German AVENTICS valves AVENTICS models AVENTICS prices

AVENTICS valves use liquid as the working medium to transmit energy and perform control. Hydraulic transmission and pneumatic transmission are collectively referred to as fluid power transmission. This is an emerging technology developed based on the principle of hydrostatic pressure transmission proposed by Pascal in the 17th century, and it is widely used in industrial and agricultural production.

AVENTICS valve advantages

Hydraulic transmission has many outstanding advantages, so its application is very wide, such as plastic processing machinery, pressure machinery, machine tools, etc. for general industry; construction machinery, building machinery, agricultural machinery, automobiles, etc. in mobile machinery; metallurgical machinery, lifting devices, roll adjustment devices, etc. for the steel industry; flood control gates and dam devices, riverbed lifting devices, bridge operating mechanisms, etc. for civil and hydraulic engineering; turbine speed governing devices for power plants, etc.; deck cranes, bow doors, bulkhead valves, stern thrusters, etc. for ships; control devices, measuring buoys, lifting and rotating stages, etc. for special technologies; artillery operating devices, ship stabilizers, flight simulators, landing gear retraction and extension devices, and rudder control devices, etc. for the military industry.

AVENTICS valve daily maintenance

1) The valve storage environment requires attention; valves should be stored in a dry, ventilated indoor location, with both ends of the flow passages blocked. 2) Valves should be inspected regularly to remove dirt and apply anti-rust oil to their surfaces. 3) Valves that have been installed and put into service should undergo regular maintenance to ensure proper operation. 4) Inspect the valve sealing surfaces for wear, and repair or replace them as necessary. 5) Check the trapezoidal threads of the valve stem and stem nut for wear, and verify whether the packing is outdated or has failed, replacing components as necessary. 6) Test the sealing performance of the valve to ensure its integrity. 7) Valves in operation must be in good condition, with all bolts on flanges and supports present, threads undamaged, and no looseness. 8) If the handwheel is missing, it should be replaced promptly; an adjustable wrench must not be used as a substitute. 9) The packing gland must not be skewed and must have the specified preload clearance. 10) If the valve operating environment is harsh and prone to contamination by rain, snow, dust, or sand, a protective cover should be installed on the valve stem. 11) The scale on the valve must remain complete, accurate, and clear; ensure the valve's lead seal and cap are intact. 12) The insulation jacket must be free of dents and cracks. 13) For valves in operation, avoid striking them or supporting heavy loads on them.

AVENTICS valve application and maintenance

Over time, hydraulic valves will inevitably experience some failures, which involves the maintenance of hydraulic valves. In actual production, the maintenance of hydraulic valves mainly involves timely cleaning, selective assembly of some parts, and dimensional repair. There is oil in the channels of hydraulic valves, which can easily lead to oil sedimentation. These sediments can cause unnecessary failures in hydraulic valves, so we must clean them in time. Disassemble and clean the hydraulic valve to restore its function in time. Pay attention to safety during cleaning. Many sediments are difficult to clean and require cleaning fluids. These cleaning fluids are generally corrosive or toxic, and some are even flammable, so caution is required. Properly store the cleaned parts to prevent further corrosion. After cleaning and installation, the hydraulic valve can continue to operate after testing. If some parts of the hydraulic valve are damaged and the damage is severe, re-assembly and selective matching are generally chosen. If hydraulic valves are maintained by specialized and experienced personnel, their service life will be greatly increased, and their reliability and working performance will be maintained at the original level. Even so, we must remain vigilant in daily production to prevent accidental accidents.
