An optimized Hydraulic Filter is essential for the reliable operation of steam turbine Electro-Hydraulic (EH) control systems, where oil cleanliness is a non-negotiable safety factor. Power plants rely on EH oil (typically fire-resistant phosphate ester) to modulate turbine valves. Even microscopic silt or varnish can cause valve sticking, leading to load swings or emergency trips. As an expert in famous brand equivalents, we understand the critical nature of these components.
The Harsh Environment of EH SystemsHigh temperatures and moisture often lead to the degradation of EH oil, forming acidic byproducts and varnish. Our hydraulic elements are specifically designed with anti-static media and high-strength support cores to withstand the aggressive nature of phosphate esters.
Why Choose Lefilter Hydraulic Elements?
Media Integrity: We use inorganic glass fiber that does not react with synthetic oils.
High Collapse Strength: Our cores are rated for up to 210 bar, ensuring the filter doesn't collapse during cold starts or pressure surges.
ISO 16889 Testing: Every batch is validated for Multi-pass performance to guarantee consistent micron ratings.
By maintaining "NAS 5" or better oil cleanliness, power plants can extend the interval between major turbine overhauls and reduce the risk of unplanned outages.
