Overview The model AC2 low leakage pressure balanced cage type control valves are designed for heavy duty service. The valve plug employs pressure balance structure to control high differential pressure fluid with small actuator force. The AC2 realizes seat leakage performance IEC class V per IEC60534-4 by flexible-seat structure. The actuator is adopted a compact and powerful diaphragm motor. The AC2 is applicable for high differential pressure process line where low seat leakage performance is required.
