Basic Info of Position Sensor Butterfly Valve
- Replaceable seat: allows for quick repairs without replacing the entire valve, saving costs and reducing downtime.
- Enhanced Sealing: Rubber seats provide excellent sealing performance, often achieving zero leakage (e.g., EN 12266 leak rate A).
- Position sensor: is often paired with actuators for automated control, with ISO 5211 mounting flanges for compatibility.
- Precise Control: Position sensors for butterfly valve enable accurate monitoring and control, ideal for automated systems or critical processes.
- Butterfly Valve with Position Sensor: A position sensor (e.g., limit switch) provides real-time feedback on the valve’s disc position (open, closed, or partially open).
Advantage of Butterfly Valve with Position Sensor:
- Durability: The ductile iron and CF8 stainless steel ensure a long service life.
- Leak-Free Performance: The replaceable soft seat butterfly valve ensures leak-free operation.
- Easy Maintenance: The replaceable soft seat simplifies maintenance and reduces overall costs.
- Corrosion Resistance: Both the body and disc are corrosion-resistant, making this valve ideal for use in water and wastewater systems.
