Abstract: Testing of regulating valves to determine their flow and cavitation characteristics in order to make a practical and economic selection of valves for use in hydraulics control is described. It is essential that the change in cavitation characteristics with a change in upstream head be considered. Care should be exercised in the use of butterfly valves, vanes, or struts downstream of throttling valves because of the helical flow pattern caused by the throttling action. The vertical sleeve valve eliminates the problems of noise, vibration, and spray and can therefore be used in populated areas without difficulty. Savings have resulted from the development of valve details that have lowered valve costs. Additional savings are anticipated from the development of the vertical sleeve valve.
