It is well-known to us that a ball valve is a valve with a spherical disc containing many round holes. The disc is specified to implement the opening and closing of the valve by rotating upon the valve handle. And it is able to move within 90 degrees. The structure leads ball valves to be proper in the field of switches and stop valves. They are generally used to stop or control flows in pipes. And the design enables ball valves to regulate the flow with convergence, segregation and flow switch. In fact, ball valves are widely employed to the fields of petroleum refining, pipeline, chemical, paper, pharmaceutical, water, electricity, municipal and steel industry and so on, which actually play a decisive role in national economy.

It is true that the characteristics of ball valves benefit a lot during the operating process. Firstly, it is light with a straightforward structure. The flow would flow smoothly. Secondly, the two discs ensure the tightness. As materials for the sealing surface are commonly various plastics, the favorable leak tightness directs the valve to be widely used, even in the vacuum system. Thirdly, it is easy operated. The handle can be rotated from a long distance within 90 degrees in a short time. And it is certain that the straightforward and active structure is favorable for removal and replacement. Fourthly, the flow would not erode the sealing face as a result of full cut-off or full open. At last, the valve body can be either integral or modular.

Apart from the advantages, there are some aspects that ball valves need to be improved. It is the small range of performing temperatures. Because material of the sealing surface can’t bear high temperature. Thus, it is a good chance for the future manufacturers to overcome this shortage by using other materials. It is certain the specifications for ball valves should regulated according to the GB12237-89, GB/T15185-94,GB8464-87,GB8465.3-87,JB/T53167-94 and JB/Z246-85. It is important to design and produce them accordingly for the consideration of safety and performance. And it is necessary to install and operate the machine based on the instruction. Then, it can function at its best.

Mezzanine system shelving allow for conversion of unused vertical air space into safe, efficient storage areas for a fraction of the cost of the move. Mezzanine shelfs also offer a number of direct and indirect economic perks to facilities owners. Mezzanine shelving systems provide an incredible level of safety fully compliant with regulatory codes and offer a high level of adaptability to any number of industrial and warehousing environments.

Floor space limitations not only limit the amount of equipment and materials owners can house within the facility, but they can also create safety issues such as trip and fall hazards when things become too closely packed together. Owners often immediately consider a move when space becomes limited not only to accommodate inventory and operations, but also to ensure a safe working environment. The cost of moving, however, is enormous for industrial facilities. On the other hand, investing in mezzanine system shelving requires only a fraction of the cost of moving and increases available storage space 100-150 percent on the average. Adding mezzanine shelving to existing floor space eliminates months, and in some cases, years, of waiting for a new building to be finished.

Tax codes classify multi-tier mezzanine shelving systems as equipment, not real estate. As expanding a facility or building a larger plant will obviously place you in a higher property tax bracket, converting vertical space with a mezzanine system minimizes property tax increase and offers depreciation tax breaks associated with equipment. This again further reduces overhead and allows operations to increase profits through lowered expenditures. The versatility offered by these systems offers a variety of options in almost any facility. Mezzanine shelving assemble as easily as standard shelving and provide storage, staging, workspace, and even office space. All steel components of the system, including heavy-duty columns designed for industrial loading capacity, come pre-fabricated from the manufacturer and require no drilling or welding. Owners can choose from a number of stairs, steel or concrete decks, and handrails to ensure full code compliance for particular geographic areas and specific industries.

Because of the way mezzanine systems assemble, they offer a flexibility that allows for change in size and location as your industry evolves and your facility adapts in response. They can be moved or enlarged at will, allowing for multiple upgrades and minimizing any need for replacement. As customized and highly reliable pieces of equipment, most companies can design them specifically for your current needs and any future changes you foresee.
