The German DINF5 standard gate valves produced by Ruitong Valve, as well as the DIN series gate valves PN10-PN120, are used to cut off or connect media in pipelines with operating temperatures of -29~425 ℃ (carbon steel) and -40~500 ℃ (stainless steel).
The product design and manufacturing comply with the requirements of the American National Standard ANSIB16.34 and the American Petroleum Institute Standard API600/API602/API603.
Compact structure, small volume, good rigidity, and safe and reliable sealing.
The closing element (gate) adopts an elastic structure, which can automatically compensate for valve body deformation caused by abnormal loads or temperatures during operation. Therefore, the sealing is reliable and will not produce gate wedges.
The API6D flat gate valves produced by RTV Ruitong Valve are suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, as well as venting systems and steam storage devices. The flat gate valves are used as opening and closing equipment. The Z43 type single gate flat gate valve with diversion holes is suitable for long-distance natural gas extraction and purification pipelines.
There are three types of valve cover designs for internal threaded and socket welded gate valves. The first type is a bolt type valve cover, which is connected by a concave convex surface and uses stainless steel strip and flexible graphite winding gasket. Ring connection can also be used according to requirements. The second type is a welded valve cover, which is sealed by threads and welded, and can also be directly welded according to requirements. The third type is a self sealing valve cover, which is connected to the self sealing valve cover by threads.
