Product Description

Product overview
The ball sealing ring in the Q641M pneumatic high temperature ball valve adopts the processing technology and new sealing material, so that the surface roughness and roundness of the ball meet the standard requirements, thus improving the sealing performance and service life, the ability. The plate handle drives the valve stem to drive the ball to rotate, so that the medium passes smoothly.

Ball valve installation precautions:
1. Installation and construction must be careful, do not impact the valve. 2. Before installation, the ball valve should be inspected, check the specifications and models, and identify whether there is damage, especially for the valve stem. But also turn a few times to see if it is crooked, because during transportation, it is easy to knock the valve stem. Also remove the debris in the valve. 3. When the ball valve is lifted, the rope should not be tied to the handwheel or the valve stem, so as not to damage these parts, and should be tied to the valve body. 4. For the pipe connected to the ball valve, be sure to clean it. Compressed air can be used to blow away iron oxide filings, mud and sand, welding slag and other debris. These debris, not only easy to scratch the sealing surface of the ball valve, including large particles of debris (such as welding slag), but also can block the small valve, so that it fails. 5. When installing, leave the position of the valve handle to rotate. 6. The ball valve cannot be used for throttling. 7. Ball valves with transmission mechanisms should be installed upright.
