Q11F Threaded Brass Ball Valve Overview
The Q11F threaded Brass ball valve is a brass globe valve that uses threaded connections to quickly open and close by rotating the valve stem to drive the ball to move 90 degrees. The valve body is made of forged brass with a compact structure, and the sealing surface is usually covered with polytetrafluoroethylene (PTFE) to ensure good sealing performance. The working temperature range of this valve is generally -20 ℃ to 150 ℃, suitable for pipeline systems with nominal pressure PN16 and below. It is widely used for controlling non corrosive fluid media such as water, oil, and gas, and is commonly found in building water supply and drainage, HVAC, household appliances, and general industrial equipment pipelines.

Q11F Threaded Brass Ball Valve Features
1. Corrosion resistant and safe material: The valve body is made of forged brass, which has high strength and corrosion resistance, no rust pollution, suitable for drinking water and general fluid media, and is safe and reliable.
2. Excellent sealing performance: The sealing surface of the sphere is covered with soft sealing materials such as PTFE, which has a low friction coefficient and good sealing performance, and can achieve basically no leakage under long-term use.
3. Compact and lightweight structure: With a small overall volume and light weight, coupled with threaded connections (internal or external), the installation space requirements are low, making it easy to arrange in compact pipelines.
4. Easy and fast operation: opening and closing only requires rotating the handle 90 degrees, making it easy and fast to operate, with low flow resistance, and can quickly cut off or connect pipelines.
5. Economical, practical, and easy to maintain: Low manufacturing cost, high cost-effectiveness, minimal daily maintenance requirements, and can be replaced as a whole if the seal fails, resulting in low maintenance costs.
