Applications 应用
HZ-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 makeshift themideal for use in these types of hostile environments.
HZ-FF系列接头广泛用于以下公用设施: 液压油泄漏会构成严重的安全险情，尤其对用于高
压电源输送线维护的架空斗式起重机。这类接头还用于建筑、铁路维护及矿业中的液压机
具之快速切换，易于清理使之能理想地用于这类特殊环境

Features 特征
New valve design, it cans resistance damage from high flow and the pressure of impulse that
providing advanced performance.
Sleeve locking mechanism is engaged by rotating sleeve after connection. It prevents accidental
disconnection when coupling is dragged along the ground.
Sleeve mechanism is designed to help prevent dirt from entering the internal mechanism and
thus causing faulty operation when connecting or disconnecting. The sleeve covers the retaining
ring and also incorpor ates a dust seal in the springarea.
Hardened nipples and sleeves and solid barstock construction make for a quality coupling with
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.
Durable ball-locking mechanism assures reliable connection every time. A largenumber of
locking balls distributes and work load evenly while providing alignmentand swiveling action
to reduce hose torque and prolong hose life. CAUTION: Theseproducts are not to be used as
swivels; rotation under pressure will result in excessive and premature wear.
HZ-FF Series couplings employ flush valving when connecting or disco nnecting. This means
that the valves are mated together so that only small amounts of fluid can be lost during
disconnection or air inclusion during reconnection.
New chrome plating treatment provides advanced anti-rust performance.
HZ-FF Series conforms to the standard of ISO16028.
Compatible with PARKER FE, FF Series, STUCCHI A8008 Series, AEROQUIP FD89 Series and
HANSEN QA2900 Series.
