German Limitorque valves Limitorque models Limitorque prices

Limitorque valves include vacuum ball valves, vacuum baffle valves, vacuum venting valves, pneumatic vacuum valves, etc. Their function in a vacuum system is to change the direction of airflow, regulate the flow rate, and cut off or connect pipelines; such components are called vacuum valves.

Limitorque valve connection method: Flange connection

This is the most commonly used connection form for valves. According to the shape of the mating surface, it can be divided into the following types: 1) Smooth type: Used for valves with low pressure. Easy to process. 2) Male-female type: For higher working pressure, medium-hard gaskets can be used. 3) Tongue-and-groove type: Gaskets with greater plastic deformation can be used; widely used in corrosive media with good sealing effect. 4) Trapezoidal groove type: Uses oval metal rings as gaskets, suitable 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, offering effective sealing.

Limitorque 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 machining burrs, etc.; 2) All components undergo degreasing treatment; 3) After degreasing, perform acid pickling and passivation; the cleaning agent must not contain phosphorus; 4) After acid 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 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 stains remain.

Limitorque valve fault resolution

Ball valves have long been subject to material erosion and friction, causing severe impact wear, failing to meet normal production requirements, and shortening equipment service life. Currently, wear-resistant materials such as ceramics and polymer composites are often used to address ball valve wear, with established technical systems applied. Polymer materials offer superior adhesion and extreme wear resistance, safely solving the frequent wear problems of metals and ensuring normal enterprise production. Moreover, the unique ceramic materials and special surface hardeners in these materials provide wear and physical impact resistance in the harshest dry grinding environments that surpass any steel or even tiles. The product's non-adhesion to coal makes it an ideal material for preventing coal buildup.
