Gate valve manufacturers in the use of occasions and the choice of factors

In recent years, as a control valve and flow direction of water as a tool, in the form has changed. Over the past commonly used in dual-use flashlight flashlight dual butterfly valve gradually being replaced by butterfly valve has the advantage of small size, light weight, easy installation, the resistance coefficient. The disadvantage is that if the precision of fabrication and installation is not enough, or impurities in the water were more easily lead to lax leaking valve closure phenomenon, whereas the traditional valve leaks are hard, but the size large; in particular, a large diameter gate valve, but also large and bulky install the demolition is not easy; more importantly, due to large volume, leading to an area of increased pumping station, construction costs increase. Therefore, pumping station design, tendering selected valve should consider the following two questions:

     1 Use

Use of non-space restrictions, debris in the water more, easy to plug in an important position of the valve, dual valve flashlight can be used; contrary valve can be used, in particular, used in the pumping station renovation project in the butterfly valve can be used for the effective use of existing pumping station space, to achieve the same area of the former pump house under the premise of increased supply (row) of water purposes.

     2 manufacturers

Choose a larger scale, a longer productive life, prestige, quality clearance and be responsible for installation and commissioning of the valve manufacturers. With the butterfly processing accuracy continues to improve, the quality will get better and better, leakage problems would be solved, when the butterfly valve will replace the old valve, which is the development trend of valves.
