Product Description

Q11F-16T Brass Ball Valve

The Q11F-16T brass ball valve evolved from the stopcock. Its opening and closing element is a ball, which rotates 90° around the valve stem axis to achieve opening and closing. The sealing surface of the Q11F-16T brass ball valve is made of polytetrafluoroethylene (PTFE), which features excellent sealing performance. It is widely used in buildings, plumbing systems, waterworks, etc., and is suitable for both cold and hot water.

Specification

Brass Ball Valve Advantages 

1. Low fluid resistance; its resistance coefficient is equal to that of a pipe section of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable; currently, ball valves widely use plastic as the sealing material, providing excellent sealing performance, and are also widely used in vacuum systems.

4. Easy to operate; quick opening and closing; only a 90° rotation is needed to go from fully open to fully closed, facilitating remote control.

5. Easy to maintain; the ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement convenient.

6. When fully open or fully closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve sealing surfaces during medium flow.

7. Wide range of applications; suitable for pipe diameters from a few millimeters to several meters, and applicable from high vacuum to high pressure.

Q11F-16T brass internal thread ball valve, also called threaded brass ball valve. The Q11F-16T model is an internally threaded ball valve with internally threaded interfaces at both ends. The sealing surface is made of polytetrafluoroethylene (PTFE) material, which has the characteristics of good sealing performance.
