Which side should the ball valve be installed? The difference is significant, I propose to understand

Good afternoon, dear guests and subscribers of my channel.

Today, on the agenda - correct installation of ball valves.

At the very beginning of the article, I would like to touch on the production technology, since the installation of such products depends on this. Any ball valve is not a monolithic metal product, since the ball valve (ball) itself cannot be placed in the body and clamped between the gaskets, without first separating the body parts.

So, a ball valve is the result of a conveyor assembly, which is carried out by people after the preliminary production of parts on machine tools. And it consists of the following elements:

As for the ball valve, it is placed in the valve body and attracted by a nut, thereby ensuring a reliable position of the ball between the seals. And, since this fastener connection is collapsible, there is always the possibility of leakage, like any other threaded connection.

In fact, the crane functions in both directions, but the factory connection is the most vulnerable in the design. products and a huge share of existing cranes fail precisely because of the loss of tightness of this connection, and factors some:

  • marriage or poor quality of the product;
  • water hammer in the system;
  • service life of the product.

When installing ball valves, few people pay attention to this - but the fact remains. The valve is always installed with an integral part of the body to the pressure source of the working medium, be it water or gas. Sometimes, the crane itself becomes the cause of emergency situations.

Correct installation option:

In this case (picture above), in an emergency, if the body has burst along the seam, the ball valve still remains in the valve body. At the same time, due to the destruction of the product body, full tightness is ensured will not be, but the valve will contain the flow under pressure and it will be possible to avoid a flood (if it is water).

For professionals in their field - the installation of ball valves is carried out in exactly the same way as for electricians - phase on the right side in the socket of an electrical outlet and all this is considered a rule of good taste between masters.

I hope this article was useful to you, thank you for your attention!

Good luck with the repair and construction!
