Frequently asked questions

Common questions about Boiler Blow from 3G Electric.

How do I choose between a gate valve and a globe valve for boiler blowdown?

Gate valves are typically used for on/off service where minimal pressure drop is needed, while globe valves offer better throttling control. For boiler blowdown, globe valves are often preferred for precise flow regulation, whereas gate valves suit quick isolation. Consider your system pressure and blowdown frequency.

What pipe marker options are available for boiler blowdown lines?

We stock wrap-around, adhesive, snap-on, and roll-form pipe markers from BRADY. Choose based on pipe diameter, surface condition, and whether you need indoor or outdoor durability. Adhesive markers suit clean surfaces, while snap-on markers are ideal for quick installation without tools.

Are these boiler blow valves suitable for high-pressure steam systems?

Yes, the bronze valves from UNITED BRASS WORKS are designed for boiler blowdown service, typically rated for pressures up to 200 psi. Always verify the specific pressure rating and temperature limits for your system, and consult our team for assistance with high-pressure applications.
