Series 2/640 +400°C VA
Valve closed by spring force in rest position - NC. When the actuator (cylinder) is pressurised the piston (spindle) is lifted of the seat (orifice) directly. Further function like normal open by spring force (NO) is also available. High temperature design up to +400°C with metallic seat sealing and static wills-ring.
