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 today’s 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

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

Types of Valves (covered in this training)

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 ‘floating’ball 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).

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

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.

•Needle – This valve has a small orifice and a threaded, needle-like plunger. It allows precise regulation of flow, although it is generally used for, and is capable of, only relatively small flow rates.and is capable of, only relatively small flow rates.

• Trunnions are designed for larger sizes and higher pressureshigher pressures

• Sizes from 1-1/2” to 60”• Pressures from ANSI 150 to API 10,000

Lower torque design allows ease of• Lower torque design allows ease of operation– Lower actuation costs

• Pressure drives the upstream seat into the ball. The ball remains stationary.

• Double block and bleed design (API 6D)g ( )– Upstream and downstream seats isolate the cavity.

The pressure in the cavity can then be relieved to prove the integrity of the seats.

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.
