Introduction

PLF series High Pressure line filters introduction

PLF series filter is of high pressure type, and used in the pressure line of hydraulic system. It can remove all the contaminants from the hydraulic system.The element of this series is made of glass fibre. It has high efficiency and filtration,large dirt capacity and low initial pressure drop. Beta ratio is over 200.It has two protection equipment which are by-pass valve and contamination indicator. he indicator will act when the pressure drop across element attains adjustable pressure. The element should be cleaned or changed in time. Compare to other filters, this kind of filter is designed into small size. It can be used in different pressure levels and can be easily installed and the filter element also canbe easily changed.

Application

PLF series High Pressure line filters application

Hydraulic Systems: PLF filters are widely used across various hydraulic systems to maintain fluid cleanliness and ensure reliable operation. This is their primary function. Automatic Control and Servo Systems: They are especially suitable for high-precision control systems, such as automatic control and servo systems, where preventing premature wear or sticking of delicate components is critical. Protection of Sensitive Components: The filters are installed upstream of dirt-sensitive and expensive components (like pumps, valves, and cylinders) to protect them from mechanical impurities and internally generated contaminants, thereby extending their service life and reducing maintenance costs.

Feature

PLF series High Pressure line filters feature

High Filtration Efficiency:

The filter element is typically made of high-quality glass fiber or chemical fiber, providing high filtration efficiency and an absolute filtration rating.

Contamination Control:

It effectively removes solid particles and impurities generated within the system, ensuring the stable operation and extending the service life of hydraulic components.

High Pressure Capability:

The housing is designed to withstand high operating pressures, commonly in ranges such as 6.3 MPa, 16 MPa, and 32 MPa.

Bypass Valve:

An automatic bypass valve acts to protect the filter and system integrity if the filter element becomes completely clogged, preventing excessive pressure buildup and ensuring continued, albeit unfiltered, flow.
