Seat Valve Electrically servo-assistent
Series 54-08-TH
Valve A5403/0804/.012-NW AC, DC

The type 54-TH is servo-controlled. The sealing element is a metal piston or flat disk with ring-shaped seat sealing made from PTFE. The piston is guided into the valve bonnet by means of special piston guids and grooved rings. This is a robust valve type which is suitable for high pressures and high temperatures up to +180°C. A differencial pressure 0,5 bar between inlet and outlet is required for the operation. Valve is sensor-ready, configurable with end position detection as option -6H or for retrofitting.
