Technical Description
The 25 series UltraFlo valve enables this single handed, quick connect coupling to be used in applications where higher flow rates are required. Although similar to the 21 series, the 25 series is an excellent solution for the problem of connecting different media. Four standard codes matching the coupling and the respective plug ensure that media are not mixed up when connecting. Double shut-off and straight-through couplings are available upon request. Cannot be interconnected with the RECTUS standard 25 series.

Advantages
A quality coupling with compact dimensions. Single handed operation, high flow rate for its size. Multiple options for connecting.

Working Pressure
PB = 35 bar, maximum static
working pressure with safety
factor of 4 to 1.

Working Temperature*
-20°C up to +100°C (NBR)
