Q: The hot water pipe ball valve what brand alone?: Such as the bathroom taps are generally alternating hot and cold water, will be pulled out from the faucet two hoses, and then connected to the wall, embedded in the wall of the interface is angle valve. Because the heating pipe at the corner of the shape of 90 degrees angle, and the ball valve is straight through, so the basic difference between angle valve and spherical valve is that the angle valve exports and imports into 90 degrees right angle. rn usually angle valve mainly plays four roles: rn transfer within rn out nozzle; when the water pressure is too large, can be adjusted in the triangle valve above, turn down; the rn with switch function, if the leading Water Leakage phenomenon, can promptly put the triangle valve off, instead of the total valve closed in the home.

Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness?

The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.Nominal outer diameter is expressed by DN, refers to the outer diameter of the pipe. Such as the outer diameter of 32mm PVC-U pipe can be expressed as dn32. The specification of PVC-U pipe for building drainage is indicated by DN (nominal outer diameter) * e (pipe wall thickness) (GB-T, 5836.1-2006).
