Speaking of PPR ball valves, in fact, we can apply them in our lives, but because most of them are operated by professionals during construction, many consumers may not be familiar with this product. Below, the editor will give you a detailed introduction to the relevant knowledge of PPR ball valves. Interested friends can take a look.

What is PPR ball valve


A ball valve is a valve whose opening / closing part (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid adjustment and control. Among them, the hard-sealed V-ball valve has a strong shear force between the V-ball core and the metal seat of the welded hard alloy. And other media. The multi-way ball valve can not only flexibly control the merge, split and flow direction of the medium on the pipeline, but also close any one channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline.


PPR, also known as random copolymer polypropylene (PPR), has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the advantages of random copolymer polypropylene with high transparency, which can be widely Used in the production of pipes, sheets, daily necessities, packaging materials, household appliance parts, and various films. Generally, the ball valve adopts live connection, and the live joint adopts PPR joint.


PPR ball valve features


The PPR ball valve has wear-resistant properties. Since the valve core of the hard seal ball valve is alloy steel spray welding, the sealing ring is alloy steel surfacing welding, so the PPR ball valve will not cause too much wear when switching. The sealing performance is good, because the seal of PPR ball valve is manually ground, and it can not be used until the valve core and the sealing ring are completely matched. Therefore, his sealing performance is reliable. Because the bottom of the sealing ring of the PPR ball valve uses a spring to tightly hold the sealing ring and the valve core, the switch is very light when the external force exceeds the preload of the spring. PPR ball valves have a long service life and have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
