What does "200 WOG" inscribed on a six inch gate valve signify?

• A. The valve is not suited for wastewater service
• B. The catalog number is 200 and the valve can be used in "Waste or Grit"
• C. The manufacturer's code number
• D. The valve is rated for service at 200 psi for oil, grease or cold water

Answer: (D)

The inscription "200 WOG" on a six-inch gate valve indicates that the valve is rated for service at a pressure of 200 psi and is suitable for water, oil, and gas applications. Specifically, "WOG" stands for "Water, Oil, and Gas," which confirms the types of fluids the valve can handle effectively. This rating is important because it informs operators and engineers about the maximum pressure the valve can safely withstand without leaking or failing during operation. In a wastewater collection system, understanding the pressure rating is crucial to ensure that the infrastructure can handle the dynamic conditions and potential surges in pressure that may occur in the system. Other options do not accurately describe the significance of “200 WOG.” The valve being unsuitable for wastewater service, having a catalog number, or representing a manufacturer’s code number doesn't provide the relevant information that is essential for determining operational safety and application versatility of the valve.
