Duplex Strainer

Duplex Strainer is composed of two high-flow and a 2-position 6-way directional valve. It is installed in low pressure or return pipelines of hydraulic & lube systems. This duplex basket strainer design is simple in construction and easy to use. Basket Type Duplex Strainer shaped like a basket and usually installed in a vertical cylinder.

There are a by-pass valve and a contamination indicator in this duplex basket strainer, for protecting the hydraulic system safety.

The maximum flow rate of 15000 1/min

Bypass-valve, clogging indicators

High dirt holding capacity and easy maintenance

Continuous operation due to duplex change-over filters design

Filter housing adopts high-quality steel or stainless steel.

Large ball valve changeovers available

The feature of duplex basket strainer allows for continuous operation when changing elements due to clogging caused by contaminants.

These series of duplex basket strainer have a high flow range from 1300 l/min to 15000 l/min with maximum pressure 1.6 Mpa. MVS duplex basket strainers are widely used in the hydraulic systems of heavy-duty mining and metallurgical machines. The relevant degree of filtration is provided by welding the appropriate grade of Stainless Steel mesh to the basket
