Fisher Controls 1" 150# CF8M ET Globe Control Valve with a Size 30i Fisher 667 Pneumatic Actuator and FIELDVUE Digital Valve Positioner
Rp123000.00
The listed unit is a high-performance Fisher Controls control valve assembly, commonly used in oil & gas, refining, and chemical processing applications where accurate flow regulation is critical. It consists of the following key components:
Fisher ET Control Valve – A 1-inch, ANSI 150#, CF8M stainless steel globe-style valve designed for throttling control of liquids, gases, and steam. The ET series is known for its rugged design, versatility, and capacity to handle moderate to severe service conditions.
Fisher 667 Size 30i Pneumatic Actuator – A spring-opposed diaphragm actuator providing linear motion. Known for its durability and reliable force generation, this actuator converts air pressure into mechanical force to modulate the valve stem.
FIELDVUE Digital Valve Positioner – A smart positioner that receives control signals and accurately positions the valve. It features diagnostics, performance monitoring, and integration with asset management systems, improving reliability and maintenance planning.
