Q41J rubber lined flange ball valve advantages

1. Fluid resistance is small, full diameter ball valve basically no flow resistance.

2. Simple structure, small size, light weight.

3. Tight and reliable. It has two sealing surfaces, and the sealing surface material of the ball valve is widely used in all kinds of plastics, good sealing, can achieve complete sealing. It has also been widely used in vacuum systems.

4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90°, convenient for long-distance control.

5. Convenient maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.

6. In full open or full closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the corrosion of the sealing surface of the valve will not be caused when the medium passes through.

7. A wide range of applications, from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.

8. Because the ball valve has wiping properties during the opening and closing process, it can be used in the medium with suspended solid particles.

Q41J rubber lined flange ball valve structure features:

The ball valve uses a ball with a circular through-hole as the opening and closing part, and the ball rotates with the stem around the center line of the valve body to realize the opening and closing of the valve.

The ball series of our factory is Q41 type, which is duplex structure type.

1. Special molding process is used to make the sealing surface compact and good, and the combination of V-type PTFE packing makes the valve achieve zero leakage.

2. The ball and stem are cast as one, which eliminates the possibility of the stem rushing out of the pressure bearing parts due to pressure changes, and fundamentally ensures the safety in use.

3, the use of plastic lining process, resistant to strong corrosion of the medium.

Q41J rubber lined flanged ball valves are widely used in many industrial fields due to their excellent sealing and corrosion resistance, including:

Chemical industry: used to control the flow of various acid, alkali, salt and other strong corrosive media.

Petroleum industry: used for control and regulation of pipeline systems 1.

Electric power industry: used for heat pipe and circulating cooling water system, etc.

Pharmaceutical, food, paper, metallurgy and other fields: widely used in these industries in the fluid control

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition
