Seat Valve Electrically servo-assistent
Series 51-08-TH
Valve C5128/0804/.802-NW AC, DC
Solenoid valve for industrial applications with high flow rates. The robust servo-piston design is available in nominal sizes DN10 to DN50 and can be supplied in either normally closed (NC) or normally open (NO) versions. PTFE seals allow use with media temperatures up to 180 °C. Due to the servo-operated design, a minimum differential pressure of 1 bar is required for reliable operation. The valve is designed as Sensor-Ready and can be equipped with a position feedback system. This function is available as factory option -6H or can be retrofitted at any time. This makes the valve particularly suitable for systems with condition monitoring and digital feedback.
