New programme
Wandfluh has revised the existing 2-way cartridge valve programme and equipped it with massively higher pressure resistance. In addition, the flow geometry has been optimized and thus the flow rate considerably increased.
The valve programme comprises the 5 nominal sizes NG16, 25, 32, 40 and 50, which cover the volume flow range from 360 l/min (NG16) to 2,500 l/min (NG50) and switch up to 630 bar.
The cartridge valve is available as a seat-tight directional function. A version with a damped spool allows the valve to close more smoothly, resulting in lower pressure shocks in the system.
Also available is a pressure relief function that opens the valve at an individually adjusted pilot pressure independent of the flow. The pressure can be fix adjusted with a manually operated valve, or continuously variable and remote controlled with a proportional valve.
2-way built-in valves are particularly compact logic valves for block construction. This allows a wide range of hydraulic functions to be realised in the smallest of spaces for applications requiring high flows. The valves are installed in a cavity according to ISO 7368 and closed with a cover in which the pilot valve is usually installed.
