SDRLF duplex large flow rate return filter series
Introduction to SDRLF duplex large flow rate return filter series
The SDRLF duplex large flow rate return filter series consists of two single tube filters and a two position six position directional valve, with a simple structure and convenient use. It is equipped with a bypass valve and a filter clogging transmitter to ensure system safety. This type of filter is widely used in hydraulic systems such as heavy-duty machinery, mining machinery, metallurgical machinery, etc., and is particularly suitable for hydraulic systems that require continuous operation.
Performance of SDRLF duplex large flow rate return filter series
The SDRLF duplex large flow rate return filter series has excellent filtration performance. The filtering materials for its filter element are composite inorganic fibers, stainless steel woven mesh, and stainless steel fiber felt, which can be selected according to specific situations and effectively filter out impurities in the working medium. In addition, the material of the filter housing is low-carbon steel, and stainless steel processing can also be used as needed. The working temperature range is -30~110 ℃, which can adapt to various working environments.

Characteristics of SDRLF duplex large flow rate return filter series
1.Dual cylinder design: The SDRLF duplex large flow rate return filter series adopts a dual cylinder design. When one filter element is clogged and needs to be replaced, there is no need to stop the main engine. Just open the pressure balance valve and rotate it.
2. The directional valve allows the other filter to start working, achieving non-stop replacement of the filter element and ensuring normal and continuous operation of the main engine.
3. High filtration efficiency: This filter can effectively filter out solid particles and gel like substances in the working medium, providing 1-30 μ The filtration accuracy of m ensures the cleanliness of the hydraulic system.
4. High safety: Equipped with a bypass valve and a filter clogged transmitter, when the filter is clogged to a certain extent, the transmitter will send a signal to remind timely replacement of the filter to avoid system contamination and ensure system safety.
SDRLF duplex large flow rate return filter series usage range
The SDRLF duplex large flow rate return filter series is suitable for various working media, including general hydraulic oil, phosphate hydraulic oil, emulsion, water hexanediol, etc. Its flow rate range is between 1300-9100L/min, which can meet the needs of different large-scale hydraulic systems. Therefore, it is widely used in hydraulic systems that require efficient filtration and continuous operation, such as heavy-duty machinery, mining machinery, metallurgical machinery, etc.
