German Eugen Seitz valves, Eugen Seitz models, Eugen Seitz prices

Eugen Seitz valves use liquid as the working medium to transmit energy and perform control. Hydraulic transmission and pneumatic transmission are collectively known 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 applied in industrial and agricultural production.

Advantages of Eugen Seitz valves

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

Daily maintenance of Eugen Seitz valves

1) Pay attention to the valve storage environment; it should be stored in a dry and ventilated indoor area, with both ends of the flow path blocked. 2) Valves should be inspected regularly, cleaned of dirt, and coated with anti-rust oil on their surfaces. 3) Valves that have been installed and put into use should undergo regular maintenance to ensure normal operation. 4) Check whether the valve sealing surface is worn, and repair or replace it as necessary. 5) Check the wear condition of the trapezoidal threads on the valve stem and valve stem nut, and whether the packing is outdated or failed, and perform necessary replacements. 6) Test the sealing performance of the valve to ensure its integrity. 7) Valves in operation should be in good condition, with all bolts on flanges and supports complete, threads undamaged, and no loosening. 8) If the handwheel is lost, it should be replaced promptly; do not use an adjustable wrench as a substitute. 9) The packing gland must not be skewed or lack pre-tightening clearance. 10) If the valve operating environment is harsh and prone to contamination by rain, snow, dust, sand, etc., a protective cover should be installed on the valve stem. 11) The scale on the valve should remain complete, accurate, and clear; check the valve's lead seal and cap. 12) The insulation jacket should have no dents or cracks. 13) Avoid striking valves in operation or supporting heavy weights on them.

Application and maintenance of Eugen Seitz valves

Over time, hydraulic valves will inevitably experience some failures, which involves the maintenance of hydraulic valves. In actual production, maintenance of hydraulic valves mainly involves timely cleaning, selective assembly of some parts, and dimensional repair. Oil fluid in the channels of hydraulic valves can easily precipitate, causing unnecessary failures. Therefore, we must clean them promptly by disassembling and washing the hydraulic valve to restore its function in a timely manner. Safety must be observed during cleaning; many sediments are difficult to clean and require cleaning fluids, which are often corrosive, toxic, or even flammable, so caution is essential. Parts cleaned must be properly stored to prevent further corrosion. After cleaning and reassembly, the hydraulic valve can continue to operate after testing. If some parts of the hydraulic valve are damaged severely, selective reassembly is generally chosen. If hydraulic valves are maintained by specialized, experienced personnel, their service life will be greatly increased, and their reliability and performance will remain at original levels. Even so, we must remain vigilant in daily production to prevent accidental incidents.
