Quick-connect couplings for hydraulic systems

Description

Quick-connect couplings are meant for quick connection and disconnection of flexible pipes of hydraulics working under pressure of up to 200 bar.

The design feature of the couplings is 100% casing hermeticity when disconnected due to original valve configuration, reduced differential pressure by oil flow through the locking feature as against known analogies, 100% of assemblability and hermeticity when assembling with couplings of European manufacturers.

The design of the couplings is complies with GOST R 50191 and international standards ISO 5675, ISO 7241-1 in terms of connection sizes, they can be coupled with response parts of couplings by different manufacturers.

The couplings can be applied in MAZ-type mobile transports, tractors and other agricultural engineerings with towed vehicles. The couplings have passed tests on "Minsk Tractor Works", "Minsk Automobile Plant", "Lidagroprommash", "Volgograd Tractor Plant" and are being applied for equipping arrangement of "Belarus" tractors, MAZ trucks and support vehicles, support vehicle of "Mogilevtransmash" plant.

The plant can supply quick-connect couplings with adaptors and other thread versions: metric, conic inch, piped cylindrical, piped conic.
