The opening and closing member of the plug valve is a perforated cylindrical body that rotates about an axis perpendicular to the passage to achieve the purpose of opening and closing the passage. Plug valves are primarily used to open and close pipes and equipment media. The plug valve has the characteristics of long life, but the improper use will still shorten its service life. So how can we reasonably maintain it and extend the service life of the plug valve? The summary method is as follows: Adhesive labels are widely used for packaging of various kinds of commodities such as dairy products, food, household products, chemical products, beverage, drink water, juice, garment, gift, electrical appliances, shaped bottles and cups etc.We can make scratch off self adhesive label with QR code,series number,ect. Accept OEM order,it can be company's logo and website in your label.here are two basic types of self adhesive labels: permanent and removable. Each type of adhesive is made from a variety of glues depending on the conditions the label will have to endure, the length of time it is required and the environment or conditions of storage.

Self Adhesive labels are usually coated with an acrylic, rubber or water-based glue. Sticky labels can either be applied permanently or temporally.
Self adhesive labels can printed on by laser printers, inkjet printers, photocopiers or handwritten. Laser printers and photocopiers are a hot process and we recommend that A4 sheets of labels are only printed once for best results. The heat process evaporates the moisture in the adhesive each time it is passed through the printer.
(1) Avoid operating the valve at a small opening. If the valve is selected too large, work under a small opening, small throttling clearance, erosion is serious, the appropriate choice to adjust the diameter of the plug valve, the work opening increases, so that a large throttle gap, flushing weakened, can increase the service life.
(2) Harden the surface of valve cores, valve seats, valve stems, etc. in the easily-eroded areas or use cemented carbide.
(3) A step-down, high-pressure differential valve is used.
(4) Take the method of transferring the erosion position.
(5) Adopt methods to avoid cavitation cavitation.
