Introduction

The SDRLF series filter is composed of two single bowl filters and a 2-position 6-way directional valve. It is simple in structure and easy to use. There is by-pass valve and a contamination indicator for protecting the hydraulic system.

The feature of this filter allows continues operation even during replacing element clogged by contaminants. Turning the directional valve, another filter will be working in the hydraulic system, the clogged element should be changed in time.

This series is widely used in the hydraulic systems of heavy duty, mining and metallurgical machines.
