Performance Characteristics

The PLF.BH-H160×10P incorporates several design features that collectively deliver superior filtration performance 

and operational convenience:

(1) Compact and Space-Saving Design

Compared to conventional filters with equivalent flow capacity, the PLF.BH-H160×10P features a remarkably compact structure with reduced overall dimensions. This space-efficient design is particularly advantageous in modern hydraulic power units and machinery where installation space is at a premium. The smaller footprint allows for more flexible system layouts and simplifies integration into existing equipment without extensive modification.

(2) Wide Operating Pressure Range

The filter is engineered to perform reliably across a broad spectrum of operating pressures, making it suitable for diverse

 hydraulic applications. Whether installed in low-pressure return lines or high-pressure supply circuits, 

the PLF.BH-H160×10P maintains consistent filtration efficiency without compromise. This versatility reduces inventory

 requirements, as a single filter model can serve multiple pressure applications.

(3) Flexible Filter Element Replacement

User convenience is central to the filter's design philosophy. The PLF.BH-H160×10P offers two distinct methods for

 filter element replacement, accommodating varying installation configurations and maintenance preferences:

· Top Access Method: Operators can open the upper cover and replace the filter element directly from above,

 which is ideal for installations with ample overhead clearance.

· Bottom Access Method: Alternatively, the housing can be unscrewed (after relieving system pressure and draining oil) to

 remove and replace the element from below. This option is valuable when vertical clearance is restricted.

This dual-access flexibility ensures that maintenance can be performed efficiently regardless of the filter's installation

 orientation or surrounding equipment constraints.

(4) Reversible Flow Direction

The PLF.BH-H160×10P offers exceptional installation flexibility through its reversible flow capability. Should the standard

 flow direction prove difficult to accommodate within a specific system layout, operators can simply remove the four screws 

on the cover, rotate the cover assembly 180 degrees, and reattach. This simple adjustment reverses the medium flow

 direction through the filter, allowing the unit to be installed in virtually any pipeline configuration without requiring 

custom modifications.

(5) Dual-Protection Safety Features

The filter is equipped with both a bypass valve and a differential pressure signaling device, providing comprehensive system

 protection:

· Bypass Valve: In the event that the filter element becomes severely clogged and is not replaced promptly, the bypass 

valve opens to allow oil flow to continue, preventing pump cavitation, system starvation, or catastrophic pressure buildup. 

This safety feature ensures that the hydraulic system remains operational even during maintenance oversights, albeit with

 reduced filtration protection.

· Differential Pressure Signaling Device: A built-in transmitter continuously monitors the pressure differential across the filter

 element. As contaminants accumulate on the element surface, the differential pressure gradually increases. When the

 pressure reaches the preset alarm threshold, the signaling device sends a visual or electrical warning message to the

 control system or operator, indicating that the filter element requires immediate replacement. This proactive monitoring

 prevents the filter from operating in bypass mode unnecessarily and ensures consistent fluid cleanliness.

High-Performance Glass Fiber Media

The PLF.BH-H160×10P utilizes high-quality glass fiber filtration media, which offers several compelling advantages over 

conventional materials:

· High Filtration Efficiency: The glass fiber matrix provides precise particle capture at the rated 10 μm accuracy, ensuring

 removal of contaminants that cause abrasive wear in sensitive hydraulic components.

· Excellent Dirt-Holding Capacity: The depth-loading structure of glass fiber media allows for substantial contaminant storage, 

extending service intervals and reducing maintenance frequency.

· Low Initial Pressure Drop: The media's open structure minimizes flow resistance when clean, optimizing system efficiency

 and reducing energy consumption.

· Chemical Compatibility: Glass fiber is compatible with a wide range of hydraulic fluids, including water-glycol mixtures,

 phosphate esters, and mineral oils, without degradation or media migration.

Application Fields

The PLF.BH-H160×10P is deployed across numerous industries requiring high-pressure hydraulic filtration:

· Steel and Metallurgy: Hydraulic systems in rolling mills, continuous casting machines, and forging presses

· Power Generation: Turbine control systems, EHC (Electro-Hydraulic Control) circuits, and steam valve actuators

· Offshore and Marine: Subsea control systems, deck machinery, and dynamic positioning thrusters

· Heavy Machinery: Injection molding machines, hydraulic presses, and material handling equipment

· Petrochemical: Pump station hydraulic systems and critical process control circuits

Frequently Asked Questions

Q1: What is the filtration accuracy of the PLF.BH-H160×10P?

The filter provides a nominal filtration accuracy of 10 μm (absolute). This level is suitable for protecting most industrial

 hydraulic components, including proportional and servo-valves. For applications requiring finer filtration, please contact 

our technical team for alternative element options.

Q2: Can the PLF.BH-H160×10P be used with fluids other than those listed?

The standard configuration is designed for water-glycol fluids, general hydraulic oils, and phosphate ester hydraulic oils. 

For other fluid types, including synthetic oils or special fire-resistant fluids, please consult our engineering team to verify 

seal material compatibility and element media suitability.

Q3: How does the differential pressure transmitter work?

The transmitter measures the pressure difference between the filter inlet and outlet. As the filter element accumulates

 contaminants, this differential pressure rises. When the preset alarm point is reached (typically 0.3–0.5 MPa above clean 

differential pressure), the transmitter sends an electrical signal or activates a visual indicator. This signal can be integrated 

with plant SCADA or DCS systems for remote monitoring and condition-based maintenance scheduling.

Q4: What is the bypass valve set pressure?

The bypass valve is factory-preset to open at a differential pressure of approximately 0.5–0.6 MPa. This setting ensures that 

bypass activation occurs only after the differential pressure alarm has been triggered and sufficient time has been allowed 

for maintenance action.

Q5: How often should the filter element be replaced?

Replacement intervals depend on system contamination levels, operating hours, and fluid condition. We recommend 

monitoring the differential pressure transmitter signal and replacing the element when the alarm activates. 

If no transmitter is installed, scheduled inspection every 1,000–2,000 operating hours is advisable, with replacement indicated 

by elevated pressure drop.

Q6: Can I change the filter element without completely draining the system?

Yes. The filter design includes a drain port and the bypass valve prevents complete fluid loss. However, some oil drainage 

is necessary for bottom-access element changes. For top-access replacements, minimal fluid loss occurs. Always depressurize

 the system before performing any maintenance.

Q7: Is the filter element reusable or cleanable?

The glass fiber filter element is a disposable component. Due to the depth-loading filtration mechanism, cleaning is not

 effective and may damage the media structure. Always replace with a genuine manufacturer-approved element to ensure

 specified performance.

Q8: What if my installation requires a different flow direction?

The cover can be rotated 180 degrees by removing the four cover screws, rotating the assembly, and reattaching. This simple 

modification reverses the flow direction without the need for additional piping modifications or special adapters.

Q9: What maintenance procedures are recommended for the bypass valve and transmitter?

The bypass valve is a mechanical safety device that requires minimal maintenance. The transmitter should be checked 

periodically for correct electrical output and calibration, especially after element replacements. We recommend annual 

functional testing of the signaling device.

Q10: Can the filter be used in outdoor or harsh environmental conditions?

Yes. The PLF.BH-H160×10P features a robust housing with corrosion-resistant coatings suitable for industrial environments. 

For extreme conditions (coastal, chemical exposure, or high humidity), optional upgraded coatings and materials are available 

upon request.
