True or False: Y-pattern globe valves can be used for boiler blow-off services.

1. True

2. False

3. Only if modified

4. Only in low-pressure applications

The correct answer is: False

Y-pattern globe valves are specifically designed to manage flow effectively and can handle various applications. However, they are not typically suitable for boiler blow-off services. This is primarily because boiler blow-off involves discharging hot water and steam at high pressure, and certain valve designs, including the typical Y-pattern globe valve, may not withstand the extreme conditions or provide the necessary safety and efficiency for such operations. In boiler applications, particularly for blow-off services, other types of valves are generally recommended that can handle higher pressure differentials and allow for quick and reliable operation. Therefore, the correct response regarding the suitability of Y-pattern globe valves for boiler blow-off services is that they should not be used in this context, hence the correct answer is false.
