    Training Purpose

    There are many different types of valves and the correctselection is imperative. Selection of the incorrect valve orsealing concepts may have an impact on safety, reliability,cost, and schedule.cost, and schedule.

    Valves used in todays projects are increasingly complex. Theprocess conditions material limitations and specificationprocess conditions, material limitations, and specificationregulations play into the difficulty of valve selection.Understanding the basic drivers behind valve design andmaterial selections will offer competitive advantages for allate a se ect o s o e co pet t e ad a tages o aparties of the supply chain.

  • History

    Evidence of valves can be traced back to the times of the ancient Egyptians and Greeks. It is the Romans, however, who are generally

    i d th d l f ti l hi ti t d t


    recognized as the developers of comparatively sophisticated water systems. Their plumbing was advanced enough to deliver water into individual buildings, for which they developed the plug valve, or stopcock, and there is also evidence that the Romans used check valves to prevent back flowto prevent back flow.

  • History (cont )The basic philosophy remains the same today. Along with advances in technology, the design of the valve has become increasingly sophisticated. The dawn of the oil boom saw a large usage of simple

    History (cont.)

    p g g pgate and plug valves. These type of valves are still in use in many applications. Many of the large gate valves have given way to ball valves. Ball valves have a lower profile (more compact) and have overall greater cost advantages.

  • What valves look like

    In a P&ID:

    What valves look like...

    In engineering: In a submitted drawing:

    In manufacturing: In the field:

  • Types of Valves (covered in this training)

    Ball Spherical obturator used in

    Types of Valves (covered in this training)

    Ball Spherical obturator used in combination with a seat (or seats) to stop/allow flow. The ball is supported by trunnion using floating seats in a Trunnionball al e Floating ball al es se a floatingball valve. Floating ball valves use a floating ball that seats on a stationary sealing surface.

    Plug Similar to a ball valve, a plug valve has cylindrical or conically-tapered "plugs" which can be rotated inside the valve body tocan be rotated inside the valve body to control flow through the valve. With the absence of soft seals in the flow path, these valves are ideal for abrasive service.

  • Types of Valves (covered in this training)

    Gate - Opens by lifting a round or

    p y grectangular gate/wedge out of the path of the fluid.

    Check Used to prevent backflow. A clapper is used to shut with opposing pressure (or assisted by gravity).

  • Types of Valves (outside this training)

    Butterfly - A flat circular plate is positioned in the center of the pipe The plate has a rod through it

    Types of Valves (outside this training)

    center of the pipe. The plate has a rod through it connected to a handle on the outside of the valve. Rotating the handle turns the plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flowthe plate is always present within the flow

    Globe - Consists of a movable disk-type element and a stationary ring seat in a generally spherical body. It has an opening in the body that forms a y p g yseat onto which a movable plug can be screwed in to close (or shut) the valve.

  • Types of Valves (outside this training)

    Double Ball Double Block and Bleed Consisting of

    gtwo balls within the valve, this instrumentation valve is typically used on small instrumentation double block and bleed applications.

    Double Piston Effect is a design whereby pressure in the cavity energizes the downstream seat and effects a downstream seal. DPE seats result in athe downstream seat and effects a downstream seal. DPE seats result in a

    double barrier within a single valve. Valves in liquid service with DPE seats must pipe-away the cavity pressure

    to the upstream side of the valve to prevent damage from thermal expansionexpansion.
