Quick coupling LSQ-FF series

hydraulicsteel

Songqiao LSQ-FF Series couplings are widely used in the public utility market where hydraulic oil spillage can constitute a serious safety hazard, particularly in overhead bucket hoists that are used for maintenance of high-voltage power transmission lines.These couplings are also used for quick change of hydraulic Tools in construction, railway maintenance and mining industries. The ease of cleaning makes them ideal for use in these types of hostile environments. 1, New valve design, it can resistance damage from high flow and the pressure of impulse that providing advanced performance. 2, Sleeve locking mechanism is engaged by rotating sleeve after connection. It prevents accidental disconnection when the coupling is dragged along the ground. 3, Sleeve mechanism and designed to prevent dirt from high flow entering the internal mechanism and thus causing faulty operation when connecting or disconnecting. The sleeve covers the retaining ring and also incorporates a dust seal in the spring area. 4, Steel construction, zinc plated finished and hardened nipples and sleeves and solid barstock construction for maximum resistance to damage from hydraulic and mechanical shock. This Anti –Blowout Nitrile/PTFE bonded seal is designed to prevent blow-out or damage during severe service conditions. 5, Durable ball-locking mechanism assures reliable connections every time. A large number of locking balls distributes the work load evenly while providing alignment and swiveling action to reduce hose torque and prolong hose life.
