Valve has a fluid resistance small, the sealing surface by the impact of the erosion of small; not to change the media flow; not spoiler, small pressure drop; hoist torque small; the structure of the short length; process performance and application of pressure, temperature, a wide range of characteristics such as gate valve parts exercise direction and the vertical flow of medium (for the throttle can not be used), is one of the most commonly used cut-off valve, used to cut off or connected to the media pipeline.

● Materials variety of goods, packing, gaskets may be different based on user's request for reasonable matching can be applied to all kinds of pressure, temperature and medium conditions. High-temperature pressure valve high-quality heat-resistant alloy steel parts manufacturing, sealing surface using stellite (stellite) Co-based cemented carbide, safe, reliable, stable performance, long service life.
● Valve valve cover reasonable structural design, wall thickness by the strict control and inspection in line with national standards and the United States GBl2234 standard ANSI B16.34 requirements, high strength, rigidity, and flow resistance small.
● the use of a flexible wedge gate structure, as the whole cast is made of exquisite design, good sealing performance.
● stem the use of heat-resistant alloy steel, by rough forging and quenching and tempering and surface nitriding treatment, have a good comprehensive mechanical properties and corrosion resistance, anti-scratch.
● use of reversing valve sealing structure may be non-stop machine conditions to carry out maintenance or additions and changes to fill.
● stem nut used with the function structure, with the stent site set up to connect ball bearings, rotating torque small, easily headstock.
● According to the user or engineering requirements to connect the form of a reasonable choice, multi-mode of operation or to meet different application requirements.
● SMC and the use of electric valve DZW series valve electric device, with a shell of small, light weight, full-function can be programmed to use features such as computer matching.
