialized filter series is engineered as a premium replacement for Hydac-spec pressure line (D) and return line (R) housings, ranging from standard sizes to massive 1700R/2600R industrial specifications. In 2026, across precision metallurgical machinery, power plant lubrication systems, and large-scale power units, these elements—powered by patented ON (Betamicron®) technology—effectively intercept microscopic contaminants, ensuring fluid integrity and extending the lifespan of critical pumps and valves.

Featured Model Matrix:

• Pressure Line Series: 0660D020ON ($20\mu\text{m}$ Absolute).

• Return Line Series: 0500R020ON ($20\mu\text{m}$ Absolute).

• Large Capacity/Safety Series: 1700R020ON/-KB ($20\mu\text{m}$), 2600R010ON/-KB ($10\mu\text{m}$).

Key Technical Advantages:

• ON (Betamicron®) Grade Media: Utilizes multi-layer gradient inorganic glass fiber, delivering a beta ratio of $\beta_x(c) \ge 1000$. It captures ultrafine particles while maintaining superior flow capacity and low operating pressure drop.

• KB (Bypass Valve) Safety Feature: The /-KB suffix indicates an integrated precision bypass valve. During cold starts or severe element clogging, the bypass opens automatically to protect the core from collapsing and ensures continuous flow to prevent pump cavitation.

• Superior Dirt Holding Capacity (DHC): Large format elements like 1700R and 2600R feature optimized pleat geometry, maximizing the effective filtration area for longer service intervals during intensive 2026 operations.

• Reinforced Structural Support: Thickened galvanized anti-corrosion cores ensure structural stability under flow pulses or pressure fluctuations, preventing media fatigue failure.

• $100\%$ Physical Interchangeability: Manufactured to strict industrial tolerances with high-grade NBR seals, guaranteeing a zero-leakage fit with original housings.

Detailed Specifications:

• Filtration Ratings: $10\mu\text{m}$ (2600R) / $20\mu\text{m}$ (0500R/0660D/1700R).

• Filter Media: High-performance composite Microglass (ON).

• Collapse Rating: $20 \text{ bar}$ (Standard).

• Seal Material: Nitrile (NBR) [Viton/FKM optional].

• Integrated Features: Optional KB Bypass Valve (typically $3 \text{ bar} \sim 6 \text{ bar}$ opening pressure).
