Parker快速接頭，Parker FEM SERIES無溢流型快速接頭，派克快速接頭的設計ISO 16028標準的設計及壓力要求。FEM標準件設計還可方便于選擇各種陽接頭，派克FEM接頭設計用于建筑，公用設施及農業設備。如所有派克平齊端面設計一樣，這種無溢流型快速接頭的特征在于它削除了連接或斷開液壓附件時出現的液壓泄漏和夾氣。FEM系列可理想地用于許多其他應用，這類應用的特征是液壓泄漏為一關注問題而且與其他制造廠家產品的普遍互換比較重要。陽接頭：碳鋼；表面處理：表面鍍白鋅；閥：平齊端面閥機構；密封件：抗爆裂丁晴橡膠

Technical Description
Non-valved couplings.
Maximal flow. Minimal pressure
drop. Easy cleaning.
This series is also manufactured
as an alternative in steel and
AISI 316 material.
Advantages
No valving allows minimal pressure
drop, maximal flow and
easy cleaning. The ball locking
mechanism with high number
of balls to distributes the work
load assures low wearing
and good alignement
of the
couplings. High resistance to
brinneling due to heat treated
nipples.

Working Temperature:-40°C up to +110°C (NBR)
depending on the medium.
Special seals are available
