05, buttweld;, Valtek uses a systematic method for selecting body types, sizes, materials, pressure ratings and trim sizes based on flow characteristics.

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.

23 Cv 16 129 430 946 1640 2580 3870 5420 6970 8600, Valtek has programmed the ANSI/ISA sizing Equations and procedures, making computer-aided sizing avail-able on IBM-PC or compatible computers.

These programs permit rapid control valve flow capacity calcu-lations and valve selection with minimal effort.

The programs also include exit velocity, noise prediction and actuator sizing calculations.

The Valtek Mark One control valve is the industry choice for a simple, reliable, tough globe valve.

The Valtek Mark One TM globe control valve offers superior performance in liquid and gaseous services, while also permitting easy, fast and inexpensive maintenance.

, 17/12/2013 The Valtek GS is an environmentally-friendly control valve that complies with the latest standards for controlling fugitive emissions requirements (ISO 15848).

The GS provides automated calibration and high flow rates – over 55 Cv in a 2-inch valve and nearly 150 Cv in the 3-inch model.
