Valve B2508/0504/4808-OF DC
The type 25 solenoid valve is servo-controlled. The sealing element is a metal piston or flat disk with ring-shaped seat sealing. The piston is guided into the valve bonnet by means of special PTFE piston guids and grooved rings. This is a robust valve type which is suitable for high pressures and for a large field of application as many different sealing materials have been used.
