Is a WOG valve good for steam?

Acceptable working pressure for all equipment decreases as temperatures increase. The WOG rating is always higher than the WSP rating for a valve or fitting. Definitions: SWP: Steam Working Pressure: This designates the maximum recommended steam pressure a product can operate at.

What is a WOG rating?

WOG stands for Water, Oil and Gas and is the non-shock pressure rating for valves at an ambient temperature.

What does 200 WOG mean on a gate valve?

This 1.5-inch angle valve is marked “200 WOG” (and “125 WSP”), not “200 PSI.” Pipefitters classify valves by their pressure and temperature limitations. The Steam Working Pressure (SWP) rating, sometimes known as Working Steam Pressure (WSP), indicates the maximum allowable pressure from hot, vaporized water.

What does 1000 WOG mean on a valve?

As stated by JLSeagull, WOG stands for water-oil-gas. It should intend the same as CWP (Cold Working Pressure), that is the maximum pressure rating allowed under normal “ambient” temperature conditions, -29°C to 38°C. 1000 WOG is 1000 psi for gas-oil-water. (Note 2300 kPa = 333.6 psi)

What does Wog mean on a ball valve?

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 Wog rating for steam valves?

WOGstands for the water, oil, and gasrating for the valve and reflects the maximum pressure capability of the valve at 100 F. WSPstands for working steam pressure and reflects the maximum pressure rating for the valve at the highest temperature rating. Acceptable working pressure for all equipment decreases as temperatures increase.

What does wog and WSP stand for in plumbing?

Common (sometimes older) ratings are WOG and WSP (or sometimes SWP). WOG stands for the water, oil, and gas rating for the valve and reflects the maximum pressure capability of the valve at 100 F. WSP stands for working steam pressure and reflects the maximum pressure rating for the valve at the highest temperature rating.

What is the difference between wog and CWP?

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. Both WOG and CWP refer to the pressure rating of the valve.
