Frequently asked questions
Common questions about Gate Valves from 3G Electric.
What is the difference between rising stem and non-rising stem gate valves?
Rising stem gate valves show the valve position visually and are ideal for applications where space allows, such as petroleum and gas lines. Non-rising stem valves are more compact, making them suitable for buried or confined installations like water mains. Choose based on space constraints and maintenance access.
Which gate valve materials are best for potable water systems?
Bronze and ductile iron gate valves are commonly used for potable water. Brands like NIBCO and Apollo offer lead-free bronze options that meet drinking water standards. Ensure the valve is certified for potable water service and check the pressure rating for your system.
Can you source gate valves for high-pressure steam or boiler blow-off applications?
Yes, we stock non-rising stem boiler blow-off gate valves and lever-actuated models designed for high-temperature steam service. These valves are typically forged steel or bronze with special trim. Contact us with your pressure and temperature requirements to find a suitable valve.
