What precaution should be taken when using venturi type gate valves?

• A. Install bypass lines
• B. Ensure proper insulation
• C. Fit the piping system with low point drains
• D. Use only in ambient temperature conditions

Answer: (C)

When using venturi type gate valves, fitting the piping system with low point drains is important to prevent the accumulation of liquids that could cause damage or hinder operation. This type of valve is often used in applications where flow measurement or significant pressure changes are present, and it is crucial to maintain efficient flow conditions. Low point drains serve to remove any condensation or liquid that may gather in a section of the pipe, particularly at the low points of a system. This is especially vital in applications where the medium flowing through the valve may change state (e.g., from vapor to liquid), which can affect the performance of the valve and the system as a whole. While the other options could have their relevance in certain contexts involving valve installation or use, they are not specifically protective measures directly associated with the operational characteristics and potential issues related to venturi type gate valves. For example, installing bypass lines may be useful for maintaining flow in some scenarios but does not address the specific concerns about liquid accumulation. Proper insulation can be important for thermal management, yet it does not directly relate to the unique challenges posed by venturi valves. Hence, ensuring low point drainage effectively mitigates one of the principal concerns associated with these types of valves.
