German Brocal valves Brocal models Brocal prices

Brocal 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.

Brocal 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 control 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 control devices, ship stabilizers, flight simulators, landing gear retraction and extension devices and rudder control devices, etc. for the military industry.

Brocal valve daily maintenance

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, and dirt should be removed from them, with anti-rust oil applied to their surfaces. 3) Valves that have been installed and put into use should undergo regular maintenance to ensure their normal operation. 4) Check whether the valve sealing surface is worn, and repair or replace it according to the situation. 5) Check the wear condition of the trapezoidal threads of the valve stem and valve stem nut, whether the packing is outdated or failed, etc., and make necessary replacements. 6) Test the sealing performance of the valve to ensure its performance. 7) Valves in operation should be in good condition, with complete bolts on flanges and supports, undamaged threads, and no looseness. 8) If the handwheel is lost, it should be replaced promptly, and an adjustable wrench should not be used 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 lead seal and cap. 12) The insulation jacket should have no dents or cracks. 13) For valves in operation, avoid knocking on them or supporting heavy weights on them.

Brocal valve application and maintenance

As time goes by, hydraulic valves will inevitably experience some faults, 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, and oil sedimentation can easily occur. 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 some cleaning fluids. These cleaning fluids are generally corrosive or toxic, and some are even flammable, so you must be cautious. Cleaned parts must be properly stored 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 serious, selective reassembly is 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.
