The appearance of the valve is much like what the name implies—a butterfly. Essentially, it is a metal disc mounted on a rod. The rod goes down the center of the disc and appears as the body of a butterfly with the two disc halves as the wings on each side.

Function

    1. In the closed position, which is achieved by rotating the valve a quarter turn, the disc blocks off the pipe or passageway in which it is mounted. Unrestricted flow or passage occurs when another quarter turn of the valve opens the disc. Control of the opening or closing is outside of the valve

Uses

    1. Butterfly valve use occurs throughout our daily life. Probably the most common is within the car carburetor. The gas pedal is the outside source that controls the air-intake valve (butterfly) to make your car go. Many industrial machines depend on butterfly valves as part of their operation. Applications where steam, liquids, gas or air need to be controlled rely on butterfly valves.

Types

    1. Depending on the usage and pressure encountered, butterfly valves come in a wide assortment—from resilient (which uses the flexibility of rubber), to low or high pressure (tricentric) valves, industrial, wafer, plastic to stainless steel and manual or automatic.

Problems

    1. The inability to thoroughly remove all residual substances due to its design is a drawback to using the butterfly valve in some situations. Highly corrosive or abrasive material will wear a valve down quickly; the valves are not recommended for those types of application. Improper (or careless) installation often leads to complaints about the butterfly valve.

Benefits

  1. There are many benefits in the use of a butterfly valve. On the whole they are priced lower than other types of valves. Due to the minimum parts involved in a butterfly valve they have a long operational life and are reliable. Their simple design makes them easy to maintain. Most butterfly valves are lightweight and compact. Butterfly valves are designed to withstand a wide range of temperatures and still work.

ACTUATOR: A fluid-powered or electrically powered device that supplies force and motion to a VALVE CLOSURE MEMBER.

AIR SET: Also SUPPLY PRESSURE REGULATOR. A device used to reduce plant air supply to valve POSITIONERS and other control equipment. Common reduced air supply pressures are 20 and 35 psig.

AIR-TO-CLOSE: An increase in air pressure to the ACTUATOR is required to cause the valve to close. This is another way of saying the valve is Fail Open or Normally Open.

AIR-TO-OPEN: An increase in air pressure to the ACTUATOR is required to cause the valve to open. This is another way of saying the valve is FAIL CLOSED or NORMALLY CLOSED.

ANSI: An abbreviation for the American National Standards Institute.

ANTI-CAVITATION TRIM: A special trim used in CONTROL VALVES to stage the pressure drop through the valve, which will either prevent the CAVITATION from occurring or direct the bubbles that are formed to the center of the flow stream away from the valve BODY and TRIM. This is usually accomplished by causing the fluid to travel along a torturous path or through successively smaller orifices or a combination of both.

API: An abbreviation for the American Petroleum Institute.

ASME: An abbreviation for the American Society of Mechanical Engineers.

ASTM: An abbreviation for the American Society for Testing and Materials.
