WOG or CWP Valve for Steam WOG or CWP Valve for Steam colar (Mechanical) (OP) 23 Feb 10 19:46. I have an existing system that needs evaluation for compliance to B31.3 (as referenced by our local boiler code). The system is a deaerator for boiler feed water. One thing I have noted is that all of the ball valves on the unit do not have WSP ratings.
CWP: Cold Working Pressure: This designates the maximum non-shock pressure a product can operate at. “Cold” is generally defined as a range between -20°F to 100°F. WOG: Water, Oil and Gas: This was an older, generic pressure rating call-out which has been largely replaced by CWP (see above).
Re: What does WOG stand for on valves; Author: redwood (CT) The 200 WOG is a class rating that corresponds to the pressure specifications of ANSI 16.34. The valve is capable of many different pressures with different materials and temperatures. To fully comprehend its meaning you probably have to get a copy of the ANSI Spec.
“Cold” is generally defined as a range between -20°F to 100°F. WOG: Water, Oil and Gas: This was an older, generic pressure rating call-out which has been largely replaced by CWP. In this designation, “Gas” refers to any non-flammable, compressible fluid in a gaseous state. It does not imply a product’s suitability or third-party ...
Fire safety valve pressure ratings matter when choosing a valve for fire sprinkler and standpipe systems. QRFS reviews the differences between more than ten common terms manufacturers use to describe valves' pressure ratings, including WOG (Water, Oil, Gas), WSP (Working Steam Pressure), and PSI (Pounds per Square Inch).
The WOG rating stands for water, oil and gas and indicates the maximum pressure per square inch that the valve can take. Each valve is given a WOG rating, which should not be exceeded. Each different material that the valve is mad of has different limits in temperature and pressure.
MWP – Maximum Working Pressure or CWP (Cold Working Pressure) The maximum working pressure (pounds per square inch) at which a valve can be operated. The. maximum working pressures for various pressure classes, per Table 2.1 ot`API-GD, within temperature limits of —20°F and +100°F, are as follows:
Ball valves are the only type I use for natural gas. NG suppliers treat corrosive "sour gas" to keep it out of the domestic distribution network. ^_^
