In today's unpredictable economy, the In today's unpredictable economy, the selection of valves can become monumental selection of valves can become monumental task. For many, It was never easy to begin task. For many, It was never easy to begin with, especially when there are so many with, especially when there are so many types to choose from .This article will help types to choose from .This article will help facilitate the basics of valve selection and facilitate the basics of valve selection and give some insight into what might be give some insight into what might be expected in future valve selection.expected in future valve selection.For all practical purposed, For all practical purposed, a valve considered a valve considered as advice which stop starts or changes as advice which stop starts or changes direction or magnitude of fluid flows or its direction or magnitude of fluid flows or its pressure and temperaturepressure and temperature.. This description in This description in itself is perhaps sufficient to explain some of itself is perhaps sufficient to explain some of the reasons that make valve selection such an the reasons that make valve selection such an arduous task, but let's ask ourselves five arduous task, but let's ask ourselves five basic questionbasic question

1- 1- THE PRINCIPAL FUNCTIONS OF VALVES STARTING THE PRINCIPAL FUNCTIONS OF VALVES STARTING AND STOPPING FLOWAND STOPPING FLOW

This is the service for which valves are most This is the service for which valves are most generally used—starting and stopping flow. Gate generally used—starting and stopping flow. Gate valves are excellently suited for such service. Their valves are excellently suited for such service. Their seating design, when open, permits fluid to move seating design, when open, permits fluid to move through the valve in a straight line with minimum through the valve in a straight line with minimum restriction of flow and loss of pressure at the valve.restriction of flow and loss of pressure at the valve.

2- REGULATING OR THROTTLING FLOW2- REGULATING OR THROTTLING FLOW Regulating or throttling flow is done most efficiently Regulating or throttling flow is done most efficiently

with globe or angle valves. Their seating design with globe or angle valves. Their seating design causes a change in direction of flow through the causes a change in direction of flow through the valve body, thereby increasing resistance to flow at valve body, thereby increasing resistance to flow at the valve. Globe and angle valve disc construction the valve. Globe and angle valve disc construction permits closer regulation of flow. These valves are permits closer regulation of flow. These valves are seldom used in sizes above 12 inches, owing to the seldom used in sizes above 12 inches, owing to the difficulty of opening and closing the larger valves difficulty of opening and closing the larger valves against pressure.against pressure.
