Valtek control valve flow capacity (C v) is based upon the industry standard, ANSI/ISA S75.01. This standard and the corresponding measuring standards contain Equations used to predict the flow of compressible and incompressible fluids in control valves. Slightly differ-ent forms of the basic Equation are used for liquids and gases.

The Model 9000 valve is an ANSI Class 300 globe style valve with bolted bonnet and post guided innervalve. The valve is designed for a variety of industrial applications. The body, bonnet and innervalve are standard in 316SST or optional Alloy C. control valve specification sheets, took the most popular fields, and worked with Intergraph to create SPI Form 90, the standard control valve spec sheet for Fisher products. (The ISA control valve spec sheet in SPI is rarely used on projects since it lacks many fields needed by EPC’s.) in the upper control chamber is vented. This, together with the line pressure acting on the seal-disk, creates a force that powers the valve to the open position. Open Position The open pilot valve releases line pressure from the upper control chamber. The line pressure acting on both the lower control chamber and the seal-disk, moves the valve ...
