# Is WOG and PSI the same?

## Is WOG and PSI the same?

WOG (Water, Oil, Gas), WSP (Working Steam Pressure), and PSI (Pounds per Square Inch) are closely-related – but not interchangeable – concepts manufacturers use to describe how much pressure a valve can withstand.

What does WOG pressure mean?

WOG (water, oil, gas) is an older term that is no longer used as frequently as it once was. It simply means that the valve is intended for use with water, oil or gas, with the exception of combustible gases.

### What does WOG mean on a gate valve?

& APPRENTICES, 1996: “The WOG (Cold Water, Oil, Gas) rating indicates the maximum non-shock pressure at ambient temperatures at which the valve may be used.”

What is the meaning of 1000 WOG?

A 1000 WOG ball valve is a ball valve that is ideal for water, oil, or gas industries and works with a maximum pressure rating of 1000 pound-force per square inch (PSI). Another term used to refer to your ball valve’s pressure rating is CWP, which means Cold Working Pressure at a temperature rating as high as 100 F.

## What does 150 PSI WSP mean?

steam pressure
WSP stands for water steam pressure or working steam pressure. It reflects the rating for the valve at water steam temperature. A valve rated at 600WOG/150WSP should be able to withstand 600 psi in a water or gas pipe and 150 psi if used in a steam supply system.

How do you calculate valve pressure ratings?

The relationship of NPS to DN can roughly be calculated as DN = NPS x 25. As NPS increases, the pressure rating of the flange decreases. In addition to flange sizes as measured in NPS, flange thickness can also vary and must be taken into account.

### What is 150 WSP?

WSP stands for water steam pressure or working steam pressure. It reflects the rating for the valve at water steam temperature. A valve rated at 600WOG/150WSP should be able to withstand 600 psi in a water or gas pipe and 150 psi if used in a steam supply system.

Can Ball Valves be used for natural gas?

Residential and commercial properties rely on gas ball valves to deliver liquefied petroleum gas (LPG), natural gas, manufactured gas, and gas/air mixtures to gas equipment and appliances. Gas appliances such as boilers, water heaters, furnaces, fireplaces, and gas stoves also commonly rely on a ball valve.

## What is a PSI rating?

The pressure put out by a power washer is measured in PSI (pounds per square inch), and the PSI requirements can vary based on what you’re aiming to clean. For example, it’ll take a lot less pressure to clean dust and salt from your vehicle than it will take to clean oil stains from your garage floor.

How do you calculate maximum pressure in a pipe?

Barlow’s Formula relates the internal pressure that a pipe can withstand to its dimensions and the strength of its materials. The formula is P= (2*T*S/D), where: P = pressure. S = allowable stress.

### What does 600 CWP mean on a valve?

The number represents the pressure rating, ie a 600 with CWP under it would mean the valve is rated to 600 PSI CWP.

What is the difference between wog and WSP valves?

WOG (water, oil, gas) is an older term that is no longer used as frequently as it once was. It simply means that the valve is intended for use with water, oil or gas, with the exception of combustible gases. Working steam pressure (WSP) indicates the maximum steam pressure that a ball valve can withstand at the highest temperature rating.

## What is the difference between 5g and Psi?

Some of these include: ½ PSIG (PSI gauge): This low pressure rating is used for gas valves that are used in appliances. 5G: This is a higher pressure rating for valves used in household gas piping systems.

What is the difference between CWP and Wog?

There are more specific approvals required for these applications. CWP stands for Cold Working Pressure and is an indication of the pressure rating for valves at a temperature up to 100°F. This is becoming a more common rating, as the WOG rating has a more complicated description.
