German LUKAS Hydraulik valves, LUKAS Hydraulik models, LUKAS Hydraulik prices

LUKAS Hydraulik valves include vacuum ball valves, vacuum baffle valves, vacuum inflation valves, and pneumatic vacuum valves. In a vacuum system, components used to change the direction of airflow, regulate the flow rate, or isolate or connect pipelines are referred to as vacuum valves.

LUKAS Hydraulik valve connection methods: Flange connection

This is the most commonly used connection form for valves. According to the shape of the joint surface, it can be divided into the following types: 1) Smooth type: Used for valves with low pressure. Easy to process. 2) Concave-convex type: Higher working pressure, medium-hard gaskets can be used. 3) Tongue-and-groove type: Gaskets with large plastic deformation can be used. Widely used in corrosive media, with good sealing effect. 4) Trapezoidal groove type: Oval metal rings are used as gaskets, used for valves with working pressure ≥ 64 kg/cm², or high-temperature valves. 5) Lens type: The gasket is lens-shaped and made of metal. Used for high-pressure valves with working pressure ≥ 100 kg/cm², or high-temperature valves. 6) O-ring type: This is a newer flange connection form, developed with the emergence of various rubber O rings. It is a sealing connection form.

LUKAS Hydraulik valve cleaning steps

Valve components must undergo the following processes before assembly: 1) According to processing requirements, some components need polishing; the surface must not have processing burrs, etc.; 2) All components undergo degreasing treatment; 3) After degreasing, pickling and passivation are performed; the cleaning agent does not contain phosphorus; 4) After pickling and passivation, rinse thoroughly with pure water to ensure no chemical residue remains; this step is omitted for carbon steel components; 5) Wipe each component dry with non-woven fabric, ensuring no lint remains on the component surface, or blow dry with clean nitrogen; 6) Wipe each component with non-woven fabric or precision filter paper soaked in analytically pure alcohol until no dirt color remains.

LUKAS Hydraulik valve fault resolution

Ball valves have long been subject to material scouring, causing friction and severe impact wear, which fails to meet normal production requirements and shortens equipment service life. Currently, wear-resistant materials such as ceramics and polymer composites are widely adopted for ball valve wear. Polymer materials offer superior adhesion and ultra-high wear resistance, safely addressing the drawbacks of frequent metal wear and ensuring normal enterprise production. Moreover, the unique ceramic materials and special surface hardeners in the material provide wear and physical impact resistance in the harshest dry grinding environments that surpass any steel or even tiles. The product's non-affinity with coal makes it an ideal material for preventing coal accumulation.
