It is installed in the low pressure pipeline or oil return pipeline of the hydraulic system to filter out the solid particles and colloidal substances in the working medium and effectively control the pollution degree of the working medium.
It is installed in the low pressure pipeline or oil return pipeline of the hydraulic system to filter out the solid particles and colloidal substances in the working medium and effectively control the pollution degree of the working medium.
LYPD series filters can be quickly switched through the flow piston rotary valve to achieve uninterrupted work. The piston type rotary valve moves in a straight line to ensure sealing, small resistance and flexible opening. The filter element is equipped with a bypass valve, and a pressure gauge or a differential pressure transmitter can be installed as required.
The filter element materials include fiber, kapok qualitative filter paper, stainless steel woven mesh and sintered felt.
The filter housing material is carbon steel, or stainless steel can be used as required.
Working medium | Mineral oil, emulsion, water glycol, phosphate ester hydraulic fluid (kapok qualitative filter paper is only suitable for mineral oil) |
Working pressure (maximum) | 1.6Mpa |
Transmitter differential pressure: | 0.3MPa |
Bypass valve opening differential pressure | 0.35Mpa |
