Technical Datasheet -- Cage-Guided Globe Control Valves for Process Throttling Service
Single-seated piston-type globe control valves for process control and throttling service. Cage-guided plug provides excellent rangeability (50:1 standard, up to 100:1 with micro-flow trim) and anti-cavitation / anti-noise trim options for high-pressure differential applications. SS316 or WCB body with pneumatic diaphragm, piston, electric, or hydraulic actuator. Smart digital positioner with HART / Fieldbus / Profibus and valve diagnostics. ISA S75 / IEC 60534 compliant.
