A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. If there are no specific reasons listed previously to choose one vs. the other, then you should consider cost. These valves in all forms are used to create waterways, and it is therefore essential to understand the differences and their uses. Globe valves are good for regulating flow, whereas ball valves are better for on/off control without pressure drop.

Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. It can be a plug or ball valve.

These check valves can be swing check or lift check valve.

This is shown using small arrows next to the symbol as shown below. Similarly, the next two symbols are for three-way and four-way valve. There are dedicated symbols for a gate, globe, plug, ball valves which I will explain to you in minutes. There are a multitude of other valve types as well. The next symbol is the excess flow valve.

Vertical lift check valve. While considerably more expensive, Globe valves do still offer the many advantages listed (table 2). Valve Terminology; CV Factors – LVF Valves ; LVF Valve Material; Valve Symbols-> DICTIONARY - VALVE … Subsequent two symbols are of a check valve and stop check valve. Pictures.

Ball Valves .

Check valve symbol on piping and instrumentation diagrams. Ball valves are best suited to applications requiring on/off …

3-way and 4-way ball valves can contain additional detail that defines the type of ball drilling which is either a “T” or “L” port ball. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. Ball Valve: Withstand extreme pressure/temperature and high volume flow. Typically, a V-Port Ball Valve will be 35% to 50% less than a Globe Valve. Globe Valve Symbol: Check Valve Symbol 1: Ball Valve Symbol: PLug Valve Symbol: Butterfly Valve Symbol: Needle Valve Symbol: Check Valve Symbol: Diapragm Valve Symbol: Safety Relief Valve Symbol: Technical. Ball valve made of solid elements offers high durability, and have the ability to function perfectly even after long idle time. For decades globe valves were considered the industry standard in control valves. The arrow shows the flow direction. … Whereas, globe valves have a stem and plug, which strokes linearly, and gives them their other name of “stroke” valves. A check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Valve Weight; ISO & Achilles Certificate; Documentation; Valve Dimensions.

Another detail that may be represented in the diagram is the flow path in the non-actuated or de-energized state.

And ball, gate and globe valves are used to control flow of liquids.

Ball valves have a stem and ball, which turns horizontally, and are commonly referred to as “rotational” valves. V-Port ball valves are by far a more economical solution.
